I have had many problems to change my KDM in kde4.4.0 because of permission troubles to acces on systemsettings like root user.
When we want change our KDM is necessary root or superuser permissions, but when we execute systemsettings we enter on it without root. Foir this reason i didn't can change my KDM. I think it is a bug in KDE.
I've tried from terminal with: su, gksu and kdesu commands but not work fine.
The solution is:
Press the keys ALT+F2, then write
Code: Select all
kdesu systemsettings
and change your own preferences
bye,
Tobal
