The multi-head options are different with each video card. You can try doing a "man drivername" where drivername is the name of the X11 driver you are using. For me, man radeon shows me the dual head options that I needed to manually add to the X config file.
My bad, it's actually a nvidia chipset. I managed to get in touch with a fellow Toshiba owner, Ulrich Hertlein[1], who also had a nvidia chipset. He spewed out his xorg.conf and I stole the following lines which now does the trick.
Option "ConnectedMonitor" "DFP,CRT" Option "TwinView" "true" Option "TwinViewOrientation" "clone" Option "MetaModes" "1024x768,1024x768" Option "SecondMonitorHorizSync" "31.5-90" Option "SecondMonitorVertRefresh" "60"
The secrect I believe is the BIOS option which is lightly documented in any Linux Laptop howto/faq, which is something that Ulrich discovered.
While the idea of "multi-head" configuration is clear I think we have
hera e different problem: I do not really use multi-head in the sense of
displaying different things on different (=internal and external) monitor
but just displaying the very same content on both screen - just the "normal"
Laptop behaviour for doing presentations. This worked on all my previous
Laptops without any spcial configuration of X.
I'm sorry that my email isn't clear, but I am to having the same thing appear on my LCD and CRT/Projector. Which is what the following line in XF86Config-4 provides:
Option "TwinViewOrientation" "clone"
"clone" means show the same thing on both screens. It has other options, like RightOf etc.
