With Ubuntu 9.10 Karmic Koala Alpha 6 (i386) and with most recent updates for today wont my laptop Asus X51R run on battery if it uses GUI, non GUI mode seem to work fine as far as I can tell. What happens if I unplug the AC connection in gnome while not using the computer is that the computer will lock and become unusable it's almost like it's lagging. To get around this problem is a hard reset needed and that the AC is plugged in again, neither ctrl+alt+f2, ctrl+alt+backspace, ctrl+alt+del work.
I'm unsure where to look for information but in the syslog did I find this, unsure if it's related to the problem

Problem confirmed.
This problem appear with Kubuntu 9.10 beta on i386.
Without KMS - freeze in stage loading KDE.
With KMS - freeze when moving to kdm from accelerated console. Looks like some problem related to graphics.
Problem show up less, when X running in shadowfb mode.
When is unplugged cable when system running, sometimes remain OKey (for while), somethime do screen corruption and then freeze (no logs, nothing)
In this moment I can't provide any logs, because I'm not direct user of this laptop...
