Re: [gdm-list] gdm-list Digest, Vol 119, Issue 1

[anonymous <johnandsara2 cox net>]

check the simple things first:

gdm should decide whether to show a host chooser after X startup but 
before you see anything "before light" (which is what xdm does - before 
login not after, since every X11 display host has it's own login of course)

insure you can telnet to localhost (or out), insure X ports are not 
firewalled locally.  redhat used to use a --no-tcp setting that blocked 
packets locally but NOT remotely (local used socket).  insure your using 
socket, and /tmp/.X11 (stale session files) are "cleaned" by 
/etc/init.d/?Xstuff?

gdm starts and listens for X connections, X in turn (if started with 
-query) looks for host running gdm (however, settings files may alter 
that).  finally: when gdm gets an X connection it starts a new X session 
, runs greeter, (it decides if greeter runs, if the binary is present 
and asked to run by settings), once a connection is made to the right 
host/X11 server by greeter, it shows a login (if you are not setup for 
"no login default user"), and then after longin launches (gnome3 or what 
have you desktop).

so there you go, your issue is likely port blockage, stale session 
files, or gdm is not running before X (your gnome destkop startup script 
is missing?), or you didnt select the option to show 'chooser' at startup

personally i've never seen gdm have an issue not showing remote 
connections (many years ago) it seemed to do that always, and it's a 
matter if point and click to see other hosts (assuming no ports are 
blocked).

you should ask the question on a web forum (phorum) for your linux/bsd 
distribution (ie, redhat, freebsd, debian, et al) because this is where 
people are who wrote the startup scripts, know where they are, and know 
of where to set certain settings like "show chooser before/after login".


Good luck and happy 4th!
