thank...

After investigation and discussion on irc that you can find below, the correct 
way to achieve this seems to use X-KDE-RootOnly and X-KDE-HasReadOnlyMode.
But kcm display module should also use getuid() or KUser().isSuperUser().
A forwarded bug will follow soon, when bugs.kde.org add kcmdisplay will be 
added in component list for kcontrol.

12:52 < fabo> is there a documentation about desktop entries like 
X-KDE-RootOnly and X-KDE-HasReadOnlyMode ?
12:55 < EricCartman-iBoo> fabo, I also couldn't find it atm, what exactly you 
want to know ?
12:56 < fabo> i try to make display kcm module rootonly/read only for user
12:56 < fabo> looked at lilo kcm module and find these parameters
12:56 < EricCartman-iBoo> but it's the in my dell in the service right now I'M 
afraid let me see the backups
12:57 < EricCartman-iBoo> yeah true, it's related to that parameters
12:57 < EricCartman-iBoo> where you have failed ?
12:57 < fabo> i tried it and that doesn't do expected behavior
12:57 < fabo> i've got administrator mode button, but can change options
12:57 < EricCartman-iBoo> you've mimicced a working .desktop and it didn't 
work ?
12:58 < fabo> yes
12:58 < EricCartman-iBoo> you should keep track of being root or not in the 
code iirc
12:58 < EricCartman-iBoo> with getuid etc
12:58 < EricCartman-iBoo> but kcontrol should disable the whole widget by 
defualt I guess
12:58 < EricCartman-iBoo> it's been quite a while I can't really remember
12:59 < fabo> you can easily test adding X-KDE-RootOnly=true and 
X-KDE-HasReadOnlyMode=true to display.desktop
13:01 < EricCartman-iBoo> yep you should check if the user is super user or 
not in the code

13:01 < EricCartman-iBoo> see this
13:01 < EricCartman-iBoo> ctrl+f for KUser
13:03 < fabo> user isn't super user
13:05 < fabo> i can expect that display module doesn't check correctly user 
using isSuperUser() ?
13:10 < Riddell> fabo: kcmmodules have to disable themselves is they don't 
want to run in non-super user mode
13:11 < fabo> ok, so the only one solution to achieve this is to use kiosk 
tool ? or report wishlist to display module ?
13:17 < Riddell> fabo: fix display module
