Public bug reported:

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='signal',interface='org.freedesktop.PowerManagement'" > dbus-
monitor.log

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=org.freedesktop.DBus -> dest=:1.57 serial=2 
path=/org/freedesktop/DBus; interface=org.freedesktop.DBus; member=NameAcquired
   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.d/i915-kms.conf, and insert the following text:

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!
