[ltp] Videoswitching with i810

[Václav Štěpán]

CRT is the analog device you plug in into the VGA-out (Beamer, external
LCD, whatewer). DFT would be (IMHO) an external digital device - but you
would need a DVI output for that. LFP is the internal LCD flat panel.

The i810 tool and the xorg.conf setting work on different levels.
The xorg.conf settings direct the X-server to run on two pipes and
connect CRT to the first and LFP to the second and to display the
same on both.

Using X config you can as well get to an extended display setup -
you will get two independent screens.

i810 switches the output on a lower level. The settings in xorg.conf
are IMHO not needed/it's a different thing.
