I'm running without KMS on my desktop machine, and that's where I get freezes when I use OpenGL apps (not otherwise). As stated earlier, this is an Intel 82Q963/Q965 rev 02. This system is x86_64 with an Intel mobo. I used to have frequent OpenGL freezes (everything dead except the mouse) which I reported at https://bugzilla.redhat.com/show_bug.cgi?id=510948. The problem seemed to go away with a kernel update, to kernel-2.6.30.5-32.fc11.x86_64, but now seems to have returned in kernel-2.6.30.5-43.fc11.x86_64 and kernel-2.6.30.8-64.fc11.x86_64,
Hm, I have seen recently random total freezes of that sort (everything is dead, including a network, and no traces of anything anywhere) while running xscreensaver-gl* pieces on Fedora 11 desktop machine but with radeon graphics driver. So maybe this is some nasty interaction between OpenGL and recent fc11 kernels instead of an intel driver fault?
Could be. I was surprised when the kernel update fixed the problem, at least temporarily, expecting it to be more an xorg-x11-drv-intel thing.
I tried remote access several times before the kernel 2.6.30.5 update and ssh was working at that time. There was no way to kill Xorg or get to runlevel 3 but the shell worked and I could run reboot. I assumed kernel corruption of some kind. I haven't tried it again with the more recent updates.
Turning off specific xscreensaver-gl executables (sometimes one sees leftover image fragments on a screen indicating an apparent offender) was of no help.
I use a simple screensaver, and I'm not getting any freezes except when running OpenGL apps.
