I have not been able to figure out how to send client syslog messages to
the server, but I just compared the server syslog file from a case where
the client got to a logon screen against a case where the client went
from the splash screen to a blank, black screen.
The logs are essentially the same to the point where I inserted a dash
line, and the good-boot log continues with an ldminfod entry. (See below)
The man page of ldminfod says:
DESCRIPTION
ldminfod will output the login sessions and locales
available. it is
usually run from an inetd(8) instance. it is used by ldm(1) to
remotely
determine available login and locale settings.
EXAMPLE
add the following lines to /etc/inetd.conf(5):
9571 stream tcp nowait nobody /usr/sbin/tcpd
/usr/sbin/ldminfod
(I think /usr/sbin/ldiminfod is on the same line as 9571.)
On the LTSP server, /etc/inetd.conf only has one line that is not
commented out:
9571 stream top nowait nobody /usr/sbin/ldminfod
Does this add anything to help someone see what's going on?

I thought I might be working through my last few big problems, but
instead I found another one.
After installing Lubuntu Quantal on a newly formatted disk and setting
up LTSP some weeks ago, I have been working only with a certain
two-machine test setup. In contrast to past troubleshooting, I have
not been swapping in multiple server or client machines.
But to address something I was working on, I tried a different client,
and this one failed to boot altogether. Then I tried a couple more
different clients (different makes/models), and they had the same
behavior. That behavior is that after the client displays the blue
splash screen, which then drops to black-and-white (normal behavior, I
think), it then goes to a blank (black) screen. It does not display
the GUI login screen.
If in lts.conf I set SCREEN_07=shell, then I can successfully log in
to a shell. I also see there among the on-screen boot messages
"Starting load fallback graphics devices [fail]."
The last entry in dmesg also refers to the above failure.
The only client that works displays a (boot) message on/through the
splash screen: "lpc_ich 0000:00:1f.0: I/O space for GPIO uninitialized."
Anyone recognize this problem?
