Research direction
Start by reproducing the reported enroot start -r Test and xeyes sequence with the Ubuntu container, then compare it with enroot start Test and the working host terminal. Investigate the reported X11 authorization and localhost:50.0 display error; the issue is resolved when GUI applications launch successfully inside the container.

Description
Hi Team,
I cannot launch any GUI (Graphical User Interface) application from the Enroot container. But I can launch any GUI application outside Enroot container (i.e., regular Terminal of HPC cluster), and it works fine.
I am using an Ubuntu container (ubuntu.sqsh) and installing GUI packages like xeyes, xterm, etc., from the root(apt-get install x11-apps).
The commands are available to use, but whenever I try to launch xeyes, it shows:
MoTTY X11 proxy: Unsupported authorisation protocol
Error: Can't open display: localhost:50.0
Can you guys please help me to resolve the above issue?
Steps that I have followed:
-
enroot create -n Test ubuntu.sqsh
-
enroot start -r Test
apt-get update && apt-get upgrade
apt-get install x11-apps
- enroot start Test
$ xeyes
MoTTY X11 proxy: Unsupported authorisation protocol
Error: Can't open display: localhost:50.0
