So I found no solution to bring the login window on start up back, I decided to play the rescue-install show.
I am curious how this will end.

If not any promise will come true, for one thing is (Suse SLED) Linux is superb, there is always a surprise.

Here and there noone has any duty to bring it. Clear.

But it is from the land of fairy tales, that linux is better.
For a private enduser it is best to use a MS windows OS.
Linux is too time consuming, unconvinient and (as you see with the faulty login window) not that stable.

If you want to install a programm and installing method one, two and three not functioning. Finally you try it manually, only for finding out that you need library xy, which indeed needs kakuki, which needs also something. Than instead of a running programm, you have a lot of wasted space on your hard disc.

As clear as you think, noone is responsible for that. We are all grown up.
And if you have some 10 years of experience, congratulations, than linux is better.

For the normal user, MS Windows beats linux in all aspects.
Maybe it is more secure. But for that you have to use 2 external hard discs. And if you do not make a lot of system changes, than also MS windows is stable enought. I had no crash for the last years.
