Custom login screen broke physical environment

After installing a custom login screen on KDE Plasma 6.1 on Arch linux, I am unable to login to my computer on the graphical environment.

Is it possible for me to be able to set my login screen to the default, or even be able to skip the login screen by using the TTY just so I can actually use my computer?

Thanks

Hi & Welcome!

Yeah, you can drop to a root shell promtp from the commandline to login. Try holding down CTRL + F1 or F2 and your interface should drop to a TTY.

Maybe remove that custom login screen when you can. Just an idea.

Hi, thanks for your reply!

So ive did what you said and logged in to the TTY but my physical environment is still blank with a text cursor and mouse cursor. Ive tryed some other things people said, too, but nothing is working.

Do you still have the .iso image of Arch Linux on USB or a DVD?

If so you can try booting into that Live and do what’s called chroot.
This way you can fix your broken system.

Is Arch Linux the only os on your machine?
You’ll need to find the device of the root partition and mount it.

That included editing /etc/sddm.conf.d/kde_settings.conf from the TTY command line, with your favorite command line text editor like nano or whatever you have installed, and change Current=.... at the [Theme] section back to Current=breeze ?
Of cause that only works if “custom login screen” means “custom sddm theme” if you have replaced sddm with a completely different greeter things get slightly more complicated.
