First you need uncomment this lines in /etc/ssh/ssh_config on server:
1 | X11Forwarding yes |
The second step is connect to server with -X and execute Chromium
1 | ssh -X user@hostname chromium |
You will see it on client computer.
BTW, you don’t want to use the -Y flag instead of the -X flag?
Quite simply, the difference between -X and -Y is that -Y enables trusted X11 forwarding.
