  • Title: UbuntuSolutions
    Descriptive info: .. UbuntuSolutions.. MythTV 0.. 22 in Karmic 9.. 10.. 3.. Posted by.. bikethetam.. Fri, 27 Nov 2009 22:08:00 GMT.. This is the tale of my attempts, eventually successful, to setup Mythbuntu on a newly purchased HP slimline desktop s5280t.. Hardware.. This is the decription of the machine: it's HP Slimline s5300.. It comes with a quad-core CPU, 6GB of RAM and 640GB, but that doesn't matter for MythTV.. What matters is the following list of devices:.. Tuner card: Hauppauge WinTV-HVR1255.. Remote control: TSGH-IR01 (the IR receiver plugs into the tuner card in what looks like a simple jack).. Video Card: Nvidia G210 with HDMI.. Samsung LCD TV with DVI input (among others).. Setup.. The initial Mythbuntu setup was uneventful.. I installed Karmic from scratch without issue.. During installation, a few MythTV setup screens are proposed to do the initial configuration (tuner card, SchedulesDirect subsciption, channel lineup,.. ).. That went equally well except for the remote control: none of the devices in the list matched mine.. Anyways, the setup completed and I could start MythTV.. I must say I was pleasantly surprised, the UI came up and using the keyboard, I could actually watch TV.. There were a few annoying details, like the size of the UI that doesn't exactly match the size of the TV screen and a very slim noise band at the top of the image on 4:3 channels.. But the major issues were of different kind:.. no sound.. no remote.. Sound problem.. The image comes from the video card through the HDMI port and I was hoping the sound would come out of the analog sound output of the computer and to the analog sound input of the TV.. That's how it was working on my previous MythTV installation (Gentoo + Acer machine).. The DVI input of the TV is supposed to work in concert with the analog sound input right next to it, but in this case it didn't: strangely, sound is coming out of the analog sound port but the TV ignores it.. After a little digging, I found that the TV can actually receive sound through HDMI.. At least that's what it tells the video card when it sends its firmware signature (EDID) to the video card.. The video card, naive as it is, believes it and replies to the TV that it's going to do just that.. The TV is happy, it turns off the analog sound input and listens on HDMI.. Unfortunately, that's all too sophisticated for the Nvidia driver of the video card (version 185 by default by I also tried 190 to no avail).. The nvidia driver doesn't know how to process sound coming from the motherboard.. But it does know how to send sound to the TV and that's what it does, it sends an all blank soundtrack to the TV.. The solution is on this page:.. Converting analog sound to HDMI.. It consists in modifying the EDID information submitted by the TV and remove the bits about receiving sound through HDMI.. The updated EDID must then be saved into xorg.. conf.. The video card will subsequently read the EDID from there instead of getting it from the TV and will stop telling the TV that sound is coming through HDMI which will cause the TV to listen on the analog input.. That worked like a charm for me (after a couple of reboots).. Remote troubles.. Hauppauge 1250 IR receiver.. The remote control that HP sent with the computer is designed for Windows Media Center Edition which led me to believe it fell into the mceusb category of remotes that can be used with LIRC and MythTV.. But I was mistaken, the IR receiver is not a USB device, instead it plugs in directly into the tuner card (Hauppauge 1250).. Again, the issue here is with too recent hardware and outdated drivers: the driver for the Hauppauge tuner card doesn't recognize the IR receiver and completely ignores it.. There's no fix as of yet.. That's too bad because this remote control looked pretty solid compared to all the remotes that can be bought online.. The full explanation can be found on.. MythTV wiki.. USB Remote Control.. I then went to buy that.. wireless PC remote I found on Amazon.. It seemed standard enough and I was hoping I could use the other remote described above on the new IR receiver.. It didn't work as planned.. The first thing that is supposed to happen when plugging in a USB IR receiver is to have LIRC detect the device (should show up in dmesg) and that should be immediately followed by the device appearing under /dev with the name /dev/lirc0.. I got LIRC to detect something:.. Nov 22 14:18:35 ibiza kernel: [ 15.. 507820] lirc_dev: IR Remote Control driver registered, major 61 Nov 22 14:18:35 ibiza kernel: [ 15.. 