Comment 6 for bug 1958591

Good morning,

Chiming in to say that I am experiencing the issue exactly as described.

Going into lock screen or leaving the device idle (no mouse or keyboard input for about 1 minute) is enough to trigger this unique display error.

Here is a link to an unlisted YouTube video, 35 seconds long, showing the buggy display:

$ lsb_release -rd
Description: Ubuntu 20.04.3 LTS
Release: 20.04

as OP jamesf said, the internal display can only be recovered by a hard reboot.

Happy to help test solutions, thank you
