I am on Ubuntu 22.04.2, under wayland (xwayland)

I echoed DISPLAY and GNOME_SETUP_DISPLAY, but the values differs.


I would like to know why mismatches


And what about MUTTER_DISPLAY?

  • Edit your Question and show us the values of $DISPLAY and $GNOME_SETUP_DISPLAY, and explain why you think different environment variables should have the same value.

  • They're different variables, containing different values, used by different programs, for different purposes. Again, why do you think they should be the same? To see the environment variables used by a program, do strings $(type -p program) | grep -E '^[A-Z][A-Z0-9_]+$' | sort -u | more.
