I recently updated to Ubuntu 22.04 and that seems to have solved the issue.
Hello I sometimes get a black screen when using my laptop. Everything else (sound, etc) works but the screen goes black. It only happens when I'm using the built-in screen, never happens when using a connected screen. I'm using Ubuntu 20.04.4 LTS and querying the journal with "journalctl -o short-precise -k -b -1" shows: kernel: i915 0000:00:02.0: [drm] *ERROR* CPU pipe A FIFO underrun Anyone has any idea what causes this?
