Quota conditions
vncserver may not start if you are over your AFS quota.
Authentication
Likewise, vncserver may not start if you do not have a valid Kerberos ticket and AFS tokens. Try re-authenticating before starting VNC.
kinit && aklog
Resetting the shell configuration
Some kinds of changes to ~/.cshrc and ~/.login (or other shell configuration files) may break VNC; in particular, setting up the environment for certain applications (e.g., Cadence) according to instructions is known to cause problems. You can restore the default shell configuration by running updaterc.
/usr/pubsw/bin/updaterc
Resetting VNC state and configuration
A common troubleshooting method is to reset the VNC configuration by deleting the ~/.vnc application directory.
rm -rf ~/.vnc mkdir ~/.vnc vncpasswd
