Here is what I believe is happening: When my screen is turned off for a long enough time, my display goes in stand by mode, and it can’t recover an active screen afterward. In case the computer goes fully to sleep, this issue doesn’t come up.
Happening on HE with Legion Go (so no nvidia shenanigans going on) too. If the screen turns off due to inactivity in Power Management settings, the screen stays off even when it should wake up after activity was detected
What I have done to tide me over is adjust the Power Management settings to directly sleep after some inactivity, and only dim the screen instead of turning it off.
That does in fact sound a lot like the other thread that I linked to this one. I would assume it’s two different issues that come into play one after the other but I’m not quite sure.
