Latest patches to Karmic cause laptop screen to blank randomly

[Michael Dundas]

Binary package hint: xorg

I have had Karmic running for a few weeks now, with no issues. An IBMThinkpad T42p, with an external monitor connected as well as the laptop screen. Recently, after the last Karmic update via the update manager, my laptop screen randomly just turns off. The attached screen is fine and if I depress Fn+F7 a few times (5) the screen will re-appear with all the apps, icons etc. untouched. If I am watching a video with say VLC, it will continue to run and you can hear the sound.

I have adjusted the screen saver and power management for both AC and battery power, turning off everything I can. Doesn't help. I have turned off gnome-power-manager via killall, still screen laptop will blank randomly. If however, I remove the power from the laptop (i.e.running on battery), then it stops, until I put the power back in, then eventually the laptop screen will blank again. So this could be apic or some other issue?

Just happened and I was tailing Xorg.0.log .... nothing appeared, till I did fn+f7 5 times to get things back. Then there was the attached output which is probably useless, just my pressing fn+f7 causing it, but thought I'd add. (after -----) is when I depressed fn+f7 x5

Updated to the latest packages available today for Lucid, still having same issue.

Michael Dundas, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:

apport-collect -p xserver-xorg-video-ati REPLACE-WITH-BUG-NUMBER

Please note, given that the information from the prior release is already available, doing this on a release prior to the development one would not be helpful.

Thank you for your understanding.
