I need to run a gui-based application on a remote PC to which I am connected over telnet. The remote PC runs Linux Ubuntu 18.04

To figure out the screen, I run the following command on the remote machine:

echo $DISPLAY

which gave me :1 as result.

Then I run the program on the remote machine from my client (over telnet) using:

DISPLAY=:1 application_name

The program started correctly (since, in addition to the GUI, it prints some things on the command line) but the GUI didn't show up. But, if I run my app directly on the remote machine, everything is fine.

As a test, I tried to run firefox browser on an another machine (always through telnet) with the following command:

DISPLAY=:0 firefox

and it worked. Note: on the other machine the output of echo $DISPLAY was :0. Furthermore, I could not test my app on the second machine.

It seems that there are different settings between the two machines since what I'm trying to do works on a machine, but not on the other.

Do you have any idea of what type of setting should I check?

Did you try to run your application on the first remote machine but with DISPLAY=:0 instead of :1?

What is the error message you get from application when you started application in the first case ("DISPLAY=:1 app_name").
