If you want to use a desktop environment on a Linux cluster, it is strongly adviced to use the Ponyland VNC, as (1) the system running there is considerably easier to use, (2) the system running there is fully optimized for our group, and (3) it is more efficient for Wessel Stoop to only have to support one system. If this is not possible, this is what you have to do to get VNC running on Smurfland:
cdto your home directory.
cd ./vnc. If you get a
permission denied, please contact Wessel Stoop, as this folder and all files in it will need to be accessible from your account.
lsto view the contents of this folder. There will be two files ending with a number. This is your display number. If these two files do not exist yet, run
./vnc_startto create them.
vnc_start, and replace
DISPLAY=:ddwith your display number.
./vnc_start. If this reports any problems, fix these problems and try again.
ddis your displaynumber.
passwdin the same directory as
.vnc_start, and restarting the server software.
