Package: NXAGENT Version: 3.5.0
I would like to bypass setting of certain environment variables in .bash_profile if I’m connecting via x2go, but it appears there are no environment variables I can test in .bash_profile to determine if this is an x2go session. After the session starts, some x2go environment variables are there, but not while .bash_profile is executing.
Ted,
I have made my software switchable between GUI non-GUI by examining the DISPLAY variable - if it is NULL then x2go is not being used.

Unless, of course, you are occasionally using a local X session, or regular X forwarding, where this approach will bite you in the posterior, falsely assuming that you're running an X2Go session when it's regular X.
The deeper-rooted issue here is that X2Go-specific variables are only set when a session is run in fullscreen or windowed mode, displaying an entire desktop.
For single/published applications, no such X2Go-specific variable is set.
However, you can check if:
the command x2golistsessions is executable (=we're on an X2GoServer - important in case of NFS-mounted home directories)
AND the DISPLAY variable is set
AND client DISPLAY and SSH client IP match an X2Go session marked as "R" for running.
See <http://wiki.x2go.org/doku.php/doc:howto:ssh-agent-workaround>, section "# Part that runs in X2Go session", for an example where you could lift the required code.
What you don't need is the part that checks for a file named "~/.x2go/agent", so just remove that part.
Kind Regards, Stefan

I’m running in windowed mode (XFCE) through x2go and XQuartz. The DISPLAY environment variable is not set.

DISPLAY is null (not defined) when x2go is running, as well as when it isn't, in my case. — Ted Toal, Postdoctoral Researcher Carvajal-Carmona Lab 4502 GBSF, One Shields Ave Davis, CA 956626 (530) 263-5986 twtoal@ucdavis.edu
Sorry – I am using headless servers that never have X running on them – That solution is limited.
