Всем привет!!
У меня проблема с экраном - разрешение и мерцание при прокрутке. Я кажется нашла решение всех проблем, но не могу перевести на русский((
Будьте терпимы ко мне))

Вот что я нашла:
1. X.Org - first thing you see is distorted and slow Xorg. it uses default driver(vesa, I guess) and Poulsbo driver should be installed separately. Fortunately, it's easy:
* - add the following line at the end of /etc/apt/sources.list: deb
http://ppa.launchpad.net/ubuntu-mobile/ppa/ubuntu jaunty main
* - execute the following commands from command line:
* sudo gpg –keyserver keyserver.ubuntu.com –recv 0×99d6b21cc6598a30; sudo apt-get update;
* sudo apt-get install xserver-xorg-video-psb
* I also installed libgl1-mesa-dri-psb_0.25-0ubuntu1~810um1.1_i386.deb from
http://ppa.launchpad.net/ubuntu-mobi...-mesa-dri-psb/ manually, cause didn't find it in repository Packages list.
* Restart the system(or restart X and 'modprobe psb' before) and it nicely will bring 1366x768 with basic acceleration.
* Here is glxgears output:
* $ glxgears
1153 frames in 5.0 seconds = 230.592 FPS
1171 frames in 5.0 seconds = 234.018 FPS
1165 frames in 5.0 seconds = 232.928 FPS
1154 frames in 5.0 seconds = 230.570 FPS
2. I noticed hangs a few times - mouse was moving, but all the system freezes. My guess is about CPU temperature - I installed sensors applet to check and I'm almost sure that this freezes are connected to the CPU temperature raising. After googling, I saw the acerhdf module(which responsible for fan and temperature control for Acer Laptops) was added in 2.6.30, and installed the kernel from Karmic Koala Alpha, which is 2.6.31-rc3. I did a stress CPU load and saw the temperature raising, but system works well. Anyway, I can't be sure, cause the other possible reason is the psb-driver, which has proprietary binary code and could be the problem as well. But the psb kernel module doesn't compile on kernels > 2.6.28 yet.
UPD: I've made a patch to allow psb kernel module work with 2.6.31-rc3, but the system still hangs, and seems the problem in the PSB X.Org module
So, I will try to make it work and hope it will not take too long to wait until the GMA500 will be supported at 100%.
I don't need a 3d on the netbook, but the web-browsing speed is slow.. And it's definitely the problem of video driver, not a CPU. Default mplayer(with -vo xv and framedrop=soft) plays regular divx/mpeg4 movies very well, and I'm able to play even 720p HD clips(not movies) - and this is without hardware acceleration enabled. As for the last, I followed this steps:
http://gwenole.beauchesne.info/en/bl...i_accelerationbut it doesn't work for me yet - the newly built mplayer fails on -vo va. Will try more a little bit later.
A few most relevant logs attached, maybe it will help someone.
