I'm trying to run several compute intensive python scripts on a server (Ubuntu 14.04.5 LTS) via ssh -Y and tmux. This works fine as long as I don't close the ssh connection. If I do close the connection, the currently running script will finish properly but the all scripts starting afterwards will get the error

gtk-WARNING **: cannot open display: localhost:10.0

The scripts are command-line-only but perhaps a library used for some reason needs a display. If I disconnect, the display is gone (my assumption). Is there a way to fix this (preferably without root access), perhaps a way to fool ubuntu into thinking there's a display while there is none?

EDIT:

• I first connect to a vpn and then ssh into the server (with -Y flag)


• I'm trying to run this script in a loop with different parameters each time. It uses matplotlib.use('Agg') so matplotlib shouldn't be the problem (?) I can't think of anything else.


• 
  echo $DISPLAY returns localhost:10.0 before the error. If I connect from a different computer it returns localhost:13.0. If I left the terminal on the original computer open, it will still return localhost:10.0 however if I open a new one it will now also return localhost:13.0
  


• X11-Forwarding works normally, I can run any desktop app I tried so far. The problem are scripts that start after I disconnect/logout.

  @SavvasRadevic Thank You for trying to help me! echo $DISPLAY returns localhost:10.0 before the error. If I connect from a different computer it returns localhost:13.0. If I left the terminal on the original computer open, it will still return localhost:10.0 however if I open a new one it will now also return localhost:13.0. Could intermittently connecting from a different computer be the problem? However the script seems to have already failed before I connect again (not sure though)

Try setting the DISPLAY variable:

export DISPLAY=localhost:10.0

And then execute your commands.

  This does not work. As I said, X11-Forwarding works fine, what I need is a way to schedule scripts that require x-server without the need to be constantly connected. Scripts which start after I close the connection fail because the display at localhost:10.0 is no longer accessible. Something like this should work, unfortunately I don't have the rights to install packages and can't test it.
