To get dual-head output on a recent Intel integrated graphics card, such as
the 965 GM inside my Lenovo T-61 laptop, when running Fedora 10, only one
relatively non-intuitive step is needed. The virtual desktop size must first
be increased inside xorg.conf
so that both screens can fit inside the single X
framebuffer:
Section "Screen"
...
SubSection "Display"
...
Virtual 3072 1680
EndSubSection
EndSection
Once this is done, you can plug in a display (say, a projector), go to the “Resolution” preferences applet, and enable the new display at a reasonable resolution. F10’s version of OpenOffice.org even has a fancy two-screen presentation mode that shows a countdown timer, the next slide, etc.
