Troubleshooting VNC

Instructions for running Cadence may recommend sourcing the script that sets up its environment, DOT.cshrc, in ~/.cshrc. This script makes changes to $LD_LIBRARY_PATH that can break other applications, including vncserver If you find that you are unable to start a new VNC session after following such instructions you can restore the default shell environment by running updaterc. /usr/pubsw/bin/updaterc The DOT.cshrc file can then be sourced manually after connecting successfully. Alternatively, you can set $LD_LIBRARY_PATH in ~/.cshrc before sourcing the file, to ensure that VNC can find its libraries. setenv LD_LIBRARY_PATH /lib/x86_64-linux-gnu:/usr/lib/x86_64-linux-gnu source /usr/class/ee315a/DOT.cshrc Setting or changing this environment variable in ~/.cshrc or ~/.login is NOT recommended, however. If sourcing DOT.cshrc manually is inconvenient, a better solution would be to create a local wrapper script for Cadence that sets up the environment before starting the application.
