We are having a problem getting anything but the default 800x600
resolution on our Netier XL1000 thin clients. These clients use a trident video chipset which we know works at 1024x768 on our old LTSP Fedora 6. We have just installed K12Linux on a new server with F11. No matter what we have tried in the /opt/ltsp/i386/etc/lts.conf file the resolution stays
the same.
You want to use the lts.conf file in /var/lib/tftpboot/ltsp/i386/, IIRC the file in /opt/ltsp is the old location, and isn't used anymore. Try adding X_MODE_0 = 1024x768 to that file. Sometimes this happens because it is detecting the video chipset wrong and using a lower resolution. If you and a shell on one of the client screens you should be able to check what it's using. You can specify X_COLOR_DEPTH = 16 and XSERVER = trident if it still won't give you the right resolution. I think it defaults to 24 bit color on Fedora, which causes a problem for some older video cards, especially at higher resolutions.

a couple questions:
1. How does one tell if the /opt/ltps/i386/etc/lts.conf file is being read? 2. Once lts.conf is configured (or edited) what must be done to read file?
   a. client logout
   b. client xwindows restart (how?)
   c. client reboot
   d. ltsp server reboot
