There is a way to add users to a given display and remove users from a given display, but not to just swap. You could do this by having each user run xauth to add the other user to their display, and then using xauth to remove themselves from the original screen. That seems like a lot of work, since it involves copying authorization data from one account ...

Ok, so it appears this was an issue with the Gnome Dropdown Terminal extension. Under settings > Terminal, I had a custom command setup as "tmux". Removing this solved the issue.

(Ok, technically it's possible by running a debugger on the X server process and issuing the right commands. The wrong commands will crash the X server if you're lucky. This is not likely to succeed.) Whatever problem you're trying ...

There is a component called Polkit that is used by many applications to request root permissions to do things (it can do so because it's a daemon running as root). Polkit can be configured to ask for a password (either your user account password or the root password) or to just allow it without a password prompt. That decision can be based on any number of ...
