sddm login failed

Hi all,

I have been rushing my install ( i know never clever), I was going for the KDE desktop install and when reading the wiki saw Plasma 5 is the new way to go so thought I would give it a go, all going fine until I installed SDDM. I had created a user but forgot to set the password, now I cant figure out how to quit sddm return to the console and login as root so I can set the password. Any help  appreciated.

Re: sddm login failed

The easy way is to simply hit CTRL-ALT-F1.
This should bring you to a nice tty-prompt.

For explanation: There are by default 6 TTY's active (F1-F6). If X (graphical interface) is started by a display manager it is usually reachable on F7.

You could also try CTRL-ALT-BACKSPACE. It is usually disabled by default but worth a try.
If it isn't it should kill your Xserver.
However it is also possible that the display manager restarts everything needed, so your screen will only get blank for some seconds.

Thank you saved me a lot of work there, as FYI it was CTRL-ALT-F2 on my system for some reason.

Many thanks again·

Re: sddm login failed

Which means that in your case, the dm was occupying the first console (F1).

If you want to get rid of this in the future you could also simply avoid using a display manager and instead use startx to run an X session.
You can even add something like: 'test "`tty`" = "/dev/tty1" && startx' to your ~/.bashrc to directly start X after (CLI-)login.


Could you please mark the thread as solved? (simply prepend '[solved]' to the threads name).
