Hi Gene
You missed the point, it demands a root pw, that on this wheezy system, does not exist, so it cannot be launched from the menu entry by any pw entered. The pw used for doing a sudo is not accepted. That was my point.
Don't put it in the menu's at all if the user cannot use his sudo to get the root rights it needs.
what happens, if you do - if you are allowed to start su from sudo:
xhost + # to allow other users to access the xserver sudo su # to become root without a password export DISPLAY=:0 # set the DISPLAY variable to access the xserver ksysv # start the wanted program
If this works, you can use the program without a password.
