Trying to figure out why my screen just rapidly turns off and on after returning from a screen saver. It’s like the computer is returning to screen saver or returning to sleep. How do I go about troubleshooting this? It wasn’t doing it when I first installed the OS a few days ago but started after doing some updates.
I have the same issue, I’ve been hard headed, not making backups before updates. This is this last time I will do an update on an arch based system without backups. Reinstalling the os didn’t work to solve the issue.
I temporarily disabled my lock screen and that seems to have mitigated the problem for now. It would be nice to use a lock screen again though.
It looks like it’s specific to the lock screen function. I disabled all power savings features and the problem persists if I leave the lock screen enabled. As soon as I remove the lock screen feature the problem goes away.
When this happened to me, I simply typed my password and hit Enter. Lightdm gave me an error message (wrong password)…but also stopped blinking. I re-entered my password and logged in successfully. Workaround, but not a solution. Hoping for a fix in a future update.
