[SOLVED] "Something has gone wrong" on the GDM login

After an upgrade, I cannot log in my GNOME session using GDM anymore. There is a white screen saying "Oh no! Something has gone wrong.".
I have tried to repair it using a USB medium and arch-chroot to access the system, but I had no luck so far. This what I have tried so far:

- Remove nvidia-open and nvidia-utils packages, as I have had some problems with NVIDIA drivers recently.
- Update microcode using

mkinitcpio -P

- Add the following in a `~/.xinitrc` file

export XDG_SESSION_TYPE=x11
exec gnome-session

- Force X11 by disabling Wayland: setting WaylandEnable=False in /etc/gdm/custom.conf
- Reinstall `base base-devel linux gdm gnome_shell gnome_session` packages by first deleting the pacman cache and then using

pacman --cachedir /var/cache/pacman/pkg -S --dbonly base base-devel linux gdm gnome_shell gnome_session
pacman --cachedir /var/cache/pacman/pkg -S base base-devel linux gdm gnome_shell gnome_session

- Reinstall all packages using

pacman -Qnq | pacman -S -

A problem I see is that `uname -r` and `pacman -Qi linux` have mismatching versions: 6.8.8 and 6.9.6, respectively.
EDIT: Actually, when not using the live medium with chroot and using the non-GUI login in the system, the version correctly match.

Also there are two log file I found in /var/log/:
- /var/log/Xorg.0.log: http://0x0.st/XmNQ.txt
- /var/log/Xorg.0.log.old: http://0x0.st/XmNj.txt

Any help is appreciated. Thanks!

Re: [SOLVED] "Something has gone wrong" on the GDM login

So I found the problem. It was the mutter-performance package, which substitutes mutter. Uninstalling it and reverting to mutter solved the problem. Also explains why reinstalling all system packages was not working; this is an AUR package.
Maybe something went wrong during the build of mutter-performance last time I updated it and it trigger this issue.

Re: [SOLVED] "Something has gone wrong" on the GDM login

You've a hybrid graphics system and are running the modesetting driver on the IGP - there's no obvios problem in the xorg log.
Please post your complete system journal for the boot:

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

to see what has "gone wrong" ( … gnome)

Thanks for the reply, Seth. I think we crossed messages though. The problem is now resolved
Unless you still wanted me to post the logs (which may be lost for that session)? Thanks again anyways!
