>From the other bug (this is getting a bit tiring): I was able to trigger the crash pretty easily with the old library still in use by opening and closing the lid a few times in quick succession and then trying to type an update to this bug. After restarting I was not immediately able to trigger it, but instead brought gnome-shell down with an assertion (g_malloc failed to allocate 1.8x10^19 bytes). Working down the stack a few frames it looked like it was trying to use an invalid structure, presumably in memory which had already been freed. Which at least raises the possibility that gnome-shell has some memory use bug which triggers on suspend and resume and that libinput was collateral damage.
I am thinking of rebuilding gnome-shell with memory debugging enabled. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1724259 Title: gnome-shell frozen and using 100% CPU after docking and display configuration change Status in gnome-shell package in Ubuntu: Incomplete Bug description: I have been having regular system freezes after switching from using my laptop stand-alone to waking it up on a docking station with an external monitor. I have seen this using two identical docking station plus monitor combinations. I am still trying to find a pattern. I was able to ssh in and use apport to save this bug information. The gnome-shell process was hung at 100% CPU utilisation.
