I think it is only things stored in user2's /home that the mail program would need to access, and HOME is set without needing a login shell. I guess that is why 'su user2' works for me since I have no substantially different environments on my system, where "user2" is essentially a guest account. It is also not uncommon for me to already be logged in as root when I am playing with other user accounts. > > | >>> mail_program_name & > | then close the program and type "exit" in terminal to close > | > | I believe that should work, though I have not tried the specific example I > | am describing. > > If the mail program is a text based one, no worries (except for > certain niche situations).

However, the following at terminal: >>> su user2 >>> sudo firefox will open open firefox in the existing X session of "user1" while sourcing user2's firfeox profile/bookmarks, etc. I assume a graphical mail environment would behave the same. I did forget the command to open the program needs to be run as root, which has the usual security/safety issues. There is a way also to assume the active .Xauthority file from a different login shell for a priveledged user (or something like that). And that is probably the way it should be done. I'd have to do heavy google to have a better clue of what I am talking about here, as it has clearly been longer than I can remember. Wiki.x.org would probably be a good place to start if I was going to try and do it right. > I've been using a Mac as my desktop for too long; can modern Linux > systems run multiple "live" X11 desktops (live MacOSX "user > switching")? > At least since Ubuntu 10.04, there has been a "switch user" from the login/out options. It suspends the session of the active user, and lets a different user log into their own desktop environment, I think in a different tty. This can be accomplished manually I am sure, but I don't know how. It should not be too complicated though. I can't speak for other distributions, as I have only experience with Ubuntu and Debian. I am not sure if the current Ubuntu is still using X, now that I am thinking about it...
