[SATLUG] Dual Monitors with FC6

[Matt Kinsel]

Hi all,

I'm running Fedora Core 6 on a Sony Vaio laptop, and I've got an extra CRT
monitor that I want to use as a second monitor for my system.  My laptop has
a VGA port which I will connect the monitor to.  I used the GUI tool
"system-config-display" to attempt to configure a dual-head environment.
After I saved the settings I logged out and tried to restart my X server.
However, I received a message saying "Failed to start X server", and then I
was given the option to view the Xorg.0.log.  The first thing I found was
this warning:
(WW) No monitor specified for screen "Screen0"
Using a default monitor configuration

I also found two errors:
(EE) ATI: XF86Config Device sections "Videocard0" and "Videocard1" may not
be assigned to the same adapter
(EE)No devices detected

And after those two errors there was this message:
Fatal server error:
no screens found

That was the end of the Xorg.0.log, and then I was able to try to
reconfigure the X server settings.  After typing in my root password, the
shell output this:
Couldn't start X server on card 0
Couldn't start X server with old config, trying with a fresh configuration

After that I was given the "system-config-display" GUI tool to reconfigure
the settings.  I put them back how they were (no dual-head), and then the X
server started fine.

Well, that's how it went down. Sorry for the play-by-play details, but I
feel that the more info given the better.  Anyways, here are my
/etc/X11/xorg.conf files for the two setups:

Single head: http://docs.google.com/Doc?id=dgrrq4fk_90jjqtn5
Dual head: http://docs.google.com/Doc?id=dgrrq4fk_89dkgpnp

Could y'all help me out with this?
TIA
