so Thunar appears with red warning label. But when I want open file (for example text file in mousepad) from that window, nothing happens.
I'm on Ubuntu 9.10 KK. In some earlier version (I don't remember how long ago) in described above situation I could open text file in musepad with admin privileges.
Is it bug or some security feature?
Before you run gksu, run these following commands. Then try to use mousepad etc.
Thank you! It works
Now I have add to my Thunar actions:
export DISPLAY=":0.0" && gksu exo-open %F
