Hm, it is actually working now. Closing the lid, choosing suspend in the logout menu and in the gpm tray icon all work. (To answer the question, I have that lock file).
I'm a bit confused as I did try several times yesterday, and rebooted to make sure all updates were used. I wonder if my mirror was out of sync slightly so that not all updates were included. I will keep testing this over the next days and see if I can get it to fail again. If you want to close this bug, I can just reopen if I manage to reproduce it again. -- Recent patch to change suspend to use gnome-power-manager breaks suspend on ibm x41 https://launchpad.net/bugs/44430 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
