** Description changed:
Hi,
PROBLEM:
- I tried use xdmcp (startx) script in LTSP to connect in a remote X server and
it not work. Although using the package for Ubuntu.
- I checked that the same occurs in the packet with the ltsp 5.4.5 source code,
independent of the distribution.

lts.conf
[00:11:22:AA:BB:CC]
SCREEN_07=xdmcp
XDM_SERVER=x.x.x.x
When thinclient boot, the XDM_SERVER value is ignored.
I found a bug in screen_session script, line 78 (or was it in bash?). It
calls a script with $args variable as argument between double quotes:
78: "$script_path" "$args"
In xdmcp script lines 19-23, exists a condition, based in number of
arguments:
19: if [ $# -lt 1 ]; then
20: X_ARGS="$X_ARGS -query ${XDM_SERVER}"
21: else
22: X_ARGS="$X_ARGS $*"
23: fi
Even without arguments, in this case, $args empty, bash/sh return 1 as
total arguments in $# variable, because of the double quotes used in
screen_session script.
So the condition will always be FALSE, ignoring XDM_SERVER value.
SOLUTION:
change session script line 78 to:
78: "$script_path" $args
or
78: eval "$script_path" "$args"
