Are there some dependencies that need to be installed? I am on Ubuntu 20.04 and have x11, not Wayland.

I also noticed when I click open virtscreen after clicking the system tray icon in the top right, the GUI appears for a brief moment, then disappears.

I tried following your blog here https://kbumsik.io/using-ipad-as-a-2nd-monitor-on-linux.html but get different errors from the command line:

Try installing python-quamash and python-netifaces. Note that installing via. pip won't work - you have to install them using your package manager

@CAG2Mark that is good to know but this still does not fix the issue. I have the same problem as them and it still has that error message.

I don't know then. Either way, I couldn't get the actual functionality working even with the dependencies working.
