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

i change my /usr/share/lightdm/lightdm.conf.d/50-xserver-command.conf
before it was:

i haven't /etc/lightdm/lightdm.conf
when i tried to create it and write the lines above it was worse, my system didin't start.
after a few experiment i have found something that works:
i change my /usr/share/lightdm/lightdm.conf.d/50-xserver-command.conf
before it was:
[SeatDefaults]
# Dump core
xserver-command=X -core
now:
[SeatDefaults]
# Dump core
xserver-command=X -core
xserver-allow-tcp=true
and it works! |
[Impact]
xserver-allow-tcp=true option no longer works with X.org 1.17.
[Test Case]
1. Edit /etc/lightdm/lightdm.conf and set [SeatDefaults] xserver-allow-tcp=true
2. Start LightDM
3. Attempt to connect to the X server using TCP
Expected result:
Able to connect
Observed result:
Unable to connect
[Regression potential]
Low. X.org changed their default behaviour from listen by default to listen if "-listen tcp" is passed as a command line flag. This is just the equivalent change in LightDM. Since this is a new flag to X.org if a user was to use another X server there is a risk it would not understand that flag. However it seems unlikely since X.org is the only actively developed X server. |
