jeff,
Certainly it's possible. In fact, it probaby wouldn't be all that hard.
One of the first things the 'startx' screen script does, is grab the
variables from the lts.conf file.
You could add code after the call to get the options, that displays a
menu. Something like this:
LTSP Screen Resolutions
1) 1024 x 768
2) 800 x 600
3) 640 x 480
Please enter a selection (1,2,3):
Then, they select 1, 2 or 3, and the script internally sets
the X_MODE_0 variable to either "1024x768", "800x600" or "640x480".
Here's the code that you can add to the top of the startx script:
====================================================================
if [ "${X_MODE_0}" = "ASK" ]; then
X_MODE_0=""
while [ -z "${X_MODE_0}" ]; do
clear
echo "LTSP Screen Resolutions"
echo
echo " 1) 1024 x 768"
echo " 2) 800 x 600"
echo " 3) 640 x 480"
echo
echo -e "Please enter a selection (1,2,3): \c"
read MODE
case "${MODE}" in
1) X_MODE_0="1024x768"
;;
2) X_MODE_0="800x600"
;;
3) X_MODE_0="640x480"
;;
*) echo "Invalid selection!"
sleep 1
;;
esac
done
fi
===================================================================
All you need to put in lts.conf is:
X_MODE_0 = ASK
And it will ask the user what resolution they want.
it will get much trickier if you need to specify custom modeline info
for the monitors, I'll leave that for an exersize for you.
