Yes, @rugyada placed the instructions in that thread.
I see what I did wrong. I told you task-plasma-wayland when I should have told you task-plasma6-wayland. 100% my fault for leaving out the ‘6’. Yet my installation shows I have task-plasma-wayland installed.
I had to think about this for a bit. I suspect the discrepency is I have Rome and you have Rock installed. A few weeks ago, the Rome repositories were updated, with everything containing ‘plasma6’ changed to ‘plasma’ when support for Plasma 5 was deleted on Rome.
From the SDDM login screen, are you able to boot into Plasma X11 or Failsafe X session? If you can log into either of those, then it should be possible to either figure out what Niri is doing, or just uninstall Niri to see if you can get back into the Plasma Wayland desktop environment.
I never messed with Niri. But it is for times like this that I am glad I have both Plasma and LXQt installed.
i tried reinstalling from the original usb that worked last time, and then tried to do a switch to wayland, but forgot to update first- then had a bootloop issue in login.
No idea (I’m a KDE Plasma guy), but I would assume it is also a victim of the Xorg → Xlibre switch. You simply can’t be running Xorg when the switch happens. It crashes and halts the update in the middle, leaving the system in a bad state.
Also, the XFCE spin is community-driven, and doesn’t get nearly as much attention as the Plasma version. My advice would be to grab a Plasma Wayland ISO, do the install, and even on Wayland, do a Ctrl-Alt-F4 to drop to a terminal to do the update.
All versions of OMLx beyond Plasma6 and Gnome are experimental, meaning they are alpha or beta. To fix problems with any of them you need to engage with the maintainer of that version, if there is a maintainer. That is a lot more likely to happen on OM-Chat than in this forum but you never know. Even with Gnome if you have problems you need to be talking with @AngryPenguin. I do not know who does XFCE.
Edit: Aside: I really, really, do not like these threads with to many different problems brought up. I would strongly suggest closing this thread and opening a thread with a descriptive title with the current problem and all the info you can manage to provide. There are multiple reasons we keep asking users please, please, only one issue per thread. Otherwise other users will not be able to find discussions of a real problem because it is buried in a thread about with an unrelated title.
For what it is worth, I installed Rome 4419 on my old laptop, did a system update, rebooted, then installed Niri, and rebooted. It worked. But I don’t have Nvidia, only boring old Intel from 2012. I was then able to log out and go back into Plasma. Then back into Niri.
