Make sure you are using the 3.5 NX Client and all of the fonts.
If you do not have the installer or can't find it bring a flash drive to csg and we can give you a copy.
Also make sure you have GNOME set as your desktop not KDE.
If you have problems connecting using NX or think you may have a hung NX session.
Try this, log in with putty or other ssh client then run the following commands
# killall nxnode # killall nxagent # rm -rf ~/.nx/C*
# ps -u <username>
and kill any NX process that is still running using
# kill -9 <pid>
If you see
*ERROR* Failed to find either 24-bit TrueColor or 8-bit PseudoColor Visual. *WARNING* Failed to find either 24-bit TrueColor or 8-pbit PseudoColor Visual.
