I am happy to say that I found source of my problems. DRI2 module. As long as I start Xorg with "Disable DRI2" in module section I have normal picture and I have normal smooth rotatin of the gears in "glxgears" test. Output of the "glxgears" without dri2 module: 565 frames in 5.0 seconds = 112.932 FPS 559 frames in 5.0 seconds = 111.726 FPS 558 frames in 5.0 seconds = 111.590 FPS 554 frames in 5.0 seconds = 110.797 FPS 569 frames in 5.0 seconds = 113.742 FPS XIO: fatal IO error 11 (Resource temporarily unavailable) on X server ":0.0" after 6301 requests (36 known processed) with 0 events remaining. Output of TOP: 1676 vas 20 0 15784 4868 1760 R 52.6 0.3 0:03.75 glxgears 1032 root 20 0 53664 12m 7124 S 39.9 0.8 0:50.63 X With DRI2 module i had no more then 20 FPS and unstable gears rotation. Of course there is no H/W acceleration, bu there is no eyes problem and good picture. My fault, I installed too many "freetype" on Fedora. |
