SDDM always starts X with '-nolisten tcp'

[RAMeijer]

I would like to use SDDM but had to switch back to LightDM as I could not find a way to turn off the option '-nolisten tcp' and I need to be able to connect to my X from remote machines...

The only places I can find any reference to that option are the binary itself and the log file:

[root@x-ray ~]# locate sddm|xargs grep -lr nolisten
/usr/bin/sddm
/var/log/sddm.log

Am I missing something?

Not a developer of sddm, but a quick grep throught the sources for "nolisten" only finds on instance:

src/daemon/XorgDisplayServer.cpp: << "-nolisten" << "tcp"

So a patch is easy, though a compile time option or ideally a config setting would be better, imho.

We need to get the xorg startup arguments from sddm.conf. I think this should be in 1.0 tbh, but it'll depend if anyone wants to pick it up. Marking.

[edit] Solution:

sudo nano /etc/lightdm/lightdm.conf

[SeatDefaults]
xserver-allow-tcp=true

OR (OS dependent)

/etc/sddm.conf

[X11]
ServerArguments=-listen tcp -dpi 96

[original comment]
I've just spent several hours trying to figure out why my desktop wont allow me to '-listen tcp' ...and which files even determine this. But I am no closer to a solution. Did someone revert something in Kubuntu 18.04?
