Description Bruno Pio 2009-05-22 14:40:58 UTC

glxgears -info makes 1432.313 FPS in exa and 1474.754 FPS in uxa, but 3D programs did not work or very slow, like google earth in exa and uxa in Intel Corporation Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller [8086:27a2] (rev 03) and sometimes the desktop turn off in uxa.

Could you elaborate:
how google earth does not work? (the same with exa and uxa?)
desktop turn off?

google earth acts as if in 1 fps, holding the images to a few. Even opening another program, file or folder, Google Earth is still on top as a black screen flashing... other programs that use 3D are the same. In both exa as uxa.

The Desktop, sometimes, is in uxa as the monitor came in idle mode and is off, having to move the mouse to turn on, even at times when I'm in the middle of work.

Never quote glxgears numbers for any reason.

Could you update your Mesa and 2D driver to the current versions in xorg-edgers?  We've fixed a bunch of issues related to vblank syncing since then.

updates solved the problem.
