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.
No matter what, whether I tell it to sleep or never sleep or dim or never dim, when I come back from work, the screen is black and I have to force reboot.
If the monitor goes to sleep or is turned off, the screen is black and off when the monitor is turned back on
I have to set my power savings to not turn off the screen or allow the computer to go to sleepo - otherwise i have to force a reboot with the power button.
Same issue you are all describing. In fact, same hardware that chaosngn mentioned. I am on Manjaro Arch Linux with Kernel 6.12 using Plasma + Wayland. I thought it was fixed in Plasma 6.3.5 with the lock screen freeze, but that did not help.
Not sure if it’s the same issue but I wasn’t getting display output after resume and even switching TTY didn’t fix it. I searched and searched and was about to give up when I turned to Copilot and asked it.
Answer was given right away in the first set of things to try. Much as we might grumble about AI taking jobs and whatnot, it got me past a wall of "I have the same issue"s and did a great job.
Although the systemctl command you mentioned didn’t do it for me, I never thought to try switching TTY. Lo-and-behold! Ctr+Alt+F3 brought back my screen! F1, F2, F4 didn’t do it, but F3 was it. So, thank you for that nugget!
Same issue. Doesn’t matter what distro or GPU I run. My htpc has an AMD GPU and previously had a Nvidia GPU. Same behavior. I pull up a tty but it’s annoying, I don’t have this issue with my desktop monitors. Manjaro, cachy, vanilla arch and even pop! Os.