592792] lirc_mceusb: Windows Media Center Edition USB IR Transceiver driver for LIRC 1.. 90 Nov 22 14:18:35 ibiza kernel: [ 15.. 592826] usbcore: registered new interface driver lirc_mceusb.. but nothing showed up as /dev/lirc0.. The testing LIRC tool 'irw' was not mute, some garbage got printed but not at all what's supposed to be printed.. In fact, even though LIRC didn't recognize the IR receiver, I could use the remote to do some basic operations: the up, down, left and right keys were doing exactly what is expected from the arrow keys of a regular keyboard.. So I could use it to do the most basic navigation operations on the MythTV menus.. Interesting but not good enough.. After lots of googling, I finally realized that the remote was in fact recognized as a keyboard and a mouse by the system.. That's bad news because that means I won't be able to use the other remote with that receiver.. Anyways, this is called an HID remote and LIRC has a driver for that, it's called devinput.. That.. Archlinux wiki page.. has the lircd.. conf file to be used with such a device.. I found only later that dmesg was showing the HID device:.. Nov 22 16:48:42 ibiza kernel: [ 3.. 247892] input: HID 073a:2230 as /devices/pci0000:00/0000:00:1d.. 1/usb7/7-1/7-1:1.. 0/input/input3 Nov 22 16:48:42 ibiza kernel: [ 3.. 247957] generic-usb 0003:073A:2230.. 0001: input,hidraw0: USB HID v1.. 10 Keyboard [HID 073a:2230] on usb-0000:00:1d.. 1-1/input0 Nov 22 16:48:42 ibiza kernel: [ 3.. 247968] usbcore: registered new interface driver usbhid Nov  ...   No need for that with the MyTouch as it features a 'back' button.. So if you click on a URL in the email client, it takes you to the web browser and once you're done with the page, you just have hit the 'back' key and it gets you back straight to the message you were reading.. Responsiveness.. Now, the major.. strengths of the iPhone are fluidity and responsiveness.. As soon as the finger starts sliding on the screen the web page or the list starts rolling, there's no delay (except when browsing complex web pages as they're being loaded).. The MyTouch can't compete on this front, it often takes a few tenths of a second before the screen starts moving.. It's quite tolerable though.. I blame the ability of Android to multitask vs the foreground applications only in the iPhone for the difference.. Web browsing.. Again, this is a strong point of the iPhone.. A web page appears in full width at first, and a simple double tap on a text column or a pinch over the area that you want to enlarge shows you the desired area with the right zoom level.. I find it very intuitive and effective.. The Android approach is different,.. Android doesn't have multitouch.. So here is how it works: the initial view of the page is zoomed in on the top left of the page at a level where the text is readable.. Whenever you slide the screen, the zoom +/- button will appear.. The zoom step is quite small and it might take many taps to get an overview of the full page.. Tapping on the piece of text you're interested in has no effect.. Another major difference is that once the focus is on a text column, the Android.. browser will reformat it to fit in the width of the screen.. , you can then zoom in or zoom out and the screen and the text still occupies the full width and no more than the width of the screen.. It takes some getting used to, and it's only been a day but I can now find my way around different areas on a page quite easily.. The web browser is another part of the interface where the back button is greatly appreciated.. It's also very easy to access the the address bar as there is a key for that on the phone: that's the very versatile search key which changes purpose depending on the application.. Another useful key is the menu key that gives easy access to settings and bookmarks.. In the end all those keys at the bottom of the phone.. save a lot of screen real estate.. and that's major plus for the MyTouch.. Final advantage of the Android browser over the iPhone's: better caching.. The iPhone is quite bad at managing it's graphic memory.. When scrolling up and down, it's very common for the content to stay invisible for several seconds while being hidden behind a frustrating grey and white grid.. No such thing on the MyTouch.. Email reader.. The iPhone and Android email readers have a lot in common including flaws.. One missing feature in the iPhone email app is the ability to zoom on message the same way it can be done on a web page.. Well, this flaw is unfortunately shared by Android.. Okay, it's