It seems my display server (X11) has gone bad. This isn't the first time that it's happened so I'm not too suprised, but I'm tired of reinstalling this OS. After two months the X11 server craps out and it refuses to open any GUI applications. What's weird is that the applications will run when the computer isnt connected to the network. When the box is connected to the internet all new GUI applications that are attempted fail. Also, when running a GUI application from the command prompt (ex. gedit) I get this error.

[root@localhost ~]# gedit /home/lorenzo/macSpoof.txt
Xlib: connection to ":0.0" refused by server
Xlib: No protocol specified


(gedit:3272): Gtk-WARNING **: cannot open display:

Help. Anyone?

Does X work fine as a normal user. If you are switching to root from a normal user account and need to run gui apps, then do
To save you the hassle why not use a text based editor e.g. pico (nano), vim or emacs.

No it gives the same message when I try to run a GUI or a GUI from command line as a normal user. The weird thing about it is that it only happens after I've spoofed the MAC address. If I leave the MAC address on my network card alone I'm fine.
Additionally, I do use vim from time to time but that was a test to see if there was something wrong with my display server. Iwas searching for an answer to save an OS, not a replacement for a text editor. Thanks anyway.
