Title:
[Lenovo ThinkPad X1 Carbon] Windows are moved unlocking screen
Status in linux package in Ubuntu:
Expired
Bug description:
I have an external monitor attached to my laptop and am using a
ThinkPad OneLink+ docking station.
I repeatedly have issues where if I lock the screen and unlock it,
windows return to the incorrect window (my laptop window). I also have
crossed out icons (red circle with a line through it) for several of
my icons in the upper left corner of the screen in the toolbar).
I see the following in the kern.log:
