I know this can be dangerous, but it is still my preference to be able to login to a GUI as the root user.
I have managed to allow this by editing the file KDMRC, the line:
allowrootlogin=false

change it to:

allowrootlogin=true

That gets me to a GUI as root, BUT regardless of what GUI is selected, things just don't look right, and the way they do look, it's hard to find much of anything. If I use KDE as root, there aren't ANY icons at all on the desktop, and no clock!

I know you can just add all that stuff, but, is there any way to, in addition to allowing a GUI loggin as root, have the GUI appearance default to just like any other user?

NOTE - Yes I am also aware of the su terminal command - but despite the risk, I really prefer to be able to loggin in to a GUI, and have a "normal" default appearance as the root user.

If nothing else, you can do this by finding and copying all the relevant config files and such.
I suspect that they don't setup anything for root, because they don't expect anyone to use the GUI as root.

A partial answer lies in calling specific GUI apps from the command-line (as root)
