At least one S10 system fails to launch X2Go

I have been testing our solution on the S10 platforms, part of which requires a web browser to view our demo UI. X2Go is the simplest solution for this currently (we'll look at tunneling later).

s005-n008 was the system assigned by devcloud_login. I was able to get around this by logging out of that system, running 'pbsnodes -s v-qsvr-fpga' to find a free S10 and ' qsub -q batch@v-qsvr-fpga -I -l nodes=s005-n009:ppn=2' to get a different available system.

I've also noticed differences in the system configurations (mostly minor, dealing with /opt installations). These systems should be cloned and up-to-date (wish they were Ubuntu as well - sigh).

    Steps to reproduce:

    1. ssh devcloud
    2. pbsnodes -s v-qsvr-fpga|fgrep -A1 s005-n008 # verify system is free before next steps
    3. qsub -q batch@v-qsvr-fpga -I -l nodes=s005-n008:ppn=2 # to get an interactive shell
    4. (In a new terminal on your desktop)
    5. ssh -L 4002:s005-n008:22 devcloud # this establishes the X2Go tunnel
    6. Launch X2Go client per instructions.
    7. Observe that xfce4-session fails to launch.

    The above steps work on other systems I have tested so far.

      Hi @GrueMaster,

      Thank you for posting in Intel community forum and hope this message find you well.
      We are still trying to investigate further on this, but as a high level analysis I am suspecting that it might be a missed in some configuration.
      Please do refer to the following suggest in the link here to see if that works.

      Warm regards.

        So, given the fact that it works on multiple other systems EXCEPT s005-n008, you thing it is something wrong with my local x2go setup? Really?
