Graphics not working in Ubuntu 20

[jrmchal]

When using the latest rat-container in Ubuntu 20 using the command docker run -ti --rm --user $(id -u) -e DISPLAY=$DISPLAY -v /tmp/.X11-unix:/tmp/.X11-unix -v /home/jonathan/sno+/rat/:/rat jamierajewski/rat-container, the graphical output (such as TBrowser in ROOT) does not work. The error message is:

Error in <TGClient::TGClient>: can't open display ":0", switching to batch mode...
 In case you run from a remote ssh session, reconnect with ssh -Y

However, using the remote shifting container with the command docker run -ti --net=host --rm --user $(id -u) -e DISPLAY=$DISPLAY -v /tmp/.X11-unix:/tmp/.X11-unix registry.gitlab.com/jamierajewski/remote-shift-container/release graphical output works with no problems.
