I’m not sure what’s the issue here.

I’m on 43.20251216 and it was working fine for days, but today I can’t login and there’s just a black screen. I’ve tried to reboot but still the same problem. It’s really strange since there haven’t been an update or anything that could broke it.

systemctl restart sddm.service makes SDDM appear but if I reboot it doesn’t come back.

I’ve just rebooted and it’s working fine again, not sure why 😕

Edit : I’ve lost my SDDM settings. (The numlock key is now disabled when I set it to be always enabled).
