2 near identical laptops: one suspends happily, the other hangs
Binary package hint: gnome-power-manager
I've got two HP Compaq nx6110 laptops, both installed from 9.10 release candidate and now running the final Karmic. On a fresh install, both laptops suspended, hibernated and resumed happily. I've since installed wicd and acpitool on one of the laptops and it no longer suspends or hibernates - it just hangs on a blank (but backlit) screen, power light not switching off - i.e. not entering sleep state.
With the exception of wicd replacing NetworkManager on one of the laptops they're pretty much identical.
How can I debug whether wicd is the culprit and/or whatever else I might have done to this system to break suspend? My only other alternative is to re-install from scratch again...
