Unable to login into plasma wayland on KDE 6

Help

1

After upgrading to KDE Plasma 6 on openSUSE I have some problems with login.

On login screen when I select “Plasma (Wayland)”, I can type in my password, but after I press Enter everything just freezes, my mouse cursor disappears, and I can’t even enter tty using CTRL + ALT + F1 or F4. The only way to unfreeze is to reboot using magic sysrq.

However, I can still login into X11 session without any issues.

This is my hardware:

xset:  unable to open display ":0"

Already tried:

  • Modesetting nvidia gpu using nvidia-drm.modeset=1 (was configured like this even before upgrading);
  • Installing libnvidia-egl-wayland1 (was installed along with the system update)
  • exporting DISPLAY=:0 (does nothing)

Thanks in advance

After a couple of days, I was finally able to solve the problem (kinda). Changing the default shell from fish to bash fixed the problem (many thanks to sugar_in_your_tea from lemmy for pointing out this problem in their post). I still don’t know why this is happening, but I’ll try to send a bug report to the fish developers.
Marking this as solved.

I was having the exact same problem as described in the first post - after upgrading to latest Opensuse Tumbleweed snapshot 20240315, which also installed plasma6 - and replacing fish with bash using chsh solved the problem; I can now login and use Wayland.
Thanks for sharing the solution; also, do you have a link for the bug posted at fish dev?

It appears to be more of a problem on the SDDM side rather than the Fish side. You can read more about it here & here
