Also getting this with a zBook 15 01:00.0 VGA compatible controller: NVIDIA Corporation GK107GLM [Quadro K1100M] (rev a1)
With both nouveau and nvidia drivers. Ctrl-alt-F1 , ctrl-alt-f7 workaround unlocks things.. This seems to happen more when browser windows with lots of images are open. Is it related to these messages from dmesg?
