X-Server

This is my xorg.conf-file for single-head setup (only the display of the flybook).

This is my xorg.conf-file for dual-head setup (display of the flybook and another independent external display).

This is my XF86Config-4-file for single-head setup (only the display of the flybook).

This is my XF86Config-4-file for dual-head setup (display of the flybook and another independent external display).

The TV-out should be configurable with the program atitvout. Unfortunately it doesn't work with the chipset in the flybook.

I discovered a program called radeontool. With this you can control the backlight, the different video outputs (I didn't have the time to test the TV-out yet) and change virtual resolutions on-the-fly.

With kernel 2.6 both axes of the 'mouse' are inverted, so you need these lines in you XF86Config-4:
Option "InvX" "true"
Option "InvY" "true"

To activate xinerama extensions you have to uncomment the line
Option "Xinerama" "on"
in the file XF86Config-4.dualhead

The XRandR extensions are automatically activated when starting the X-server.
Unfortunately they only let you change the screen resolution on-the-fly with a program called xrandr (disabling xfree86-dga is NOT necessary, as mentioned in other documents), rotation and reflection of the screen do not work (yet).

DRI with the radeon-driver only works in singlehead mode.

There is a module radeon.o in the kernel and a module radeon_dri.so for XFree86 to get 2D/3D acceleration.

The PAN-Button can be used as the middle mouse button.
