Can't get into my DE anymore after nvidia/nouveau switch + other stuff

I made a mess of things, and I'd very much like to get my system back into a normal state. Here's a brief history of important events:

(1) About 2 weeks ago after a system update, I couldn't log into Gnome via GDM anymore (see topic). Thankfully I could still get into Gnome via 'startx', so I stuck with that for a while. Busy time, and no real fix was forthcoming.

(2) About 4 days ago after a system update, that didn't work anymore either. (Both monitors would just stay black, but with a thick white bar on the left side of the right monitor.)

(3) I switched from binary nvidia drivers to nouveau, in the hope that that would fix things. It did, sort of. I could use startx again, but my display would now freeze after a short time of use, with many nouveau related errors in dmesg. My bug report to freedesktop.org about this is most comprehensive.

I really need a functional PC right now. Short of an actual fix, I'd love to just roll back everything to the state it was a month ago or so. But no luck there either.

(4) I installed the nvidia drivers again, uninstalled the nouveau stuff, set my system to query the Arch Rollback Machine for a month ago, and did a `pacman -Syyuu --force`. GDM still doesn't work, nor does startx. Using startx, I get the following 'Xorg.0.log' (I remember getting the same errors during my earlier messing about):

Re: Can't get into my DE anymore after nvidia/nouveau switch + other stuff

did you follow the instructions from https://wiki.archlinux.org/index.php/NVIDIA

pacman -S nvidia nvidia-libgl # Add lib32-nvidia-libgl and nvidia-lts if needed

oh and reinstalling GDM is an option as well

pacman -S gdm

Yes, I tried all of that, I'm afraid. In fact, my latest action was a month-old downgrade of my entire system, which definitely included all of those.

- /etc/X11/xorg.conf
- /etc/X11/xorg.conf.d/20-nvidia.conf or any related files
- /etc/default/grub

Can also try to reinstall gnome-session

pacman -S gnome-session

Heh. Believe it or not, that helped me. :-)

As a part of switching to nouveau, I had to remove xorg.conf. When switching back, I didn't put back xorg.conf, since I remember reading that that file wasn't really necessary anymore. Even so, it's something I should have tried but didn't.

GDM is still broken. But I can log into Gnome again with startx, which will tide me over for a while until a real fix comes along.

Thanks! Have this!

And yes xorg.conf should be replaced with /etc/xorg.conf.d/20-nvidia.conf instead

I might try that, though now that I finally have my PC back I have some other work that takes priority for a few days. :-)

I'm using `nvidia-xconfig` to generate that file (I haven't had to tinker with it manually for years now).

The tool generates this 'deprecated' file. Should I just move its exact content to the new location?

yes move and rename the file leaving the content as is is fine
