I think I am experiencing the same bug - * Thinkpad X60 (logs attached) * Ubuntu Hardy updated as of today - crash happened last time yesterday * Started happening some time in the hardy upgrade cycle * Upon crashing, the screen flickers like on startup of X (backlight is turned completely off for a moment etc) * It seems xorg is trying to restart, but won't. Have tried killing xorg remotely and restarting. Does not work, must reboot - very annoying. * GNOME, No desktop effects enabled * No apparent reason for crashing, but seems to happen often when I run "heavier" OpenGL applications (tuxracer, wine/directx) * "Lightweight" OpenGL applications work (my own homemade app has been running an entire night without crashing) * It also happens when I (to my knowledge) do not run OpenGL at all. I can be just moving the cursor reading a web page in firefox, and suddenly it crashes. * The caret/cursor disappears, the x server is really trying to restart. * No artifacts on screen. Turns black (and I can see the backlight switching on/off/on) * Can not switch to text ttys with ctrl-alt-f1 after crash. * I CAN reboot with ctrl-alt-del, but there is nothing on screen * Ubuntu Shutdown splash screen shows some times after ctrl-alt-del, but not always.
