Hi Ken,
I do it in the following way:
I have two scripts in /etc/trinity/tdm
1st script - name xrand.sh
#######################################################################
#!/bin/sh
# usage: xrand.sh start|stop | Monitor-Typ
case "$1" in
stop)
/usr/bin/xrandr --output VGA1 --off
;;
X193W)
# for an Acer x193W
/usr/bin/xrandr --output VGA1 --mode "1440x900" --left-of LVDS1 \
--output LVDS1 --mode "1024x768"
;;
L1800P)
# for an LG Flattron L1800P mit identischer Auflösung wie Laptop
/usr/bin/xrandr --output VGA1 --mode "1024x768" --right-of LVDS1 \
--output LVDS1 --mode "1024x768"
;;
text)
# LG Flattron L1800P rotated for work with text documents
/usr/bin/xrandr --output VGA1 --mode "1280x1024" --rotate left \
--left-of LVDS1 --output LVDS1 --mode "1024x768"
;;
*)
echo $0 stop | X193W | L1800P | text
;;
esac
########################################################################
The 2nd script - name getMonitor.sh
########################################################################
#! /bin/bash
# x193w and l1800p are the names of the motiors written out in
# Xorg-log-file
grep -i x193w /var/log/Xorg.0.log > /dev/null
if [ "${?}" == "0" ]
then
# found Acer monitor - set resolution
/etc/trinity/tdm/xrand.sh X193W
exit
fi
grep -i l1800p /var/log/Xorg.0.log > /dev/null
if [ "${?}" == "0" ]
then
# LG 1800P fund - set resolution
/etc/trinity/tdm/xrand.sh L1800P
exit
fi
########################################################################
This scripts will be called from Xstartup also located in
/etc/trinity/tdm. The skript starts with:
#! /bin/sh
# Xstartup - run as root before session starts
if [ -e /etc/trinity/tdm/getMonitor ]; then
/etc/trinity/tdm/getMonitor
fi
....
So what does it do?
On startup it looks, if the acer (or the LG) is conneted to my lenovo
laptop, and if so the wantet resolution and screen-positon (left or
right of) will be set.
After that you can see multi monitors in trinity contol center.
Hope that helps and
merry christmas and a happy new year
