X fails to start when IBM TP T22 is on battery

[Braden Obrzut]

After installing Kubuntu 8.10 my T22 laptop fails to boot while on battery. It will pass the Kubuntu splash screen however afterwords it will only show a black screen. The laptop will boot just fine if plugged in and has full batter power and if I unplug it while it is booting it will also start just fine.

Besides the black screen the system still shows signs of running normally.

Hi blzut3,

Please attach the output of `lspci -vvnn`, and attach your /var/log/Xorg.0.log file from after reproducing this issue. If you've made any customizations to your /etc/X11/xorg.conf please attach that as well.

To add to the report. When the problem occurs apparently the computer completely freezes (I thought hitting the power button made it shutdown, but it seems I did hold it down for 5 seconds). I also did not see the problem happen while booting into xfce, but I'm going to confirm this and report back.

As an additional note I have the computer set to auto login.

Xfce vs KDE does not make a difference so my second guess is the battery level needs to be about 90% for it to fail. I think I was able to get it to boot while it was failing by going into failsafe, dropping to root, executing "shutdown now", and then canceling when the menu came up but I can not reproduce this.

You may find this of use in narrowing down the cause of this issue a bit further:

Unfortunately I have reinstalled 8.04 about a week or two ago since this laptop was going to be used by someone that knows next to nothing about using computers, so I needed something I knew would work. As a result, I can not perform further tests.
