Good news everyone! Indeed, it seems that the problem is kernel crashing! If you start Kubuntu normally and log in, while starting KDE/whatever you switch to console (Alt+Ctrl+F1) and close the lid you'll see something like:
[<timestamp>] BUG: Could not handle a NULL pointer reference in kernel. Ok, If someone knows how to trace this somehow, it'd be great! I wonder why wont the kernel panic in that event... Your proposition of unloading button.ko might not be the problem -- I haven't seen the source but sounds like a pretty simple module. I guess the next step is to get someone interested in this problem .... Someone who knows how to debug or at least get a trace out of this. -- Gusty crashes when the lid is closed on a HP 6710b https://bugs.launchpad.net/bugs/157691 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
