[Bug 535653] Re: Lenovo Thinkpad x100e System freeze during X start-up and while X is running, but only on battery.

[Brian Candler]

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?
