Dual Head

Hi all

SYSTEM: Fedora Core 3 Heidelberg
DISPLAY CARD: ATI RADEON S300 w 128Mb, VGA, DVI, TVOUT

I can run X in Dual Head mode but only when I do it like this:

>Boot with configuration file (xorg.conf) in single head mode
>login
>change to dual head with system-config-display
>logout
>login

If I happen to forget to put the xorg.conf file back in single head mode before rebooting or if the system hangs and I have to restart manually (power), it WILL not start and I have to use knoppix or the fedora rescue mode to mount the filesystem and replace the xorg.conf file.

This is very annoying and I would like either

>A solution

or

>A hack that can put the xorg.conf in single head mode BEFORE X is started on boot

With kind regards

Don't know of a solution but here is a hack that might help...

Create a singlehead_xorg.conf
Create a script in /etc/init.d which copies singlehead_xorg.conf to xorg.conf (cp -f /etc/X11/singlehead_xorg.conf /etc/X11/xorg.conf)
Add links to run this script before starting X (ln -s /etc/init.d/copyscript /etc/rc.d/rc5.d/S##copyscript)
You will need to replace ## with a number that makes sense but you are probably safe putting in at the same level as network.

Ooops.... Fedora don't like that

Boot hangs when I do that, maybe because Fedora uses the X-Window system while booting.

For this to work, it should be executed before the booting goes to the graphical mode.

You should know that, as opposed to Red-Hat, Fedora goes to graphical mode during boot to display a progressbar of the global boot process.

< I believe the graphical mode during bootup isn't X, it is framebuffer. >

Maybe so, but it definitly uses the xorg config file because the 2nd monitor is blacked-out if the system is in dualhead mode, and a clone of monitor 1 if the system is in singlehead mode. Which means that framebuffer or X, it uses xorg.conf

Anyway, I'm going to do a test in a few hours...

Guys,

I made a little mistake in rc.local

I put in

echo -n "Putting system in singlehead
rm .. blabla
echo " done"

And it so happened that it was interpreted by echo

This means that:

The FIX to the problem I was having is:
==================================
In /etc/inittab, change
id:5:initdefault: ====> id:3:initdefault:
Add the following into /etc/rc.d/rc.local
init 5 <=== continue to graphic mode
==================================

Thanks Wesley. the system boots correctly now, regardless of single head or multihead in xorg.conf

>thank you also jeiler for your participation

I meant that the file was not deleted because the command 'rm -f xorg.conf: ls -s xorg.config.singlehead xorg.conf was not executed by the system but interpreted by the ECHO command. It means that my system booted correctly with dualhead mode activated.
