Trying this


After modifying /etc/gdm3/custom.conf content by adding ServerArguments=-listen tcp. I got xserver running on port 6000

[security]
DisallowTCP=false

[xdmcp]
ServerArguments=-listen tcp

as per
https://askubuntu.com/questions/672180/x-server-started-with-nolisten-tcp-in-spite-of-disallowtcp-false-in-etc-gdm


Doesn't work

A 'real' X server might have to configure XDCMP
https://help.gnome.org/admin/gdm/stable/configuration.html.en

i think XDCMP is for transferring the entire desktop to another X server
we don't really want that

Might need -listen tcp added...


sudo mv /usr/lib/xorg/Xorg /usr/lib/xorg/Xorg-safe

Replace with

```bash
#!/usr/bin/env bash

/usr/lib/xorg/Xorg  -listen tcp $@
```

BAD things happen if you change this file
boot loop without tty access
