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.
