Once set up, VNC seems to be very reliable. There are one or two problems which can arise however.
then check that the VNC server is running by doing something likevncviewer: unable to connect to VNC server
If no Xvnc process is running, then either you haven't run vncserver or it ran into problems. If vncserver was run, then check% ps aux | grep vnc mbt 1349 6.7 6.6 5236 4200 p2 S 17:53 0:00 Xvnc :1 -desktop X -h mbt 1414 0.0 0.5 852 348 p2 S 17:53 0:00 grep vnc

/.vnc/X.log" for errors.
If there is an error like
Failed to establish all listening sockets
then check the permissions on the directory /tmp/.X11-unix;
it should have world write access.
If an Xvnc process is running, then check that you have
used the right display number (:1 in the above example).
If Xvnc processes are left running, they will not allow X display numbers to be reused (e.g. if Xvnc :1 is still running when vncserver is run again, the next display will be :2), and will consume some system resources.% ps aux | grep vnc mbt 1349 6.7 6.6 5236 4200 p2 S 17:53 0:00 Xvnc :1 -desktop X -h mbt 1414 0.0 0.5 852 348 p2 S 17:53 0:00 grep vnc % kill 1349
