(1) To fix this, you need to allow other clients to access your
display. The setting of the DISPLAY environment variable only
tells the remote machine which display to use. To allow you
display to be accessed, you need to type
$ xhost + <remote machine>
Use "xhost - <remote machine>" to deny access from a remote host.
Note that this is immensly insecure!
(2) Therefore, if you have the option, use "ssh" (secure shell). This
program enscrpyts the connection and automatically forwards the X
connections (if configured to do so on the remote machine). This
way you are the only one who may access you display and you don't
have to muck with other settings.
