Hi Christian, databunka ~ # echo $DISPLAY localhost:10.0 Thats shown when i do echo $DISPLAY on the machine. when i connect from a remote system with ' ssh -Y root@....' the virt-manager pop up like it should. the problem was only when i sit infront of the machine, logged in as user 'root'. my thought was that something is wrong with gtk or so , because of the error message.

...

 File "/usr/share/virt-manager/virt-manager.py", line 285, in main    raise RuntimeError(_("Unable to initialize GTK: %s") % gtk_error) RuntimeError: Kann GTK nicht initialisieren: could not open display

maybe its the X11DisplayOffset 10 in the sshd.config ? marko Am 18.01.2012 10:15, schrieb Christian Parpart:

i already remerged gtk

Hi Marko,

make sure you have the DISPLAY variable exported to root as I asume you've been logged in as user but then dropped privileges up to root and maybe your user environment wasn't inherited from within your X session.

# echo $DISPLAY :0

So long, Christian Parpart.
