Cannot reach login screen

Desktop Environments Plasma

Hi everyone,

I tried changing my SSDM theme to something else, and now when I reboot I get a black screen and a mouse cursor. What is the easiest way to revert it back to default?

Thanks!

Came across this with a quick search, maybe try the last option and if you get back in revert the theme to default and then re-enable password login

Thanks. I was having a hard time finding the exact issue while looking around. I will give this a shot.

So I tried to set the auto-login parameter like they suggested, but Iā€™m still just sitting there with a black screen and cursor. I was able to create the file and reboot as suggested though. Is there a way to change the theme in the terminal screen?

Looking that up now, just came across this on the arch linux wiki and it may be helpful also

Blank screen with cursor, but no greeter shows

Greeter crashes if there is no available disk space. Check your disk space with df -h.

If disk space is not the issue, it may be due to a bug. Switch to another TTY, and then try loginctl unlock-session session_id or to restart SDDM.

I found a way around it.

I went into /usr/lib/sddm/sddm.conf.d/default.conf and found the location for the themes for sddm. I removed that theme directory and rebooted. I was greeted with a default login, signed in and re-applied the breeze theme.

Thanks again for you help!

Was just about to suggest this as it is what I just found, mark your answer as the solution too so it can help others in the future. Glad you got it working.

you should be able to edit /etc/sddm.conf temporarily with autologin enabled. Then it should work when you reboot

[Autologin]
Session=plasma

edit: too late obviously :wink:
