一般用户工作正常,但是当我用root用户(在终端内)调用图形界面的程序时就出现下面的问题:
root@:/home/sxhong# gedit
Xlib: connection to ":0.0" refused by server
Xlib: No protocol specified
(gedit:2650): Gtk-WARNING **: cannot open display:
root@:/home/sxhong# xmms
Xlib: connection to ":0.0" refused by server
Xlib: No protocol specified
** CRITICAL **: Unable to open display
