[Linux] x errors

[Larry Kagan]

In the interest of security, I performed the following command:

$ chmod o-rwx /home/*

Now I get the following errors in ~/.xsession-errors when trying to 
start any graphical application:

Xlib: connection to ":0.0" refused by server
Xlib: No protocol specified


(gnome-terminal:7234): Gtk-WARNING **: cannot open display: 


No errors reported in /var/log/messages or /var/log/syslog.


In an attempt to debug, I chmod 777 .Xauthority .ICEauthority but with 
no luck.

Any ideas?

Thanks,

Larry
