[RESOLVED] GDM Issues (Fedora 42)

I've recently been unable to use my computer running Fedora 42 with gnome. It boots up, and GDM starts running, however it shows a flat grey screen with no login option. I can pull up a tty and login as normal (although using gnome-session to start a GUI session from there doesn't work). I have tried to use systemctl to restart GDM from the tty, but that l brings me back to square one. What can I do from here to resolve this issue?

GPU: Radeon 7800xt, Open Source Drivers Window System: Wayland.

if you're savvy enough to know about gdm, you're savvy enough to know to include at least some details, like what graphics you're running, X11/Wayland, etc.

Edited to include now

UPDATE: Resolved, it was an issue caused by a faulty display port cable. Different issues from this cable had happened recently, I just initially assumed it was a software issue due to the fact that only GDM was affected.

Can you mark title as resolved?

Last time I had a similar-ish issue it was some graphic card drivers failing. Ones I didn't even need nor could use but somehow ended installed. Check the log from the boot sequance. Generally its Linux - you'll find answers in some log.

Or just purge and reinstall GDM. (your expiriance may vary)

Logs, as in what shows up in journalctl? Also, when you suggest purging and reinstalling gdm, what issues are you saying I might run into?

I'm not up to speed on GNOME, not a fan of it, but can't you just try a different DM? like SDDM? would that work? seems silly that GNOME would lock you into their DM.

It would work, but likely only as a temporary fix. Unless I intend to switch away from GNOME permanently, I'd be unable to lock my screen, since GNOME uses GDM specifically for screen locking.

eesh, that would be a deal breaker for me.

Have you tried booting from an older kernel? When I was on Fedora I had things like this happen from time to time and would always go back to one of the archived kernels and wait for another update.

Will likely roll back in grub on the next boot. Thanks for reminding me I can do that
