Feisty: gksu/gksudo don't work on thin clients?

[Philipp Hanselmann]

Hi

I tested this again, its only happen with LDM_DIRECT = True, otherwise 
gksudo/gksu is working on the thin clients.

May this is in connection with the DISPLAY variable during a client 
login, which is different with deactivated encryption (LDM_DIRECT = True).

with LDM_DIRECT=true
echo $DISPLAY         192.168.0.249:6.0

otherwise (without this option)
echo $DISPLAY         localhost:11:0


Can somebody help ?
