New experiment: created /etc/X11/xorg.conf with the following:

Sections "ServerFlags"
Option "BlankTime" "1"
Option "StandbyTime" "2"
Option "SuspendTime" "3"
Option "OffTime" "4"
EndSection

with my copy test: after one minute the screen blanked and the network seemed OK, but within 20 seconds it had frozen, and a ctrl-alt-F1 completely locked up the laptop. So at least I can reproduce it much more quickly now :-)

Then I set BlankTime to 0 but left the other settings as they were. Strangely, nothing went wrong after 2, 3 or 4 minutes, but after exactly 30 minutes the machine dropped of the network. Again, moving the pointer brought the gdm screen back. [This time after entering my password it just stayed at the gdm screen - with greyed-out password shown - and wouldn't go further. I've seen that before though]

I'm not sure where the switchoff after 30 minutes came from - gnome perhaps?
