I've only been using mepis linux for about a year now, and I've self taught myself on alot of things, but I don't get this problem...

Whenever I want to run as root, I can in the console. (su, then password). But when I open file manager su mode or mepis config (os center) in GUI mode it wont accept my password.

so I tried changing the password in the console and this is what I got:


root@2[thehuntedcat]# kdesu
Xlib: connection to ":0.0" refused by server
Xlib: No protocol specified

kdesu: cannot connect to X server :0.0

root@2[thehuntedcat]# xhost +
Xlib: connection to ":0.0" refused by server
Xlib: No protocol specified

xhost: unable to open display ":0.0"
root@2[thehuntedcat]# synaptic
Xlib: connection to ":0.0" refused by server
Xlib: No protocol specified


(synaptic:7936): Gtk-WARNING **: cannot open display:
root@2[thehuntedcat]# konqueror
Xlib: connection to ":0.0" refused by server
Xlib: No protocol specified

konqueror: cannot connect to X server :0.0
I have no idea what to do.

I went and looked at more forums, and people have been telling me to use xauth, so I typed that in, then when I went to list it doesnt work.


root@2[thehuntedcat]# xauth
xauth: creating new authority file /root/.Xauthority
Using authority file /root/.Xauthority
xauth> list
xauth> list
Anybody got any ideas?
