Problem

On Ubuntu remote display in X doesn not work.

Analysis

We need to remove “-nolisten tcp” from X command line.

Solution

  1. This is sometimes in “/etc/X11/xinit/xserverrc”, but in Ubuntu you just need to configure GDM:Create or edit file /etc/gdm/custom.conf with the following content:
    [security]
    DisallowTCP=false
  2. Restart X or reboot.
  3. On the remote machine
    $ export DISPLAY=yourcomputer:0.0
  4. On local machine
    $ xhost + remotemachine
