To enable the XDMCP server in LightDM edit /etc/lightdm/lightdm.conf and add the following section:
|
|
|
|
[XDMCPServer]
|
|
enabled=true
|
|
|
|
Then restart LightDM with sudo restart lightdm from a text console (logout from any graphical sessions first).
|
|
|
|
You can set the XDM-AUTHENTICATION-1 key by setting key=value (value is in the same format as is used in the X -cookie option). If the key is not set then no authentication is used.
|
|
|
|
You can change the UDP/IP port by setting port=1234.
|
|
|
|
All the available LightDM settings are shown in the example configuration in /usr/share/doc/lightdm/lightdm.conf.
