set up x and vaapi accelerated hd video on the msi wind u110 gma500 poulsbo and ubuntu karmic 9 10 saturday december 26 2009 the following guide is now slightly outdated as ubuntu 10 04 is out and new drivers are necessary also some of the repositories i originally used have disappeared if you use ubuntu 10 04 try following my much easier directions here instead the largest detriment to the ubuntu 9 10 driver is a complete lack of suspend to ram for me i will leave my guide for 9 10 online as reference though it seems to have been the first good description and i m happy about the major online media coverage i ve finally managed to get it running here is what i did first you need to get ubuntu 9 10 running with poulsbo the first steps 1 4 describe how to set up the driver for x the second part 5 10 describes how to set up vaapi and mplayer to get video acceleration there is already an early stage gma500 driver for ubuntu 10 04 the image shows the phoronix test suite benchmarking when i play grey ts in a loop loop 0 with mplayer and vaapi but without sound nosound on my netbook during the entire time the cpu frequency is also downscaled to 800 mhz compare to phoronix vdpau benchmark on a core 2 duo system which obviously shows even less cpu usage because the cpu is much more powerful or the atom and nvidia ion benchmark on phoronix cpu usage when playing a 10 minute fireworks recording in 1080p 50 fps without sound and then two fullhd movie trailers the cpu is clocked at 800mhz the entire time the spike is caused by a bug in my test sequence i didn t start a new mplayer process for new files but passed them all at once on the command line i can watch fullhd 1080p 50 fps ac3 videos with about 30 or less cpu utilization atom 800 mhz on my netbook now looks really nice too some videos produce artefacts especially self recorded avchd m2ts files if you use the right demuxer avchd videos play fine but deinterlacing does not work sometimes the video seems not to run very smooth etc it s not perfect yet don t expect too much but most videos work perfectly no matter what resolution the only real problem is with suspend to ram you can t use suspend to ram or vaapi at the same time if you used vaapi and try to suspend the system doesn t suspend and or crashes if you suspend then use vaapi or even xv i think the system crashes really hard so suspend doesn t really work as expected yet i think the sound also doesn t work properly after suspend suspend works fine for me even after resume if i do a double console switch ctrl alt f1 wait until you see the console then ctrl alt f7 here s what you need to do 1 basically you add the gma500 repositories for ubuntu 9 10 karmic and 10 04 lucid to etc apt sources list d mobile list if the entry below doesn t work check this page sudo add apt repository ppa gma500 ppa sudo apt get update 2 then you install the poulsbo driver 3d including the firmware and everything 2 a check if you can load the psb module sudo modprobe psb if you see this in dmesg instead of a switch to the correct resolution kernel bug unable to handle kernel null pointer dereference at null 2 6 31 you need a manual hack to get the driver working as i just reported 3 once that s done for a more stable and speedy operation you need to add an etc x11 xorg conf section device identifier gma500 option accelmethod exa someone suggested uxa but that s for the i965 drivers option dri on option migrationheuristic greedy option ignoreacpi yes driver psb endsection section dri mode 0666 endsection 4 reboot and make sure that it works if x doesn t work properly yet vaapi won t either after a short black screen you should be greeted in the correct resolution full screen xv video should already work fine suspend to ram also worked perfectly at this point for me if the system goes to dpms standby and from there switches to other modes dpms suspend etc then my screen actually turns on again showing all black with backlight active so make sure you chose only one setting for dpms a constantly running screen is not good at all vaapi video acceleration setup now comes the part where we install the hardware decoding acceleration if you just want x you can stop now this is written for ubuntu 9 10 with old repositories so 5 6 might not be necessary anymore or work for ubuntu 10 04 5 install the libva library from http www splitted desktop com gbeauchesne libva pkgs i386 libva1_0 31 0 1 sds8_i386 deb this replaces your current libva1 with a newer version also works for me don t forget to install the dev version