Hi,
I am using x2go to connect to machines running Ubuntu 14.04.3 LTS. I had trouble running commands that rely on finding libraries via the environment variable LD_LIBRARY_PATH. LD_LIBRARY_PATH is set in a script in /etc/profile.d because this is a system wide configuration and it needs to be performed once per login. Using ssh to remote login, LD_LIBRARY_PATH is correct:
echo $LD_LIBRARY_PATH /usr/lib/fsl/5.0
When I login using x2go, LD_LIBRARY_PATH seems to be reset and contains only the entries regarding x2go:
echo $LD_LIBRARY_PATH /usr/lib/nx/X11/Xinerama:/usr/lib/nx/X11
My guess is that there is probably an error in /usr/bin/x2goruncommand, along these lines:
test -n "$LD_LIBRARY_PATH" &&
LD_LIBRARY_PATH="$NX_XINERAMA_LIBS:$NX_LIBS:$LD_LIBRARY_PATH" ||
LD_LIBRARY_PATH="$NX_XINERAMA_LIBS:$NX_LIBS"
"$X2GO_LIB_PATH/x2gosyslog" "$0" "debug" "exporting
LD_LIBRARY_PATH=$LD_LIBRARY_PATH"
export LD_LIBRARY_PATH
But I can not see why it is that my path only contains $NX_XINERAMA_LIBS:$NX_LIBS, and not $NX_XINERAMA_LIBS:$NX_LIBS:$LD_LIBRARY_PATH.
Thank you for your help!
Best Thomas

Hi Thomas,
You posted a month ago, so I hope you've already found a fix. I'm responding anyway, if anything for future-me, as I just encountered this problem, troubleshot it, and then realized that I ran into the same thing a few years ago the last time I installed x2go.
My guess is that there is probably an error in /usr/bin/x2goruncommand, along these lines:
test -n "$LD_LIBRARY_PATH" &&
LD_LIBRARY_PATH="$NX_XINERAMA_LIBS:$NX_LIBS:$LD_LIBRARY_PATH" ||
LD_LIBRARY_PATH="$NX_XINERAMA_LIBS:$NX_LIBS" "$X2GO_LIB_PATH/x2gosyslog" "$0" "debug" "exporting LD_LIBRARY_PATH=$LD_LIBRARY_PATH" export LD_LIBRARY_PATH
The lines that you excerpted from x2goruncommand are correct. The problem is that your profile(s) isn't being run because bash isn't being invoked as a login shell. There are a number of fixes for this; see:
https://bugzilla.redhat.com/show_bug.cgi?id=1038834My fix of choice is to change the first line of /usr/bin/x2goruncommand to:
#!/bin/bash -lThat's it! Just add a space and two characters! This probably violates all sorts of shell and X propriety, but I pretty much always use x2go to run full desktop sessions, so this has the desired effect for me.
Best regards, H

Once nxagent 3.6.x is used with X2Go, the overwriting of
LD_LIBRARY_PATH becomes obsolete.
