Use X desktop apps using another users on my own account, like with root
It's possible run apps from command line like root using "su root" , and later executing the app, like firefox, and works, using the data from root home. But why I can't do it with another users using "su user" ? The rest trow me one error: " No protocol specified . Cant open display" Thanks you.
Yo will have to allow the new user to access your X server.
xhost +
must be issued before su name_of_2nd_user.
