gdm: Waiting for idle screen blank makes gdm widgets unresponsive to any input
Affected version
F36, mutter@26790f7f, gnome-shell 6b60a189, gdm-41.3-3.fc36.x86_64, mesa 22.1.0-0.3.20220222.05.7ec8a32
Bug summary
Waiting for idle screen blank makes gdm widgets unresponsive to any input. You can move the mouse around fine but nothing reacts to mouse or keyboard input. One way to fix it is to switch to a different tty and back.
Steps to reproduce
- Boot your PC
- In gdm do nothing until screen blank
- Move the mouse
Relevant logs, screenshots, screencasts etc.
There's this in the journal at around the screen blank time (I think), not sure if related:
