I just built a new system and installed F10-KDE from the Live CD. The CD refused to boot into full graphical/install mode so I used text install.
It looks like the system now freezes when there are certain graphical applications being run. glxgears always makes the system freeze. I'm sure there are others, but this one is easiest to test.
Interesting tidbits: * glxgears runs smoothly for a second or two before the freeze. * there's a bit of very faint high-pitched whining (apparently from my video card) while glxgears is running. Not sure if that's normal. Never had problems with this card before, though. * SysRq/REISUB doesn't work. I've tested it without the freeze and it works like a charm, then.
Hardware: Q6600 Asus P5N7A-VM ATI X800 GT (X800PRO)
There's no xorg.conf, X automatically recognizes everything. According to Xorg.0.log, ati/radeon driver is used. I've tried creating xorg.conf with system-config-display (no effect), and tried setting it to radeonhd (my videocard is not supported by it). Can't try fglrx, as it's not available yet...
What is the next step, if there is one?
Thanks, Konstantin
