I don't believe the problem is X's fault because it does not occur in GDM's graphical
login screen even if I leave the computer in this state for days; neither can it be the
kernel's fault because it does not happen in console mode (i.e. without GDM and X). It
only occurs in a graphical user session.

I attach my /etc/X11/xorg.conf.
I'll test some things to narrow down the list of suspects:
1. GDM configuration settings --- I'll leave the computer on not in GDM's login screen
nor while I'm logged in in GDM but in a newly created default user's session
2. power management (although I'm not using this)
3. the window manager
Of course, I am open and grateful to any suggestions.
