[SOLVED] Wayland hangs after login

Like the title says, after putting my login credentials inside the SDDM screen and going into Wayland the splash screen shows and after that

the screen freezes completely, leaving me only with the background image and the mouse in the middle, but the system still works despite

this freeze, i even played some music in Spotify just to make sure, this does not happen in X11.

My current setup is a HP Omen 16 laptop with AMD 6800H and a Nvidia RTX 3060
I'm not sure what other info i could put here, if needed just ask lol

Re: [SOLVED] Wayland hangs after login

+1 here.
I'm currently trying to figure out which packages have to be downgraded to get it working again.
In the meantime, XFCE+X11 has to take over...

Re: [SOLVED] Wayland hangs after login

So, plasma works again.
Navigate to /var/cache/pacman/pkg to downgrade the packages.
Here is my downgrade-list:

pacman -U pyside6-6.10.1-2-x86_64.pkg.tar.zst
pacman -U plasma-integration-6.5.5-1-x86_64.pkg.tar.zst linux-6.18.6.arch1-1-x86_64.pkg.tar.zst vulkan-radeon-1:25.3.3-2-x86_64.pkg.tar.zst

Hope it helps.

Re: [SOLVED] Wayland hangs after login

I would say: yes
I did not have to downgrade ddcutil, I still have

ddcutil 2.2.5-1

installed.

AND xfce on wayland did not work either, BUT it worked with X11.

Re: [SOLVED] Wayland hangs after login

I mean, I could upgrade all packages again and downgrade ddcutil, just to see if it has the same effect.
I'll report back when I have a result...

Re: [SOLVED] Wayland hangs after login

Iff it affects plasma AND xfce but only wayland, the most likely offenders would be vulkan-radeon and wayland-protocols

Re: [SOLVED] Wayland hangs after login

I just upgraded all packages again and interestingly, my plasma desktop still works.
BUT the onboard laptop screen seems to be frozen, external monitors (HDMI and USB-C->DP) work.

Downgrading ddcutil did not change a thing. Laptop screen is still frozen.
After closing the laptop lid and opening it again, all screens (including mouse pointer) is veeeery laggy.

Re: [SOLVED] Wayland hangs after login

Ill try the downgrade thing.

One thing to note is that the issue reproduces in x11 when i enable compositing.

Re: [SOLVED] Wayland hangs after login

Yup! Downgrading ddcutil to the version 2.2.3-1 solves the problem, wonder why that happens.
