Cannot login through GDM

[zexy72]

I have OpenSuse Tumbleweed GNOME on my laptop.
It was working fine till yesterday. I was configuring some neovim files. Today I can’t login into the system. I enter the password, no error is shown, a black screen comes up and the login screen is shown again.

I did not do any updates nor messed with any system config files. It happened once before but I did not think much of it and did a clean reinstall. KDE used to work fine but I want to use GNOME. Any way to fix this?

Thanks.

EDIT: Snapshots do not work. Can’t login even in them.

From the GDM login screen, can you start a working Gnome X11 session? Any other desktop environment?

From a VT login in as a user and try launching Gnome using…
QT_QPA_PLATFORM=wayland XDG_SESSION_TYPE=wayland dbus-run-session gnome-session > gnome.log 2>&1

Does that result in a working graphical session? If not examine gnome.log for errors.

Found my mistake. I thought I did not edit any system files but I did. The mistake was adding exec zsh in my .bashrc file. I did a login through VT and it showed a msg for not even a second ( did a slo-mo vid) and found out that it showed -bash: exec: zsh: not found

SOLUTION: Open Advanced boot OpenSuse Tumbleweed (something something) from grub menu > boot into recovery mode > enter root password > vi /home/[username]/.bashrc or vi/nano into wherever your .bashrc is > remove the exec zsh line from .bashrc > reboot

Now that I know,I might have added exec fish in the previous install in which I was having the same issue.

Thanks @deano_ferrari for helping.

Thanks for the update. Yes, changing the shell seems to be a known issue with breaking the Gnome and KDE Wayland DEs.
