Hi there, I've just built graphics stack (xf86-video-intel, libdrm, mesa) from git (but I'm on 2.6.35.x kernel) and still experiencing vsync troubles without composite manager, here's output of glxgears:
$ glxgears Running synchronized to the vertical refresh. The framerate should be approximately the same as the monitor refresh rate. 243 frames in 5.0 seconds = 48.124 FPS 157 frames in 5.0 seconds = 31.300 FPS 155 frames in 5.0 seconds = 30.864 FPS But I'm pretty sure that vertical refresh is 60 hz! And gears are jerky (not smooth at all). If I move mouse cursor over glxgears window FPS goes up to 60. And main problem is that keyboard events are also jerky, i.e. I press key and system receives press event in 0.1-0.5 sec or so (tested via xev). There's no such problem when composition manager is running (i.e. effects are enabled in KDE) Is there any solution for this problem? It really annoys me. Regards Vasily
