Swithing between gdm and kdm

[Rene Harder Olsen]

Hello everybody.


I have read the mails about enabling lightdm and disabling gdm.
I have also tried it and what I found out was, it sets display manager
via and ln which it modifies by creating a new one for the one which is
enabled and removed the one which is disabled.

Dnf says that kde and gdm is installed and when I changed it has no
effect on graphic desktop displayed.

Any tips or help is more than welcome.

Can it has anything to do with the sudoers file I have set to no login
at boot.

i am not native English speaking person so please bear with me.
