[X1400] Problem with X if no power supply

[Bambitroll]

I upgraded to Intrepid recently and noticed that X did not behave properly when I did not have the power supply attached to my Thinkpad T60.
The symptoms:
- if I boot the machine without the power supply attached, X never starts. I just get a dark screen and I get a "[fglrx] ASIC hang happened" in the syslog
- If the machine is up and running and I remove the power supply, X dies and get just full of grey dots.
- The but is a bit similar to https://bugs.launchpad.net/fglrx/+bug/197209 even though I do not experience problems with suspend/resume.
- All works fine if I have a external screen attached.
- All works fine if I do not use fglrx as a driver but use the open source one.
- I have the problem only if I use xorg-driver-fglrx 2:8.552 (from Intrepid-proposed)
- Works fine with xorg-driver-fglrx 2:8.543 (the default Intrepid one)

I have a Thinkpad T60 with an ATI X1400 graphic card.
Kernel is 2.6.27-11
I attached the relevant part of my syslog.

Here is my xorg.conf

And the result of a lspci -vnn

I would like to stress again that the problem is only with xorg-driver-fglrx 2:8.552 from Intrepid-proposed.
All works fine with xorg-driver-fglrx 2:8.543 (the default Intrepid one).

try this work around:
sudo aticonfig --auto-powerstates=off

and yes, i'm having the same problem on my T60
and this problem also exists with 2:8.561 direct from ATI

Thank you for reporting this bug about fglrx, however the video card mentioned in this bug report is no longer supported in fglrx. ATI only supports R600 and newer chips. You'll want to focus on using the -ati driver instead for this hardware.