not entirely true, there are actually.. no less than 3 email applications.. in Android, one for Gmail, one for MS Exchange and one for your other IMAP or POP accounts.. Oh wait, 4 if you count the gmail web application.. This is definitely silly and I hope Google will consolidate all those apps in a future version.. Anyways, out of those 4 application,.. only the Exchange one allows you to zoom in and out.. In the other 3, you might have to scroll left and right for every line of the email you are tediously trying to read.. Main menu.. The Android front page is a breath of fresh air compared to the iPhone, you can setup the background the way you like, organize your applications icons on any page or maybe in a folder with the name of your choice.. The apps that are less often used can be left out of the front pages and stay in the full app list if you want to.. There is a.. notification bar.. at the top of the front page that shows not only the usual mobile phone indicators (signal bars, time.. ) but it also shows icons whenever emails are received, downloads complete or wifi networks are available.. Where it gets interesting is that you can.. drag that bar down.. , and then it show a detailed list of the new events that you can select to go directly to the appropriate application.. Very neat.. Conclusion.. Okay, I admit it, I'm thrilled with my new phone.. Besides everything I already mentioned, the screen quality is excellent, the camera takes great pictures, Google Maps coupled with the GPS is terrific.. I should really mention the Amazon app where it's possible to scan barcodes wherever you are and immediately see the item in the Amazon website, this feature is just amazing.. android.. 12 comments..

  • Title: Category ubuntu, everything about ubuntu
    Descriptive info: Sun, 12 Jul 2009 22:14:00 GMT.. Since Jaunty was released, most computers with Intel GPU have suffered from dismall video performances.. It's not only about videos, it's also about browsing the web with Firefox, scrolling through pages is slow, sometimes blocks, and compiz effects suffer from occasional flashes.. This fix is for the AAO D150 which is equipped with Intel 945GM.. # lspci | grep 945 00:00.. 0 Host bridge: Intel Corporation Mobile 945GME Express Memory Controller Hub (rev 03) 00:02.. 0 VGA compatible controller: Intel Corporation Mobile 945GME Express Integrated Graphics Controller (rev 03) 00:02.. 1 Display controller: Intel Corporation Mobile 945GM/GMS/GME, 943/940GML Express Integrated Graphics Controller (rev 03).. I tried several things.. I started experimenting with the instructions at.. Jaunty Intel Graphics Performances Guide.. (safe solution) but it didn't help, if anything it got worse.. Then I reverted to the regular driver (aptitude was of great help here, I used aptitude remove xserver-xorg-video-intel and it kindly offered me to downgrade to the regular jaunty version instead of completely removing the package).. I found that.. page.. that explains how to revert to version 2.. 4 of the driver.. The instructions in the article work just fine and after restarting X, the video performances are back to normal.. In short:.. Add to /etc/apt-sources.. list:.. deb http://ppa.. launchpad.. net/siretart/ppa/ubuntu jaunty main.. Add the server key:.. sudo apt-key adv --recv-keys --keyserver keyserver.. ubuntu.. com 0xce90d8983e731f79.. Install the 2.. 4 package:.. sudo aptitude install xserver-xorg-video-intel-2.. 4.. Restart X and you're done.. 4 comments.. 25.. Fri, 03 Jul 2009 17:28:00 GMT.. Important update.. :.. The official Firefox-3.. 5 is now available in the universe repositories.. You don't need to do any of the following, just apt-get install firefox-3.. 5.. No need for any ubuntu-mozilla-* line in /etc/apt/sources.. list.. To uninstall firefox-3.. 5 that was setup using ubuntu-mozilla-*, follow the removal instructions below.. After digging around a little bit more, I found that there was another,.. safer.. , repository for Jaunty with firefox 3.. 5: ubuntu-mozilla-security.. For those of you who don't want the daily updates of firefox, which will deliver experimental releases on occasions, you should use the security repository instead of ubuntu-mozilla-daily.. sudo apt-key adv --keyserver keyserver.. com --recv-keys 7EBC211F.. Add the following line at the bottom of /etc/apt/sources.. net/ubuntu-mozilla-security/ppa/ubuntu jaunty main.. sudo apt-get update sudo apt-get install firefox-3.. 5 firefox-3.. 5-gnome-support.. If had already installed firefox-3.. 