some questions? maybe st00pid, but need asked

[me]

I am confused. Server is f14 loaded a couple of days ago.

We go through all of the process of loading pxelinux.0 from our tftpboot
(/var/lib/tftpboot/ltsp/i386 )directory which is f10, and then booting out of our chroot
( /opt/ltsp/i386 ). So why does the f14 desktop come up vs the F10 version that we
have configured?

I have been having problems with touch screens on the TC's and found that I can drop to
a shell ( ctrl/alt f2 ) during the TC boot and cat /dev/ttyS0 then touching the screen I
get a response. When it gets to the desktop ( f14 ) then I go into a shell, cat'n
/dev/ttyS0 does nothing.

I have read and re-read, searched and scratched and can't figure out what I am missing.
Guess that the brain cells are tooooo old.

Sounds like the chroot is not being entered by the TCs. They are instead
being routed to the full OS of the server. That's a config issue in the
LTSP setup in the OS being sent to the TCs. Double check your pxe boot
process and make sure it really is what's being loaded.

That /dev/ttyS0 is on the server not the TC. Basically, the touchscreen
serial port is not being sent back to the server like a mouse device. I
don't know if serial device data is supported. The serial mouse was dropped
from the kernel long before Fedora 9 days. I about cried as my wonderful
Kensington trackball was being discarded.

Bottom of the TC states Fedora 10 - I will look at the config *again*. I went through
DMESG on the TC and F10 is in all the OS names.

I was curious so I hooked up a touch screen on the server - low and behold cat
/dev/ttyS0 responds on the TC when I drag across the touchscreen on the server. Only
the touch portion ( serial port ) was hooked up to the server NOT the monitor portion.

Other folks seem to have no trouble with their touchscreens - most of what they say is
'they just work' - go figure. Is there a way to re-assign the TC serial port to another
tty? I only have something like 5 TC's and /proc shows something like 50 tty's.
