Bug Description
Binary package hint: gnome-power-manager
I'm using a Dell Inspiron 700m laptop. Whenever I plug in the power cord, and whenever I unplug the power cord, the computer immediately goes to sleep. (I'm pretty sure it's sleep, and not hibernate.) I tried debugging the problem by monitoring the output of the following commands, but nothing appeared to change during the plug/unplug event.
upower --monitor=detail > upower.log
dbus-monitor --session "type='
These commands were recommended for debugging gnome-power-manager on the g-p-m web site.
Here is the output of those commands:
upower:
Monitoring activity from the power daemon. Press Ctrl+C to cancel.
[14:41:20.290] daemon changed:
[14:41:29.566] daemon changed:
[14:41:52.508] daemon changed:
dbus-monitor:
signal sender=
string ":1.57"
It may also be worth noting that in order to get this version of Ubuntu (10.04) to work at all on this laptop, it was necessary to create the file, /etc/modprobe.
options i915 modeset=1
Without that workaround, the laptop boots up to a blank, unresponsive screen. Ubuntu 8.04 had none of the above problems.
Thanks for looking at this bug! You folks are great!

While looking for a fix, I ran into this thread that seems to confirm the problem in Ubuntu 9.10:
