Hi Wolfgang,
>From the XDMCP documentation:
*Hostname*: ARRAY8
Is a human readable string describing the host from which the packet
was sent. The protocol specifies no interpretation of the data in this
field.
*Status*: ARRAY8
Is a human readable string describing the status of the host. This
could include load average/number of users connected or other information.
The protocol specifies no interpretation of the data in this field.
Looking at the LightDM code we don't set anything in these fields. It seems
we should probably set hostname to the system hostname (and make
configurable in lightdm.conf). Not sure what is appropriate to set status
to (if anything).