5 from the daily repository.. and you want to switch to the security one, you first need to remove the ubuntu-mozilla-daily line from /etc/apt/sources.. list and remove firefox-3.. 5 that came from that repository:.. sudo apt-get remove firefox-3.. 5 xulrunner-1.. 9.. 1-gnome-support xulrunner-1.. 1.. Only after that you should run apt-get install firefox-3.. 5-gnome-support.. no trackbacks.. 25 comments.. 58.. Thu, 02 Jul 2009 03:45:00 GMT.. :.. 5 that was setup using ubuntu-mozilla-*, follow the instructions at.. ubuntu-mozilla-security.. Only follow the instructions below if you want to be on the bleeding edge.. Firefox 3.. 5 was officially released yesterday and it brings significant improvements in terms of speed, tab management and support of HTML5.. Ubuntu does not automatically propose the upgrade so you need to help the system find the newer packages.. Let's start by listing the least effective ways of getting those packages.. Installing from Canonical repositories.. When searching inside of Synaptic Package Manager or using apt-cache, you are going to find firefox-3.. Unfortunately, it's been there since the release of Jaunty and it has not been updated since then.. At the moment, only the beta 4 for is available and believe me you don't want it.. $ apt-cache showpkg firefox-3.. 5 Package: firefox-3.. 5 Versions: 3.. 5~b4~hg20090330r24021+nobinonly-0ubuntu1 (/var/lib/apt/lists/us.. archive.. com_ubuntu_dists_jaunty_universe_binary-i386_Packages) Description Language: File: /var/lib/apt/lists/us.. com_ubuntu_dists_jaunty_universe_binary-i386_Packages MD5: b670b07084b5a79b912d14c4307acda4.. Installing from mozilla.. That's a better option.. The process is the following:.. download the.. tar.. bz2 file.. uncompress it under ~/firefox.. make sure no other instance is already running.. start firefox 3.. 5 by running ~/firefox/firefox.. It works fine but there are several problems with this approach:.. It completely shortcircuits the package manager which means that you will have to install future updates independently of the rest of the system.. When Ubuntu gets upgraded, it's very likely this firefox installation will stop working as it depends on libraries that will have changed version.. This firefox installation will the same ~/.. mozilla directory to store your personal settings as the Ubuntu version of Firefox (3.. 0.. 11 as of today).. Confusion and pain will inevitably follow.. Unfortunately the last installation option described below has that same disadvantage.. Now the better solution.. Setting up the ubuntu-mozilla-daily repository.. You can add to your system a repository maintained by the mozilla developers.. deb.. http://ppa.. net/ubuntu-mozilla-daily/ppa/ubuntu.. jaunty main.. Let Ubuntu know the identification key of this repository:.. com --recv-keys 247510BE.. Refresh your system cache:.. sudo apt-get update.. Now, same as with the first option, the package that you want is firefox-3.. The difference is that now, the version available is the right one.. 1~hg20090629r26036+nobinonly-0ubuntu2~umd1~jaunty (/var/lib/apt/lists/ppa.. net_ubuntu-mozilla-daily_ppa_ubuntu_dists_jaunty_main_binary-i386_Packages) Description Language: File: /var/lib/apt/lists/ppa.. net_ubuntu-mozilla-daily_ppa_ubuntu_dists_jaunty_main_binary-i386_Packages MD5: b670b07084b5a79b912d14c4307acda4.. You need to setup this package, latex-xft-fonts and also firefox-3.. $ apt-get install firefox-3.. 5-gnome-support latex-xft-fonts.. At this point, there are 2 different versions of Firefox coexisting on the system, 3.. 11 and 3.. When you run firefox from the command line or when you select it from the Applications menu, version 3.. 11 is fired up.. It might be convenient to make the newer version the default:.. $ sudo su $ cd /usr/bin $ ll firefox* lrwxrwxrwx 1 root root 11 2009-06-22 16:45 firefox - firefox-3.. 0 lrwxrwxrwx 1 root root 32 2009-06-22 16:45 firefox-3.. 0 -.. /lib/firefox-3.. 11/firefox.. sh lrwxrwxrwx 1 root root 34 2009-07-01 21:17 firefox-3.. 5 -.. 1pre/firefox.. sh $ rm firefox $ ln -s firefox-3.. 5 firefox.. The newly installed version is branded Shiretoko.. That's the name used to identify 3.. 5 during development.. By using this technique, you're guaranteed that Firefox will get updated regularly through the Ubuntu package manager and that compatibility with system libraries will be preserved.. The downside of this is that you will get a little more updates than the average users: fixes to 3.. 5 will be dropped here first before they are made available to all.. As a consequence, it's not impossible that you will be among the first to find regression bugs..

