hi all, just upgraded to new kali and have found that VNC is no longer working - was working perfectly fine on 1.x

using the same command:
#vncserver -geometry 1024x768

it starts the server and from my computer i attempt to vnc to the box.

the connection starts but get the grey screen with a sad computer face saying

"Oh no! Something has gone wrong.

a problem has occurred and the system can't recover
please logout and try again"

it has a big logout buttton with the big black X.

any help would be appreciated
