What version of K12LTSP are you running? The 4.4.1 or the 5.0 (beta)? Look in
/etc/k12ltsp-release if you're not sure.
Just guessing here, but it sounds like it's not able to properly detect the video
card/chipset in those clients. Get the MAC address of one of the clients in question,
add it to the /etc/dhcpd.conf* file like so:
host problem {
hardware ethernet 00:90:27:b6:b9:15;
}
but use the MAC address of the client instead of the number I used. If you look toward
the bottom of the file, you'll see other examples. What you're doing here is just
assigning a name to the client so it's easier to configure what X server it loads.
After you've made the above change, restart the DHCP server ('service dhcpd restart').
Then add this to the /opt/ltsp/i386/etc/lts.conf file:
[problem]
XSERVER = vesa
Add this to the bottom of the file; there are other examples there, too. After that,
reboot your client and see what you get. What you've done is told the system that the
client with MAC address 00:90:27:b6:b9:15 and known by the name 'problem' should have
the vesa X server loaded, rather than trying to auto configure it. HTH
