> I think : would be a correct designation for a wayland session within last

I can understand probably thats the right thing to do because of the way
wayland works. You may close the bug as invalid.

I want to know couple of things and I am sorry to use the bug to find the
information. I did lot of googling and digging, but could not find proper
answers.

1. How do I programmatically find the display number on which a desktop user is
logged in so that can export the display of a graphical application to the
desktop ? None of the commands like last, who, loginctl seems to help.

2. Whether "export DISPLAY=..." is the right way with wayland or there is any
better and recommended way to export display ?
