Problem:
Since upgrading to Ubuntu Hardy Heron every time the screen lid was closed on my IBM X30 the whole laptop would hard hang, only resolution was to reboot. No remote logins possible, no killing of the x-server, no switching to a new virtual terminal and worst of all no error messages or stack trace.
Resolution:
With nothing to go on other than a description I resorted to trawling launchpad for related bugs, tonights search brought up gold. Namely the following bug:
Bug #138256: laptop hangs on lid close unless ForceEnablePipeA option enabled
After applying the work around: Set the following option in your xorg.conf:
Section “Device”
…
Option “ForceEnablePipeA” “true”
EndSection
I can now close my laptop lid without having to reboot.
As per the bug listed above I have logged a new bug on launchpad for a proper fix:
Bug #288859: Need a Pipe-A quirk for 1014:0513
Hopefully this will help other IBM X30 Ubuntu users…