The Acer Aspire One 110 is notorious for its small and sluggish SSD disk (SSDPAMM0008G1EA).. Firefox is so slow it seems web pages will never finish loading.. and you'd better not be in a hurry when starting the package manager or setiing up Ubuntu updates.. I wanted to find a solution that wouldn't involve tearing the motherboard apart and I found one.. It cost me about $40 and a couple of hours of work.. The idea is to use a fast SD card as the primary drive of the laptop by installing Ubuntu on it, the SSD becomes an extra storage device.. As you will see below, the SD card shows more balanced performances than the SSD and significantly faster write speeds.. I chose to buy the.. Transcend 16 GB SDHC Class 6 memory card.. Note that it is sold with  ...   hovering over a link with a tool tip.. That happens if compiz is in use and I verified the problem both on machines using Intel and Nvidia video cards.. The fix is easy:.. go to System - Preferences - CompizConfig Settings Manager - General.. uncheck Unredirect Fullscreen Windows.. intel.. Sun, 03 May 2009 18:38:00 GMT.. I ran into a major issue after upgrading an old Acer Aspire One netbook running Xubuntu to Jaunty.. It makes Xfce unusable especially if you have to login/logout or reboot frequently.. Fortunately, there is a workaround.. Symptoms.. The xfce desktiop takes minutes to initialize after the login windows.. As I login and logout a few more times, the delay increases and goes over an hour.. Similar symptom when running the update-manager.. Starting it up takes minutes/hours, the download and installation of new packages is equally slow and finishing up updates (when update-manager reloads it database) feels like it will never end.. While I'm waiting the HD light stays solid green.. Running.. pidstat.. while update-manager is working shows a high number of xfdesktop processes, very high IO activity, crazy context switching and reduced available memory.. Causes.. The Aspire One disk is extyremely slow, any swapping will make the machine slow to a crawl.. That's an aggravating factor.. But what seem to cause the issue is that I have configures Xfce to Save sessions on exit.. Apparently that causes the same processes (including xfdesktop) to be opened 2x, 4x and more every time an xfce session is started.. After a bunch of restarts, the number of started applications is just too high and the AAO can't keep up.. Workaround.. In Xcfe System Settings / Session and Startup , uncheck Automatically save sessions on logout.. And in the logout confirmation window, be sure to uncheck the Save sessions checkbox.. A bug has been filed in launchpad precisely on that problem and it suggests a workaround:.. Multiple instances of xfdesktop started simultaneously.. rm -rf ~/.. cache/sessions rm -rf ~/.. config/.. xfce4/desktop.. Then logout and login again.. The problem should go away.. xfce.. no comments.. Sat, 25 Apr 2009 22:49:00 GMT.. For situations where no graphical interface is available or when a remote installation is needed, the command-line distribution upgrade tool of Ubuntu can come very handy.. First you need to make sure the update-manager-core package is present (it probably already is).. sudo apt-get install update-manager-core.. Then all you need to do is run.. sudo do-release-upgrade.. If this command is run from an ssh session I highly recommend to run it inside of screen so that the upgrade won't stop in the middle of nowehere when the ssh connection is lost.. And be sure that the ssh connection will be lost at some point during the installation of the packages.. When you get back physical access to the computer, go to the console, 'screen -r' to get the upgrade prompt and answer the questions it still needs an answer for.. Note that this is NOT the recommended way for upgrades.. In my case, after getting access back to the computer, towards the end of the installation the display went completely