External Monitor on an iBook G4
Ubuntu 6.10 and later
For simply cloning the internal LCD to an external monitor, it is enough to slightly edit /etc/X11/xorg.conf: Disable the UseFBDev Option and add Option "MonitorLayout" "LVDS, CRT". For my iBook I also need to set an (arbitrary) horizontal and vertical frequency for the external output; if I do not do that, the internal display only starts at 800x600 if there is no external monitor/beamer connected (and thus it cannot detect its resolution). So a working Device stanza looks like:
Identifier "ATI Technologies Inc M9+ 5C63 [Radeon Mobility 9200 (AGP)]"
Driver "ati"
BusID "PCI:0:16:0"
Option "MonitorLayout" "LVDS, CRT"
Option "CRT2HSync" "30.0-86.0"
Option "CRT2VRefresh" "50.0-120.0"If you need more advanced options like Xinerama, please take a look at the following section.
Ubuntu 6.06
The following is my xorg.conf that supports an external monitor with the iBook G4 1.2 GHz. Note that I had to disable "UseFBDev". My installation is a fresh Ubuntu 6.06.

Playing videos (Overlay)
The overlay driver can only output to one device at a time, i. e. only to internal LCD screen or external monitor. However, you can switch the target on the fly with the xvattr package. xvattr -a XV_SWITCHCRT -v 0 switches to internal LCD, xvattr -a XV_SWITCHCRT -v 1 switches to external monitor.
