Known issues
When using additional commands in ~/.bashrc or ~/.bash_profile, X2Go mistakes the output from certain commands as error messages and will crash or hang when starting a new connection.
module load
When using "module load" to load modules in ~/.bashrc or ~/.bash_profile, the output from "module load" can be misinterpreted as an error.
Solution:
For example with fsl module, edit your "module load" command in your .bashrc or .bash_profile as following
module load fsl > /dev/null 2>&1
This will redirect the output from "module load" to /dev/null
fix_perms.sh
When using fix_perms.sh or other commands to resolve permission issues when starting new shells, X2Go can freeze due to any "permission denied" messages that occur.
Solution:
- Place fix_perms.sh or any other commands in ~/.bash_logout
Commands in ~/.bash_logout are issued when a bash login shell exits. This should resolve issues with X2Go and also allow users to continue using these commands.
