My situation is I am logged in to gnome with a user, and through the terminal I am trying to run steam as a different user with the error
unable to open a connection to X. Both users can run steam fine from their own gnome shell login, so I assume this is some conflict with x already being used by a different user. Any way to allow this?
Also as a side question, opinions on whether there is any point security wise to running steam through its own user? My thoughts are that there will be many games running through it that I don't want to give access to my personal files in my main users home directory.
