Public bug reported:
Binary package hint: gnome-power-manager
Some bug in Jaunty causes a ThinkPad to suspend immediately after
resume, twice, after being suspended. I'm using Linux 2.6.28-2-generic
and g-p-m 2.24.0-0ubuntu12 on a ThinkPad X61 Tablet. To reproduce:
1: Press Fn+F4 to suspend, then immediately
2: Close the lid.
3: Open the lid. The system will resume to the login dialog, but then
immediate suspend again.
4: Hit the Fn button to wake it again and it will resume properly.
I hypothesize that the lid close is queued as a "suspend" event even
though the machine is already headed for S3. Then when the machine
wakes, the lid close event is processed, which suspends it a second
time.
I would recommend that all pending events ought to be ignored after one
suspend action is received. Or, the event queue should be cleared upon
resume. Either way, this is a classic race condition.
