Experiencing the same maybe once every two weeks for about two years now. When tabbing in or out of Chromium, the GUI freezes. The mouse cursor moves, but clicking does apparently nothing. The keyboard works: space bar to pause/resume music if a player was focused, as well as switching to a virtual terminal. I can log in there and kill X / restart gdm3, but the GUI session is lost.

SSH access works. This is on Legion Y545, Ubuntu 19.10 Nvidia Geforce 1660Ti Intel 9750h Symptoms: This only happens when: Nvidia-Prime is selected as "on-demand" And maybe most likely after the laptop comes out of sleep. xserver-xorg-video-intel is the latest :: 2:2.99.917+git20190815-1 If I choose prime-select "nvidia", this never happens. Makes me believe this has to do with intel video drivers.
