Is there any way to configure shutdown on critically low battery to give me a bit of time before actually shutting down?
I've set GNOME Power Manager to shutdown on low battery (hibernating does not work on my netbook). Problem is, I don't get any notification about battery running low, and as soon as battery level reaches the critical threshold, the system quickly kills applications and shuts down without me having any chance to quickly complete some tasks and/or save some data. Of course, I'd increase battery level thresholds to gain some more time to accomplish such tasks.
If some other window manager has a more advanced power management facility than GNOME, I'm also willing to switch.
