I have ThinkPad Z61t with intel graphics. Sometimes when computer is left idle it crashes and GDM restart.
This happens in up-to-date Gutsy Gibbon. Xorg.0.log.old ends with:
ProcXCloseDevice to close or not ?

I can confirm this with a Dell Inspiron 1420, running Gutsy, except that the computer completely freezes and it has to be turned off with the power button. My Xorg.0.log.old ends with:
