SDDM not working

thesun · 2023-12-14 16:35:49

Hello, I'm having an issue on arch: When I turn the PC on, GRUB works normally, arch boots, but, on a black screen with a _ on the top left and the cursor, instead of loading sddm like it normally does, nothing happens. And after a few seconds, mouse and keyboard stop working. This happened on the first reboot after moving my config files to here. I have installed on the pc cava, kitty, nitrogen, polybar and picom. There were already installed on it i3, kde, openbox, gnome, and hyprland.
I moved to it the config files for cava, kitty, nitrogen, polybar, i3.

Also, SSH works if I put in username and local ip. the usage seems to be really low. CPU is idling at about 0-1%.

The pc specs are xeon x5650, quadro fx 580, 8gb ram, 500gb ssd,

Can someone please help me? Thank you.

edit: I uninstalled SDDM using SSH, now it's not even getting past Loading initial ramdisk ...

Likely a crash in nouveau. When did this start? After a kernel update? Which? Can you restore functionality when downgrading to a known good kernel?

After "crashing" and sshing in, what's your output for

sudo journalctl -b

This started after I moved the .config files of cava, i3, kitty, nitrogen and polybar to the PC. Everything worked fine. Then I shut off. I turn it back on and it has this problem

I can't access SSH anymore, the OS won't even boot at all anymore after I tried to remove SDDM

Btw I installed trough archinstall

Try to boot the multi-user.target, in doubt along "nomodeset" (2nd linke below)
Then post your complete system journal for the previous boot:

sudo journalctl -b -1 | curl -F 'file=@-' 0x0.st

If this doesn't work, you'll have to fix the system offline, ie. eg. from the install iso.

Here's the output to the command.

Do you have xf86-video-nouveau installed?

pacman -Qs nouveau

(try to remove it)

You could still try the 340xx drivers, https://wiki.archlinux.org/title/NVIDIA … ed_drivers

thesun · 2023-12-15 15:38:16

Pacman -Qs nouveau gives out no output, and pacman -R nouveau says it can't find it

seth · 2023-12-15 15:46:50

The complete package name would have been xf86-video-nouveau.
If you don't want to use the 340xx drivers you could resort to the LTS kernel and hope that a future mesa update fixes this or try your luck w/ the xf86-video-nouveau driver

Oh, and

Dec 14 16:55:20 thesun kernel: simple-framebuffer simple-framebuffer.0: [drm] fb0: simpledrmdrmfb frame buffer device

Enable https://wiki.archlinux.org/title/NVIDIA … de_setting and in doubt add "initcall_blacklist=simpledrm_platform_driver_init" to the https://wiki.archlinux.org/title/Kernel_parameters (it doesn't matter that you're not using the nvidia drivers, it's just a hack to get rid of the simplydumb dummy device)
