Frozen gdm login and blank screen [solved]

drossbox · 2024-07-20 13:07:09

Hi all, hoping someone has a bit of time because I have no idea how to fix this.

Hybrid nvidia/Intel graphics setup which has been working fine for a long time. Suddenly the laptop screen is only blank with a flashing cursor, and if I plug in the HDMI output on the back of the nvidia card I'm shown the gdm login screen but it greys out and freezes after entering my password.

Here is my journalctl -b

Reading a few other posts I've deleted any sign of an /etc/X11/xorg.conf to no avail. I also tried rolling back everything in case it was nvidia-dkms to how it was a month ago but that didn't work either strangely.

I've then spammed lots of things I don't even remember and almost certainly made it worse lol. Any advice on where to go next much appreciated!

EDIT: AND TRY A NON-HARDENED KERNEL!

That's w/ the nvidia-settings generated config…

Jul 20 13:47:00 Thinkpad /usr/lib/gdm-x-session[1898]: (II) NVIDIA(0): Validated MetaModes:

Jul 20 13:47:00 Thinkpad /usr/lib/gdm-x-session[1898]: (--) NVIDIA(0):     option

but looks unsuspicious. It'll however make you run on the nvidia chip and disable the intel one (hence the need to attach the monitor)

Please post a journal w/o the xorg .conf.

looks sketchy. Are you running partial updates?

pacman -Qikk gdm gnome-shell gnome-session

FFS, I'd run nvidia-xconfig after removing the conf hadn't worked.

No partial updates AFAIK - I've only ever run -Syu? Is there any chance I've excluded things from updates in the past because of gdm-prime?

I'll mark as solved even though I have no idea why, because I reinstalled gdm on the off chance and it now works lol.

Thanks for taking the time.

I'd run nvidia-xconfig

Don't and remove the config again, it'll only make things worse.

Is the "Dropping signal SessionOpened of type (s) since the type from the expected interface is (ss)" message still there?