black with no way of recovering it and I had to blindly reboot the machine assuming the upgrade was finished.. It turned out the upgrade did actually succeed but I might just have been lucky.. Note.. : this was tested for the intrepid to jaunty upgrade.. Thanks to.. sysblogd.. and.. lair.. moria.. for pointing me into the right direction.. adept.. upgrade.. Mon, 20 Apr 2009 01:54:00 GMT.. I started installing Jaunty on my computers 2 weeks ago.. The first one to get the honor was a new Acer Aspire One.. For this one as for the other ones, the install went flawlessly:.. the installer shrunk the windows partition automatically.. wireless was working after install (except on the all Aspire One with the Atheros interface.. Not resolved yet because of lack of time but it appears a solution exists:.. https://bugs.. net/ubuntu/+bug/350352.. graphics with 3D compiz effects were all working now using the 180.. 44 driver that got installed seamlessly.. After the initial install, I had some troubles.. Troubles with Ext 4.. No trouble with ext4 on the new AA1, the conversion worked, nothing to complain about.. It was a very different story on a Dell laptop of mine.. The conversion to ext4 succeeded there too, the machine rebooted fine after the conversion, but then I read a post about the need to append.. rootfstype=ext4.. to the kernel line in /boot/grub/menu.. lst.. I decided to go for it.. Big mistake.. Now, that was a really stupid idea.. I can't say for sure that's what broke it but in any case, the machine would not reboot after that, it would only go to grub console.. I tried reinstalling grub several times:.. boot with a live CD (I used a Jaunty live USB pen that I had).. go to the grub prompt by simply typing grub.. root (hd0, 5).. setup (hd0).. That rewrites the MBR with a brand new grub (supposedly supporting ext4 since it's 9.. 04).. That didn't help.. It wouldn't go past the grub console on startup.. No error message is shown.. The console sees the partitions, it even sees the files on the partition I want to boot from but it would not boot from it.. Trying to 'cat' a file from grub shows only garbage.. I also tried to repair the partition table just in case (using systemrescuecd and Test-Disk).. Nothing would help.. Fortunately, when booting from a live CD, I was able to mount the partition where I had my home directory so I could back it all up.. I finally resolved to reinstall the system entirely with a full disk repartitioning and reformatting and I restored the home directory from the backup.. That all went fine.. I had lost a crazy amount of time on that issue though.. So my recommendation is to not add that rootfstype=ext4 to menu.. At best it will change nothing, at worst it's going to kill your installation.. Boot time.. I measured the boot time before and after the upgrade and reinstallation on that Dell laptop.. The startup time is measured between grub and the gdm login page:.. Intrepid: 52s.. Jaunty after upgrade still using ext3 on the main partition: 46s.. Jaunty after upgrade after the ext4 conversion: 46s.. Jaunty after full reinstall from scratch (using ext3): 36s.. So, that's not quite what the hype tells us it is, it's merely an 11% boot time improvement from Intrepid to Jaunty and ext4 does not make any difference.. ATI, fglrx and xorg 1.. Jaunty comes with xorg 1.. 6 and ATI has not released a unix driver yet that supports it.. As a result, 9.. 04 does use the open source driver called just ati on machines using ATI video cards.. I was a little reluctant to upgrade on an old desktop with an ATI card because of that.. I'm not a Quake player but I didn't want to lose the compiz effects.. But it the end, this open source driver works wonders, the 3D effects appeared just as smooth as on intrepid and the CPU usage actually appeared lower while playing videos.. I don't think I will swittch back to the ATI fglrx proprietary driver!.. 6 comments..

