Plasma Wayland Session Fails to Start

Fast forward to April 2025, brand new Tumbleweed install, this is still happening.
X11 session works fine.
Logging in as Wayland fails.
But from a tty startplasma-wayland works … what the heck does that show?

Have you tried a different user?? may be a config problem

@mrmazda Interesting comment? (from the original topic - refer link above)

Lets see what I have;

I do have another system with older Intel iGPU I could pop a Quadro P400 in… but it will work…

Well oddly, I discovered that once I did the startplasma from a command line, it started working without having to do that i.e. I could choose plasma-wayland on the login screen. Doesn’t explain that after a fresh-install it did NOT work.
I made a bit more progress, I created a new user, using the UI.
When I tried plasma login, did not work.
I rm’d the .config directory for the user, then wayland started working.

This would oddly point to some “template” that created .config is conflicting with wayland somehow.

Made 10 months ago!!! How did this old thread manage to not get locked after 7 days or 30 days from last post?

You are the dual graphics with NVidia wizard. You know all the traps to avoid. Also, I think the common BZ instances I referred to involve laptops and their unique power conservation needs, not workstations. OP’s Dell 5521 is a laptop. Amaxware didn’t tell us what hardware he’s using.

I’ve split this discussion away from the original topic, which is now closed. We don’t yet know which graphics chipsets are in use, and in any case the user’s plasma settings seem to be a contributing factor here.

@amaxware can you please show the output from inxi -GSaz

@mrmazda Ahh did not notice… lot has changed since then!!!
