I have a Toshiba laptop (Qosmio F20) running FC4. It has a nvidia
graphic card (GeForce 6600) and I installed the nvidia drivers from
nvidia site. Works fine.
But I didn't find how to use both lcd panel and projector with this
laptop. I must have two xorg.conf files: one for the lcd panel and one
when I want to use a beamer; in that case there is no display at all on
the lcd panel.
Does anybody know how to configure xorg to have both display.
Thanks a lot.
Two points here:
1. Default video mode for laptop cards are sometimes BIOS settable.
2. Default video mode for every video driver may be different.
The radeon driver will 'mirror' the video to the external vga adapter.
In this mode, just plug in the projector and it will be a mirror of the
screen display. HOWEVER, any application that uses direct access to the
video card (such as a video player) will not send it to the projector.
The commercial ati driver fglrx, does NOT mirror the display by
default. However, if I use the laptop CRT/LCD buttons to switch to
external, then start X, it will even do videos.
Steps with fglrx driver:
sudo init 3
close up and head to meeting
plug into projector
hit CRT/LCD button -- for DELL Latitude D600 is <Fn>F8
I now see my display on the projector
sudo init 5
