User can't start firefox
I just installed debian on a computer for a friend (PIII 500meg ram)
and everything has gone fairly well. I installed firefox and thunderbird
and some of the basic programs.
Root can start and run firefox and thunderbird. there is only 1 other
user. He can start thunderbird but not firefox. When entering the command
mozilla-firefox from the terminal there is a error message.
Xlib: connection to ":0.0" refused by server
Xlib: XDM authorization key matches an existing client!
(firefox-bin:1449): Gtk-WARNING **: cannot open display:
How do I correct this situation with the authorization keys? I do not
understand what it is referring to, or how to correct it.
Any suggestions appreciated.
