Do you know about a good tutorial which go into what you taught?

My own script for that course is very dated (Debian 3) and in Spanish, but it is here: IntranetEducativa.pdf

I'm not aware of a similar slow paced tutorial, but may be because I no longer teach IT. Maybe projects as Linux from Scratch can be useful to you; I would give it a try, I learn a lot back in the day with it.

Long time ago I explained in a course about Debian how install X server and probing it working using the order X before installing any graphics login program. The course was very slow paced; nowadays we all can work much faster because everything works much better than 20 years ago, but knowing the basics is always useful.

Thank you Pedro for your additional input. Do you know about a good tutorial which go into what you taught?

So the problem was that SDDM did not start when necessary ATI/AMD firmware was not installed.

Did not get any error messages, but the issue was solved after installing the firmware-amd-graphics package.

I have just installed Beowulf with KDE and SDDM as display manager.

My problem is that SDDM login screen is not starting up, so as you understand I have to use the "startx /usr/bin/startkde" command to get into KDE desktop.

Could someone please advice?

Thanks,
Monti
