This is a simple question which should be obvious but I’ve Googled and I don’t see an answer.
If I set up X windows remotely like this: https://fabianlee.org/2018/10/14/ubuntu-x11-forwarding-to-view-gui-applications-running-on-server-hosts/
Can I share one Ubuntu box with another where both of us are running X windows, so both of us are hitting the graphics card?
NOTE: There is a similar question from 2010. Has anything changed or are the replies there the state of the art?
