[LightDM] xserver-allow-tcp

[Ronald Hoogenboom]

lightdm-1.10.5-2.fc21.x86_64
xorg-x11-server-Xorg-1.16.3-2.fc21.x86_64

Lightdm puts the -[no]listen tcp command line option for the X server 
depending on the xserver-allow-tcp config setting (true or false). Since 
the last yum update, the Xorg server does not accept the undocumented 
-listen option anymore and exits with status 1. I am forced to set 
xserver-allow-tcp to false and therefore cannot have my remote x clients 
connect anymore.

There seems to be no way to completely omit either -listen or -nolisten 
option.

Obvious workaround could be to make a wrapper script for Xorg, but it 
would be nicer if this would be handled properly in lightdm.
