I updated some software components (including X server packages) again.
Now I see undesirable software behaviour by the login procedure for another graphical desktop session.
I can move a mouse pointer around on the screen. But the login dialogue is not presented by the selected display manager (like lightdm, sddm or xdm) while the background is still black during my start attempt.
I am curious on your advices for fixing another strange software situation.
My way of avoiding these problems, is to stick to Intel graphics. I did have a box with nvidia graphics, and it was frustrating, particularly with Tumbleweed. I eventually stopped using Tumbleweed on that box. And I did not shed any tears when it finally died.
Sonne:~ # update-alternatives --display default-displaymanager
default-displaymanager - auto mode
link best version is /usr/lib/X11/displaymanagers/gdm
link currently points to /usr/lib/X11/displaymanagers/gdm
link default-displaymanager is /usr/lib/X11/displaymanagers/default-displaymanager
/usr/lib/X11/displaymanagers/console - priority 5
/usr/lib/X11/displaymanagers/gdm - priority 25
/usr/lib/X11/displaymanagers/kdm - priority 15
/usr/lib/X11/displaymanagers/lightdm - priority 15
/usr/lib/X11/displaymanagers/sddm - priority 25
/usr/lib/X11/displaymanagers/xdm - priority 10
Does that result in a working login screen?
It depends on the selection.
Yes. - The graphical login presentation is acceptable for lightdm and xdm.
No. - Only different mouse pointers are shown by gdm, kdm and sddm at the moment.
I stumble on the next software surprise. - All graphical display managers are not working in the expected way for my openSUSE desktop session at the moment.
Would you like to help any more in finding out which software components hinder the presentation of the usual graphical login interfaces here?