  • Title: Category nvidia, everything about nvidia
    Descriptive info: 27.. Sun, 01 Mar 2009 03:27:00 GMT.. Another nasty side effect of using compiz with an nvidia video card is the screen flickering.. Right when a compiz 3D effect kicks in or 30 seconds after it, the screen goes black for a fraction of a second.. This is not a new issue, I have struggled with it since hardy and it happens with all nvidia driver versions I can remember (173, 177 and 180).. Cause.. The cause the is the Powermizer feature of the nvidia driver.. It adjusts the.. GPU.. speed depending on the usage that is being made of the desktop.. Every time Powermizer decides to change the frequency, the screen flickers.. You can easily verify that by going to the Nvidia X Server Settings panel, Powermizer.. Watch the Performance Levels and see how the level changes every time the screen flickers.. Solutions.. There are many related posts on the web.. The most common solution that gets reported is described for example at.. Linux Outlaws Forum.. Add the following lines to /etc/modprobe.. d/options:.. options nvidia NVreg_RegistryDwords='PerfLevelSrc=0x2222' options nvidia NVreg_Mobile=1.. It didn t worked for me in Intreprid or older Ubuntu releases.. So the real solution that does completely works for me is to freeze the powermizer performance level to 0 through the Nvidia X Server Settings panel in the Clock frequencies pane.. But that panel is only available after setting the Coolbits option in /etc/X11/xorg.. conf in the screen section.. For example, this is what I have:.. Section quot;Screen quot; Identifier 'Default Screen' Device 'nVidia Corporation G72M [Quadro NVS 110M/GeForce Go 7300]' Monitor 'Generic Monitor' Option 'AddARGBVisuals' 'True' Option 'NoLogo' 'True' Option 'RenderAccel' 'True' Option 'Coolbits' '1' Option 'RegistryDwords' 'PowerMizerLevel=0x3' Option 'AddARGBGLXVisuals' 'True' DefaultDepth 24 SubSection 'Display' Depth 24 Modes '1680x1050'  ...   desktop.. It brings the end user experience up to the MacOSX level.. Unfortunately it sometimes comes with nasty side effects.. On my Inspiron 6400 with a 7300 video card, it started misbehaving in Intrepid with driver 177.. Window titles would either disappear or get painted with weird pink stripes.. It happens only sometimes and only with a few applications.. It may happen when the focus switches from one window to another or just when typing.. Thunderbird is the application where it happens the most.. The definitive test is to start a new email and type the subject: the titlebar of that window will systematically get corrupted.. It s really ugly when it happens.. Nvidia driver version 177 is clearly the worst.. Reverting to 173 improves things a bit but it still won t pass the Thunderbird compose email test.. You can easily switch to 173 by going to System/Administration/Hardware Drivers.. But today, as I was experimenting with the newest nvidia driver, 180.. 29, everything got fixed.. Big thanks to Nvidia for fixing this!.. How to setup the 180 driver in Ubuntu Intrepid Ibex?.. I followed the instructions in.. Adam Michael Roach webpage.. Basically, do the following: Append those 2 lines to /etc/apt/sources.. list:.. net/anders-kaseorg/ppa/ubuntu intrepid main deb-src http://ppa.. net/anders-kaseorg/ppa/ubuntu intrepid main.. and run the following commands:.. com 026491A5DD081BDC6CDFC0DE6298AD34413576CB sudo apt-get update sudo apt-get install nvidia-glx-180.. Reboot and you re done:.. me@myhost ~ $ dmesg | grep -i nv [ 16.. 183016] nvidia: module license 'NVIDIA' taints kernel.. [ 16.. 438964] nvidia 0000:01:00.. 0: PCI INT A - GSI 16 (level, low) - IRQ 16 [ 16.. 438974] nvidia 0000:01:00.. 0: setting latency timer to 64 [ 16.. 439174] NVRM: loading NVIDIA UNIX x86 Kernel Module 180.. 29 Wed Feb 4 23:44:25 PST 2009..