http www splitted desktop com gbeauchesne libva pkgs i386 libva dev_0 31 0 1 sds8_i386 deb as well if you want to compile mplayer later wget http www splitted desktop com gbeauchesne libva pkgs i386 libva1_0 31 0 1 sds8_i386 deb http www splitted desktop com gbeauchesne libva pkgs i386 libva dev_0 31 0 1 sds8_i386 deb sudo dpkg i libva1_0 31 0 i386 deb 6 create a link of your video driver to the vaapi driver directory sudo ln s usr x11r6 lib modules dri psb_drv_video so usr lib va drivers a precompiled setup you can alternatively skip to part b compiling the source code setup 7 download and unpack the precompiled mplayer http www splitted desktop com gbeauchesne mplayer vaapi mplayer vaapi 20090914 i686 tar bz2 8 install a normal mplayer and libmad with apt get sudo apt get install mplayer libmad0 9 unpack mplayer and create necessary links to the libraries it expects ldd mplayer tells you what library names mplayer expects just to go usr lib and create links to them e g ln s libx264 so 67 libx264 so 65 this should work as long as your libraries are newer than the expected ones it may actually work out of the box in ubuntu jaunty 10 start mplayer from the package you downloaded e g mplayer vaapi 20090914 i686 mplayer fs vo vaapi va vaapi hdtest avi b compiling the source code i ve also manged to get the source code to work this is less bothersome because you need not link the libaries hence less man hours but more disk space and computer hours for compiling didn t take as long as i feared though and it s using a slightly newer version of mplayer vaapi which includes some rudimentary osd in vaapi mode now 7 install the build environment sudo apt get build dep mplayer sudo apt get install libdrm dev wget http www splitted desktop com gbeauchesne libva pkgs i386 libva dev_0 31 0 1 sds8_i386 deb sudo dpkg i libva dev_0 31 0 1 sds8_i386 deb maybe sudo apt get f install 8 download the source at http www splitted desktop com gbeauchesne mplayer vaapi mplayer vaapi 20091106 full tar bz2 unpack it and execute the checkout patch build sh 9 check if it works e g mplayer fs vo vaapi va vaapi hdtest avi 10 sudo make install x done enjoy e g a nice hd trailer for a start post your results i can recommend using it in smplayer for more comfort e g automatically continue where you left of last if it crashed check out by blog entry about smplayer crashing in vaapi mode update it turns out deinterlacing not working is not due to vaapi but a limit in the psb driver it works with the current iegd driver and other drivers from amd and nvidia press the d putton in mplayer i think if i could just get one of those iegd drivers thanks gwenole from splitted desktop com for answering my email and of course for writing the mplayer vaapi patches in the first place he seems to be the absolute vaapi expert also some experiments show that i can attach an external screen and watch videos with vaapi on it that means i should be able to actually use the netbook for decoding hd video and displaying it on an external screen but it does not work for me with except in mirror or single display mode only thing missing now is a digital display port to connect a fullhd display you might also be interested in surround sound and battery life and i did get a usb surround sound card working wonderfully now also here s some advice i wrote on decreasing your power

edid then reconfigure the package and it should be recompiled the next time you start it it should work instead of creating kernel bug update xvideo actually works better than in directx video in windows xp where i often see blocky video scaling the cpu usage is not too high either currently it s only working under ubuntu 9 04 for me though i had managed to compile the module with kernel 2 6 30 before i don t remember how i did that and i haven t gotten actual video acceleration to work yet of course i ll keep you updated and i ll post a little howto once it s all working but feel free to ask anyway and thanks so much to the person from the ubuntu bugzilla who helped me to finally get it all working update2 keep checking the page i will post a link to an archive with a script that will manage the compilation in ubuntu 9 10 if someone could help me figure out how to i d love to create upload and post a deb for dkms so it all works automatically or ultimately we could modify the driver to check for the msi s signature and then skip the edid check i ve created a package for karmic that you can use to manually install the driver with the fix already applied http www megaupload
