[K12OSN] Resolution Config Problem

When you cannot get the mode you are after, the best thing to do is:

1. as you say, make sure the config file is being read.  One way to do
this is to set:  


in lts.conf and reboot the client.  Once the client is booted, you
should be able to press ctrl-alt-F2 to get to screen 2 and be presented
with a root shell on the client.  If you do not get a root shell, your
config file is not being read.

2. Look in the client's Xorg log file.  If you follow #1 above, and it
*does* work, from the root shell, scp the Xorg log file to the server:

scp /var/log/Xorg*log user at server:/home/user

Then, attach the log file to an email to this listserv, if you want some
help with it.  The log file will give you all the gory details of what
modes it rejected and why.  That should give you all the info you need
to adjust things properly and not to guess.  :)


PS: One other note:  in some older versions of LTSP5, you needed to add
a line:


in order for a xorg.conf file to be created from your parameters.  Try
adding that line to your pasted configuration and see if that helps.
