[K12OSN] K12Linux F10 Display problem

Which leads me back to my original thing with K12LTSP.

Their early documentation stated that it was designed so that entities could take advantage of their older hardware and not have to upgrade all the "computers" to get the latest software. I took this to mean just that. I can use my older hardware, and just upgrade the "server" and let 'er fly. That has not been the case, however. . .

I had some terminals that worked GREAT under FC3 (with a bit if tweaking in the configs) and one of them was a 486-DX40 with 24MB of RAM. It did everything the grandyounguns wanted to do.

Next version, I could no longer get that one to work.

I do realize that a 486 is archaic and it wouldn't really hurt my feelings to not use it, but from the get-go, the system was designed to be able to use older hardware and not upgrade every time you turn around. With each new distro, it seems to be getting farther and farther away from that model.

We are still running K12LTSP release 4.2.1EL-1
2 Servers with about 100 concurrent  users.
This setup has served us well and has been hands off for three plus years.

I plugged in the k12 live usb (pretty slick) and booted a few of the lab 
terminals with mixed results.
We have a mixture of  CRTs and LCDs and some of them will not display.
The clients are all Compaq DS51 and DS5S
We ran into the same problem when we demoed the latest ubuntu a few 
months back.
I'm guessing that the newer x servers don't work well with the older 
hardware we have and it has nothing to do with a particular 
distribution. It's looking like we will have to dig in and make some 
manual adjustments to the display properties.
I'm looking around /opt/ltsp/i386/etc/X11 but it is not obvious where I 
should make changes.
