I'll assume you're running XFree4 since you didn't say otherwise. X freezes like this for me quite frequently. Branden claimed it was a kernel bug some months ago, but that was fixed and it still dies. A number of things cause it, but I never knew DRI to be one of them. Mozilla caused my uptimes to be measured in hours rather than weeks under recent XFree4 packages. With my new card (ATI Radeon) it's changing video modes (which anyone who has seen me work in X knows I spend 30% of my time in 640x480 or lower due to unreadably small, aliased fonts in things like Netscape..) The problem seems to be in short that damned near anything will cause X to lock up and stop responding. A suggestion to make your life a little easier is to renice XFree86 to 0. For some reason it gets -10 by default amd that's just pleading for a lockup to down the box if you don't have a convenient box to ssh in and fix it. > The only way to recover from this is to login to the machine over the network, > kill -9 X, and restart it (which, in my case, is done by gdm).

Switching back to X works fine though (ie, it repaints > the screen and otherwise behaves normally). You can fix this by using the framebuffer console for your card. Except that most framebuffer drivers are not quite stable (like XFree4 it would seem) and very slow. > For this reason, I've disabled DRI on my system until this problem gets fixed. > It would be nice to have it fixed, since applications like blender get really > slow without it... > > My hardware is a Creative 3D Blaster Banshee.

I can reproduce it with XawTV, Ctrl-Alt-Grey+, and any DRI app which uses the VidMode extension. I can also do it with anything that creates shaped windows frequently (the OSD plugin for XMMS for example or some window manager themes) In short, it's really easy to get X to freeze. -- Joseph Carter <[EMAIL PROTECTED]> Free software developer <Kethryvis> Gruuk: UFies are above and beyond the human race :)
