cannot conect to Gnome/KDE via nxclient

Thank you for taking the time to report this bug and trying to help make Ubuntu better. However, it seems that you are not using a software package provided by the official Ubuntu repositories. Because of this the Ubuntu project can not support or fix your particular bug. Please report this bug to the provider of the software package. Thanks!

If you are interested in learning more about software repositories and Ubuntu the following pages should be informative:

1. [WWW] http://www.ubuntu.com/community/ubuntustory/components - information about Ubuntu repositories
2. [WWW] https://help.ubuntu.com/community/Repositories - information regarding managing repositories

I got the same for KDE. BTW. GNOME does show up for me, in full screen mode.

I have the same problem. Even with the packages from the repo: freenx and qtnx. In that case, the log doesn't show any helpful message like in the official package's log. The interesting thing is, that with another user, I can login.

From offocial package's log:
success with other login:

fail with my login

(dbus-x11 installed)

I found the solution to my problem:

I played with libtrash and other trash things, and had this in my .bashrc and .bash_profile. When I removed these, nx started working.

# Include this in your ~/.bash_profile to enable libtrash every time you
# log in (or otherwise start a login shell)
#LIBTRASH=/usr/lib/libtrash/libtrash.so
LIBTRASH=/usr/lib/libtrash/libtrash.so.3.2

LIBTRASH_dest=$LIBTRASH
if test -L $LIBTRASH ; then
   LIBTRASH_dest="$(dirname $LIBTRASH)/$(ls -l "$LIBTRASH" | \
                                         sed -e 's/^.\+ -> //')"
fi

if test x${LD_PRELOAD+set} = x -a -f "$LIBTRASH_dest" ; then
   LD_PRELOAD="$LIBTRASH"
   export LD_PRELOAD
   if test x$0 = x-bash ; then
      exec bash ${1+"$@"}
   else
      exec $0 ${1+"$@"}
   fi
fi

Closing due to previous comment: it was a user configuration issue.
