This is on Ubuntu 10.10 (Maverick Meerkat) 64-bit desktop.
I want to make my X server listen to remote connections from clients in other machines on the local network. I know about ssh -X
and that is not what I want. I vaguely remember changing something like TCPListen
from no
to yes
, but I don't remember where this change should be applied.
I'm interested in either a GUI method or a CLI one.
PS editing /etc/X11/xinit/xserverrc
to remove the -nolisten tcp
option and rebooting does not work.

(Here follows an almost verbatim copy of a self-answer from an identical question on serverfault which I'd forgotten about; askubuntu wasn't yet created).
Based on information found in this page about enabling XDCMP and the file /etc/gdm/gdm.schemas, I managed to create a
/etc/gdm/custom.conf
file:Take care with letter case: it won't work, if you write "disallowTCP=false"... I also changed the /etc/X11/xinit/xserverrc file to:
i.e. I removed the
-nolisten tcp
options to the X executable. I don't know if I needed to. You might want to try avoiding this edit.If you only change the xserverrc file, X will nevertheless start with "-nolisten TCP".
After that, all that is needed is a restart of the gdm process:
You can verify the success as:
Update
After an upgrade to 12.04, I had the same issue. This time, the culprit is the lightdm that the system uses. The file that needs to be updated is
/etc/lightdm/lightdm.conf
and the required addition is axserver-allow-tcp=true
in the[SeatDefaults]
section.And afterwards, I also found that answer. :)
Synopsis
So, in 10.10 this still works: create
/etc/gdm/custom.conf
with contents as specified above and restartgdm
.
