Cachyos hangs with two screens at startup (while installing medium starts with no problems)

Hallo all,

I have been using cachyos with satisfaction for three weeks. Yesterday it suddendly hanged at reboot (the only operation I had made was a ntfsfix -bd on a windows ntfs disk before that startup).

I have two screens, one Eizo photo screen and an old office screen.

I tried reinstalling cachyos, the installer works fine with Kde fully working.

Once installed the normal startup stops after a few lines.

When shutting down through the start button for a brief moment the cachyos initial screen reappears.

There was recently an update to our cachyos-kde-settings package which defaults SDDM to wayland instead of X11. Try to “Apply Plasma Settings” under SDDM settings.

If above solution does not work, you can remove the -settings package to restore the X11 backend in SDDM sudo pacman -R cachyos-kde-settings.

Also, please provide the output of printenv | grep DISPLAY, ideally with and without the settings package

Thank you. I will reinstall it with a different desktop manager, I guess this should suffice to have it working before applying your solution to Plasma.

I confirm that the problem was that update. I installed a fresh version with Lxqt and I added Plasma afterwards. I confirm that the stock kernel of cachyos is ideal for photo work. I can browse through my very heavy tiff files collections with a decent speed now, while with other distros it was a painful and slow work, with frequent freezes (gwenview and xnview are my viewers). Gimp is superfast and the g’mic filters are applied faster than ever.

Very interesting. I experienced the exact same thing. CachyOS has been the only distro that allowed my dual screen setup. But few weeks ago I started having issues. I was thinking it was something that changed in rhe kernel. But today after a massive KDE update my desktop is unmanageable, glitches , distortion and massive freezes. So clearly its a plasma / KDE issue with Nvidia I imagine.
So I’m now looking at lxqt too.

Quick update .I won’t migrate to lxqt just yet. I created a user just for testing purposes snd discover that the desktop was perfectly stable… So it’s just that my profile is colliding with the updates in KDE/Plasma.

Any suggestions on howto purge my settings as if I logged in for the first time. Without blowing away my entire Home folder ?

I was going to remove anything kde and plasma. Anything else ?
