iMac (imac-netstatz) wrote on 2015-04-27: lightdm tcp listen requires additional configuration

In order to enable X11 forwarding from an external host you must explicitly set the Xserver to listen by overriding the xserver-command. Previously you could set the xserver-allow-tcp=true and it would do this automatically.

I would have expected this change in behaviour to show up in README.Debian.gz but since it did not, perhaps the functionality of the "xserver-allow-tcp=true" is not working as expected.

Below shows my before (no TCP listener on 6000) and after (TCP listener on 6000) lightdm.conf to re-enable the listener after the 15.04 upgrade.

Before (14.10):

~$ cat /etc/lightdm/lightdm.conf

[SeatDefaults]
xserver-allow-tcp=true

After (15.04):

~$ cat /etc/lightdm/lightdm.conf

[SeatDefaults]
xserver-command=X -core -listen tcp
xserver-allow-tcp=true
