I have tried extracting and merging the magic cookie of the Thin client's xserver into the xauth of the unix machine exporting the display. The error message still doesn't change.
I don't think its an authentication problem from what I have read since I'm still getting 'Cant open display'. If it were an authentication problem I would expect to get errors along the lines of
Xlib: connection to "glenlivet.mfcf.uwaterloo.ca:0.0" refused by server
Xlib: Client is not authorized to connect to Server
X11 Toolkit Error : Can't open display: glenlivet.mfcf.uwaterloo.ca:0.0
I got this info from http://www.math.uwaterloo.ca/mfcf/fa...rm_display.faq
Im still battling on; any ideas would be greatly appreciated!
