Hi everyone,

I just received my new Slimbook Evo 15 with Kubuntu installed. I started it and had a few windows from the welcome center. As I did not undestand everyting (I am new to Linux, transitionning from macOs) I went for a while on an other computer to look things up. When I came back to the Evo, I was asked for my password, which I had not set yet. I had forgotten what was written in the manual about the username and password being slimbook, and clicked on "other users" out of curiosity. I got a black screen with a flickering cursor _ , and I don't know how to recover from this.

I found this link : https://slimbook.com/en/blog/guides-2/post/black-screen-with-cursor-after-upgrading-kde-neon-plasma-6-444#  and tried the suggested shortcuts, but none worked. I guess that just rebooting would solve the problem since I did not change anything in the settings, but I could not find how to do that. Any idea ? Thanks !
