[FreeNX-kNX] “Could not find shadowed session” error

[Yang Zhang]

I just installed FreeNX on my Ubuntu box:

add-apt-repository ppa:freenx-team/ppa
aptitude update
aptitude install freenx

Using the NoMachine nxclient, I'm selecting Shadow Session and I can
authenticate, then I see two sessions. Whichever one I choose, I get
the below error. Any hints? Googling has not been fruitful. Thanks in
advance for any help.
