I have a Thinkpad P1 Gen 3. I am using the video-hybrid-intel-nvidia-prime graphics drivers and sometimes after waking the laptop from suspend, the screen will remain blank. I can get the display working by pressing
"loginctl list-sessions" and then
"loginctl kill-session" to force the X-Session to restart, and everything works again.
I have had a look at the Arch wiki for the P1 and the similar X1 Extreme, but I can’t find anything. Does anyone have any ideas what might be wrong?
