X does not start automatically

Hi there,

Tumbleweed 20211102 here.
Something happen to my machine. X does not start automatically anymore.

However if I logon as root on console and ran “startx”, the X start with the root KDE DE, as expected. Resolution looks like ok, fonts are normal, all as expected.
Of course, I can not login directly as normal user as startx is not setuid…
Also, If I add “nomodeset” to grub command line, then X is started as usual, showing the display manager to the user logon.
I never had to use nomodeset before. It is not present on grub command line by default.
What happened here ?
The use of nomodeset is mandatory now ? I missed something in the last releases ?

I should add that my computer was off in the last few weeks. I am painting my house and the computer was off all that time. Yesterday I updated tumbleweed from 20211029 to 20211102, and that happened. Some explanation, please ?
