Problems with Nvidia and GDM.

the cocoa · 2025-10-12 17:54:53

Wasted 4+ hours with ChatGPT and Gemini and still not getting anywhere.
I have an external SSD that I am booting multiple OSes from. Ubuntu and Mint load without error.
ArchLinux won't boot to a login screen.

I know my hardware is good (Mint and Ubuntu show this).

Posting in the newbie channel because I am an ArchLinux newbie.

Any tricks for other people trying to get GDM and Nvidia to work together?

Cinnamon - presents a login dialog. I login and the login dialog reappears. Never make it to the desktop.
Gnome - (same thing)
Gnome on Wayland - (same thing)
Gnome on Xorg (same thing)

Which nvidia GPU? after an attempt at logging in, switch to a VT and post

sudo journalctl -b | curl -F 'file=@-' 0x0.st

That's a partial log from the install iso.

Yes, I'm reinstalling Arch Linux - that's probably why it shows a partial log from the install iso.

Ok, but that's useless - we'll need the data from the misbehaving system once you're there (and re-installing will usually achieve nothing, certainly not if you replicate the previous configuration)
