I have exactly the same problem on an IBM X40.

[Andrey Yurovsky (andrey.yurovsky)]

I have the same problem on my ThinkPad X40 (same chipset as reported in this bug), it's reproducible by either a suspend/resume cycle or by leaving the laptop idle long enough to where the backlight is turned off. I can confirm that this is a regression introduced by 9.10, this was working correctly in 9.04.

[FreeMinded (pascal-planetmages)]

plus 1 for ThinkPad X40. Was no issue in 9.04.

tschentz, thank you for reporting this bug to Ubuntu. Karmic reached EOL on April 30, 2011.
See this document for currently supported Ubuntu releases: https://wiki.ubuntu.com/Releases

Is this reproducible in the latest release of Ubuntu via http://cdimage.ubuntu.com/daily-live/current/ ?
