Created attachment 30531 [details] photo of distortion After switching from openSUSE 11.0 (with x.org 7.3) to openSUSE 11.1 (with x.org 7.4) I got problems with my Radeon 9600 - all screen is covered with vertically running waves, especially noticeable on sharp edges such as window edges, fonts, mouse pointer and etc. Such distortion is very unpleasant for eyes. Until now, I was using proprietary ati drivers which where fine, but now I had to switch to opensource drivers for obvious reasons. I tries to upgrade x.org, libdri, libdrm and kernel from openSUSE repositaries couple times, but it didn't help.

Doe it work better if you remove the custom modelines in your config or perhaps try a modeline generated with cvt or gtf? E.g., Modeline "1024x768_85.00cvt" 94.50 1024 1096 1200 1376 768 771 775 809 -hsync +vsync Modeline "1024x768_85.00gtf" 94.39 1024 1088 1200 1376 768 769 772 807 -HSync +Vsync You also might try switchin gto some of the other 1024x768 modes that you have defined.
Ok. With the first modeline that you suggested it works fine, but it is really more mensurable for eyes to work with 100Hz refresh rate on CRT monitor, so I tried to generate new modelines (modeline from my xorg.conf with working form me for years without any problems) with cvt and gtf: # 1024x768 99.97 Hz (CVT) hsync: 81.58 kHz; pclk: 112.25 MHz Modeline "1024x768_100.00cvt" 112.25 1024 1096 1200 1376 768 771 775 816 -hsync +vsync # 1024x768 @ 100.00 Hz (GTF) hsync: 81.40 kHz; pclk: 113.31 MHz Modeline "1024x768_100.00gtf" 113.31 1024 1096 1208 1392 768 769 772 814 -HSync +Vsync Both producing same distortion as I described in my initial post. Then I switched back to your modeline ("1024x768_85.00cvt") to get good screen and then tried to switch to 800x600 mode with systemsettings from kde4 (it's really annoying to restart X every time, moreover it is refuses to start after two restarts and I have to reboot my computer). In 800x600 mode screen is also distorted. Here is a modeline from xvidtune: "800x600" 56.30 800 832 896 1048 600 601 604 631 +hsync +vsync After switching back to 1024x768@85 it works fine again. P.S. I'm sure that my monitor and videocard is fine as it was working fine in 1024x768@100 mode for years in Linux and still working fine in this mode in Windows. So it's really desirable to get back 1024x768@100 in Linux.
It was a hardware problem with bad capacitors on motherboard. Why there wasn't a distortion in windows is still a mister though.
