Description of problem: Whenever I try to start any OpenGL app on this system, the screen freezes as soon as the app's window appears (presumably the instant the OpenGL surface is created). If I ssh in, I can see that the "Xorg" process is using 100% CPU. I can kill -9 it, causing the screen to go black, but I can't get X to work again without a reboot. The card in question is a Matrox G400 32MB. I tried it at both 16 and 24 bit color depth, with the same results. Version-Release number of selected component (if applicable): mesa-libGL-6.5.1-7.fc6 xorg-x11-server-Xorg-1.1.1-47.fc6 xorg-x11-drv-mga-1.4.2-1.fc6 How reproducible: Every time. Steps to Reproduce: 1. run glxgears or enable compiz Actual results: Screen is frozen until system is rebooted.

This problem is likely fixed in mga driver 1.4.4 according to https://bugs.freedesktop.org/show_bug.cgi?id=8666 I'll build that version from source tarball and report results here.
OpenGL is working under 1.4.4 so far. The only problems are that the mouse pointer disappears and/or leaves a trail of corruption when moved over an OpenGL surface, and the right side of the screen isn't rendered properly when using compiz at 1280x1024. IIRC the former problem dates back to FC3 or earlier, and the latter is probably a 1024x1024 texture size hardware limitation, so I see no obvious harm in updating FC6 to the 1.4.4 driver.
1.4.5-2 (resync with rawhide) is headed to fc6-u-t now.
Pushed to fc6-updates. I assume it worked, since no one complained...
Since updating to FC6 on a system with a Matrox Millenium G200 card, the X-display is unusable (I tried several Monitors) -- the problem appeared already during the boot from the FC6 iso CD. -- the display is grainy and can hardly be read, particularly at 1280x1024.
Hope the update to xorg-x11-drv-mga-1.4.5-2.fc6 will help (I will test the machine later today)
