Tag: X server remote connection port 6000

Howdy folks, i needed to start my X.server on Ubuntu LTS Gnome, which should be able to listen for remote connection on port 6000, the gdm has been configured.

Modified /etc/X11/xinit/xserverrc as

#!/bin/sh
exec /usr/bin/X "$@"

Set DisallowTCP=false in /etc/gdm/custom.conf

[security]
DisallowTCP = false
[xdmcp]
[greeter]
[chooser]
[debug]

Restarted gdm

sudo service gdm restart

Check wether gdm listening on 6000

sudo netstat -tlnp | grep 6000

but result is empty

sudo ps lf -C Xorg command gives

F   UID   PID  PPID PRI  NI    VSZ   RSS WCHAN  STAT TTY        TIME COMMAND
4     0  1362  1342  20   0 176672 61764 poll_s Ss+  tty7       0:02 /usr/bin/X :0 -background none -noreset -verbose -auth /var/run/gdm/auth-for-gdm-XkGfsT/database -seat seat0 -nolisten tcp vt7

Solution:

After modifying /etc/gdm3/custom.conf content by adding ServerArguments=-listen tcp. I got xserver running on port 6000

[security]
DisallowTCP=false
[xdmcp]
ServerArguments=-listen tcp

Note:

I get this too. I made a similar change in /usr/share/gdm/gdm.schemas as well, rebooted, and no X11 server listening on port 6000 🙁 I even see this: shell /usr/lib/gdm3/gdm-x-session --run-script --allow-remote-connections env GNOME_SHELL_SESSION_MODE=pop gnome-session --session=pop Note the use of –allow-remote-connections
