Cross posted to superuser as this may be relevant there http://superuser.com/questions/389992/freenx-stopped-working-after-upgrade-to-ubuntu-11-10.
I installed Ubuntu 11.04, installed FreeNX server and FreeNX client for Windows from http://www.nomachine.com/download-client-windows.php. I was able to connect to my ubuntu from my windows laptop.
With the recent upgrade of Ubuntu 11.10 whenever I try to launch my FreeNX from my laptop, it accepts the password, initialises the session and just when it is about to display the window the window suddenly closes and says "the connection with remote server was shut down"
This is driving me mad. Can someone please tell me why?
