[X2Go-User] x2go overwrites LD_LIBRARY_PATH

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.

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=1038834

My fix of choice is to change the first line of /usr/bin/x2goruncommand to:

     #!/bin/bash -l

That'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
