Re: switch users and still use display

[Hans <hans.ullrich@loop.de>]

Some window managers are offering an option, to change the user (plasma = KDE 
does it, for example.). It is also possible, to start a new X-session and 
login with another user. Doing so, you have 2 X-session open.

The option is also, to change the user, or, add another user with a new 
session.

Sometimes, I need to start an application as root in X (for example, if I want 
to edit a configuration file, only rott is allowed to edit) ands I want to use 
a graphical writer, like kwrite (just an example). 

Instead of logging out and relogon into the window manager as root, I am 
starting a shell., and enter "su -p" (this meany, preserve my environment). 
Thus I can start any graphical application from the shell (starting kwrite 
with the command) and it will start with root permissions.

In earlier times, there was "sux" a wrapper for su, but this is no more 
available.

I never found an official documentation about "su -p", just found it myself, 
but I read, "su -" shall do the same. It does not.

Maybe your question aimed to this scenario, if so, there is my solution.

Have fun!

Best
