Tittel: Ubuntu: Enabling remote X-windows
Skrevet av: ATC på 02. Februar 2009, 18:44 pm

By default remote x-windows (port 6000) is disabled in Ubuntu, how do I enable this?

One easy way around this is just to use ssh to login with port forwarding like such:
$ ssh -X host
This will set the DISPLAY variable automatically and any X program you run will be automatically tunneled back through the ssh connection.

Otherwise we're going to need to enable it. Here's how:

1. Go to System->Administration->Login Window (or run gdmsetup as root)
2. Under the security tab uncheck "Deny TCP connections to Xserver"
3. Now we have to restart gdm which will kill our Xsession.
# kill -HUP `cat /var/run/gdm.pid`

or if you prefer to edit /etc/gdm.conf by hand, make sure there are no overriding settings in /etc/gdm.conf-custom. Under the security section change DisallowTCP to false.

Unfortunately we cannot use gdmflexiserver, only a gdm restart will work.
