Philip,
I am using a slightly unsavory solution for picking dual / single head.
I've got two xorg.conf files in /etc/X11 - xorg.conf.single xorg.conf.dual
Then I added an entry in my grub.conf (bootloader) for dualhead - it has
an extra parameter that is passed to the kernel - "dualhead".
I also create a script that runs in /etc/init.d - xheadconfig (posted
below).
This script checks /proc/cmdline to see if I specified dualhead and then
selects
the correct x setup. As I said - a bit unsavory, but its better than
logging in as
root and selecting your setup by hand...
What do you think?
#!/bin/bash
#
# xheadconfig This shell script links the correct xorg.conf file
# depending on the kernel parameters passed.

RETVAL=0
start() {
# first check if xorg.conf is a symbolic link
# I would not want to clobber my real xorg.conf file!
if [ ! -h /etc/X11/xorg.conf ]; then
echo "xorg.conf is not a link - will not do anything"
exit 1
fi
# now see if the single or dualhead setups are available
if [ ! -f /etc/X11/xorg.conf.single ] || [ ! -f
/etc/X11/xorg.conf.dualhead ]; then
echo "One of the single / dual head setup files is
missing."
exit 1
fi
# figure out from kernel parameters what we have to do!
cmdline=$(cat /proc/cmdline)
if strstr "$cmdline" dualhead; then
cd /etc/X11/
ln -f -s xorg.conf.dualhead xorg.conf
else
cd /etc/X11/
ln -f -s xorg.conf.single xorg.conf
fi
}
case "$1" in
start)
start

stop)

*)
echo $"Usage: $0 {start|stop|status|restart|reload|condrestart}"
exit 1

HI Albert, Alex, Tim and the gang,
So I've been happily using dual head now for 2 weeks. Everything's
stable. Thanks for this, it has improved my productivity greatly.
Now for remaining issues, I hope this helps. Feel free to use me to test
suggestions...I'll do what I can. BTW, I've confirmed both of these with
Albert (another T23 dual head user).
1) glxgears is black on Screen 1 (with or without no ScreentoScreen XAA)
2) exiting dual head leaves both monitors powered off. Fn-F7 required to
power on the main LCD again.
Thanks again,
Phil
P.S. Anyone know if there's a wrapper out there that uses X --probeonly
or something to see if there's actually another 'head' attached and then
start the server with the appropriate 'layout'? When I took my laptop
home this weekend, I had windows in never-never land...and the damn
gnome-window applet's are sooo broken.
