I found a (lengthy) guide to doing this but it is for gksu which is gone. I have to imagine there's an easy way. I am running Ubuntu. There is no specific use case, it is just a feature I miss from windows.
EDIT: I always expect a degree of hostility and talking-down from the desktop Linux community, but the number of people in this thread telling me I am using my own computer that I bought with my own money in a way they don't prefer while ignoring my question is just absurd and frankly should be deeply embarrassing for all of us. I have strongly defended the desktop Linux community for decades, but this experience has left a sour taste in my mouth.
Thank you to the few of you who tried to assist without judgement or assumptions.
I think you can run like this:
$ pkexec env DISPLAY=$DISPLAY XAUTHORITY=$XAUTHORITY <yourapp>
For example, if I wanna open
kgx
(a.k.a. Gnome Console), I would run:pkexec env DISPLAY=$DISPLAY XAUTHORITY=$XAUTHORITY kgx
Don't do this. I'm unsure if this works in any distro, but if it does, this is unsecure.
