Something is configured for X, I think.

@hellomiakoda as others have mentioned, there may be multiple things going on, which can be different to troubleshoot. Since you mentioned the drivers are dropping support for your chipset, maybe doing something like

pacman -Q | grep nvidia

And then manually installing the version that had been working will get your GUI working again.

[hellomiakoda@pdx.social]

@ktneely It appears the driver issue is probably resolved. I had to install 580. Right now, it seems SDDM is trying to run on X, and Manjaro removed X... so no sddm. I can't get sddm going.

[ktneely@infosec.exchange]

@hellomiakoda I'm not familiar with SDDM, you could install another DM, or it looks like there's some experimental Wayland support out that you have to enable/install: https://wiki.archlinux.org/title/SDDM#Wayland

[hellomiakoda@pdx.social]

@ktneely I was wrong, it doesn't seem to be using the nvidia drivers at all. Ok, back to focusing on that. God damn it, what a fucking mess

[hellomiakoda@pdx.social]

@Unlikelylass Open source drivers seem to be loading no matter what i do... and they're not working.

[hellomiakoda@pdx.social]

@hazelnot I GOT IT!!! I HAVE SDDM!!! Thank you! Though, your suggestion is incomplete. I needed linux618-headers, THEN nvidia-580xx-dkms, along with additional nvidia-580xx packages. BUT, what you said started me on the path that lead me to it working again!

[hellomiakoda@pdx.social]

Alrighty! I got it working again! @hazelnot's suggestion was incomplete, but got me down the right path.
First, I needed linux618-headers (or whatever kernel you're using)
THEN nvidia-580xx-dkms
as well as
nvidia-580xx-utils
nvidia-580xx-settings
lib32-nvidia-580xx-utils

The following also got installed, but unsure if necessary or had any effect.
opencl-nvidia-580xx
libxnvctrl-580xx

@hellomiakoda @hazelnot@sunbeam.city I was going to recommend going the opposite direction and seeing if the nouveau/nvk open source driver was an option, but I'm not sure what the status is on that particular card.

[markus@hubzilla.markusgarlichs.de]

@Miakoda :neurodiversity: this should fix the issue - install the nvidia-580xx-dkms and nvidia-580xx-utils driver from AUR.

[hellomiakoda@pdx.social]

@markus Yes. I found I also needed linux618-headers

[oblomov@sociale.network]

@hellomiakoda two paths I see are: drop the proprietary driver if mesa has decent enough support for your card, which should allow Wayland to work; or install a WM that still supports X11 and use that instead of KDE.