  • Title: Tag ubuntu, everything about ubuntu
    Descriptive info: Mon, 24 Nov 2008 03:47:00 GMT.. laptop_mode is an extremely poorly documented tool that is distributed with Ubuntu and it's also a dangerous one as it is either the cause or the solution for the very widespread problem of the hard drive spindown issue.. It's so poorly documented that nobody seems to know it it's in use or not in Ubuntu.. It's also very difficult to figure out how to turn it on or off.. Once this issue is figured out, laptop_tools can be very convenient to configure how your laptop saves power.. But unfortunately its interactions with other tools designed for a similar purpose are problematic to say the least.. Here's is what I managed to figure out by experimenting and going through various posts on the net.. What is laptop_mode anyway?.. laptop_mode is a tool with a set of configuration settings to configure your block devices, the frequency of the CPU, when to turn off the display, all in one place.. For all disks on your system you can configure things such as.. are the disks mounted witth noatime, relatime?.. APM (Advanced Power Management).. using write cache.. All those things you can already set using hdparm and /etc/hdparm.. conf but the difference is that laptop_mode makes it possible to have different settings for different modes (on AC or on battery mainly).. For example you might want to sacrifice some of the performance of the disks to save some power but only when you're running on battery, not on AC.. laptop_mode files.. /usr/sbin/laptop_mode: the script that applies the laptop_mode settings when invoked by a power management daemon.. /etc/laptop_mode/laptop-mode.. conf: the configuration file where the power saving parameters can be set for various power states.. /proc/sys/vm/laptop_mode: current status of laptop_mode.. /etc/init.. d/laptop_mode: init script.. If called with the "start" argument, it may create "/var/run/laptop-mode-tools/enabled" and call "/usr/sbin/laptop_mode start" (see below why it may not do that).. How to tell what state laptop_mode is in?.. There is no laptop_mode process running in the background.. Instead laptop_mode is run when needed when the environment changes, it does what it needs to do and exits immediately.. /proc/sys/vm/laptop_mode has the current status of laptop_mode:.. 0: disabled.. 2: enabled.. I've never seen it at 1.. If the status is enabled, then the appropriate settings found in laptop_mode.. conf will be applied as soon the power state of the machine changes.. How to turn it on?.. "/usr/sbin/laptop_mode start" will change the status to enabled.. "/usr/sbin/laptop_mode stop" will change the status to disabled.. That always works.. The problem is to figure out if laptop_mode will automatically be invoked during startup.. There are several conditions that need to be true for that to happen.. d/laptop_mode must be executed by default during initialization.. That is the case in 8.. 10:.. me@myhost ~ $ ls /etc/rc?.. d/*laptop* /etc/rc0.. d/K99laptop-mode /etc/rc3.. d/S99laptop-mode /etc/rc6.. d/K99laptop-mode /etc/rc1.. d/K99laptop-mode /etc/rc4.. d/S99laptop-mode /etc/rc2.. d/S99laptop-mode /etc/rc5.. d/S99laptop-mode.. However that's not enough.. Looking closely at /etc/init.. d/laptop_mode, we see:.. # FIXME: this shouldn't be configured there if [ -f /etc/default/acpi-support ];  ...   will be entirely ignored if laptop_mode is enabled.. That's because hdparm settings are applied very early during the boot process by /lib/udev/hdparm and laptop_mode runs later overwriting whatever disk settings may have been set in hdparm.. What about ACPI?.. laptop_mode, if in charge, also overrides ACPI settings related to hdparm APM (Advanced Power Management).. This is visible in /etc/acpi/start.. d/90-hdparm.. sh.. if [ -e /usr/sbin/laptop_mode ] ; then LMT_CONTROL_HD_POWERMGMT=$(.. /etc/laptop-mode/laptop-mode.. conf echo "$CONTROL_HD_POWERMGMT") if [ "$LMT_CONTROL_HD_POWERMGMT" != 0 ] ; then # Laptop mode controls hdparm -B settings, we don't.. DO_HDPARM=n fi fi.. Unfortunately, this is bogus because, as we've seen above, laptop_mode may very well NOT be enabled even if laptop_mode.. conf exists and CONTROL_HD_POWERMGMT is non zero.. If that happens then no one will take care of tuning the hdparm power management when switching between battery and AC.. See.. ubuntu-hdparm-apm-and-laptop-mode-tools.. for more details.. Note: this got fixed in Intrepid in an update mid-January:.. acpi hdparm fixed.. But anyway, if laptop_mode LMT_CONTROL_HD_POWERMGMT is found to be 0, ACPI is in charge and controls the APM settings (-B) between 128 (battery) to 254 (AC).. What a mess! As for me, the poorly managed interactions with ACPI and udev/hdparm convinced me to turn off laptop_mode once and for all.. Thu, 13 Nov 2008 02:58:00 GMT..
