Hello everyone,
I’d like some help troubleshooting a weird issue I’m having.
The problem
At startup, after grup menu, when using kernel 5.10 or 5.11, booting stops after gdm service starts, and a grey screen with a blinking horizontal cursor shows up (as can happen when gdm is about to start) but stops there.
This does not happen using LTS kernel 5.4, which is a good thing.
Also, when the bug occurs, I can still open a tty.
What happened just before
I updated my system via the command line using sudo pacman -Syu. Rebooted for unrelated reasons, then the bug happened.
