I’ve got two monitors, an Acer and a LG. I did a full system update with sudo pacman -Syu
earlier today, and after reboot, my LG monitor is going black every second or so (not a full power off, just the screen as if it’s having trouble rendering). My Acer monitor is perfectly fine, and both monitors were working pre-update.
Edit: I’m noticing that it seems to blink less often if there’s no mouse or keyboard input. It will blink for some time after keyboard input has stopped, but will eventually calm down?
Edit 2: Changing the resolution to something else besides 2560x1440 seems to have stabilized the LG monitor. Changing it back to 2560x1440 causes the blinking to happen again.
Edit 3: I’ve disabled the Adaptive-Sync option in my LG monitor’s settings menu (GSYNC-compatible FreeSync) and the blinking has gone away. Seems like something in the update broke compatibility with it. While I can make do with this disabled for now, it’s not ideal. Is this a known issue with FreeSync and is there a fix for it?
Any help is appreciated.
I’ve tried:
- Changing the refresh rate of the LG monitor from 144Hz to 60Hz, but no dice
- Upgraded kernels from 5.4.231-1 to 6.1.12-1, but it’s still happening
Any help would be appreciated because this is a very annoying issue. Thanks.
