# By JettLogic

# This is an x.org config for an August 2005 iBook G4 12" on Gentoo
# Linux, using non-accelerated radeon driver.  It provides layouts for
# cloning of the screen to an external 1280x1024 display, and
# extending the desktop on to the external 1280x1024 display (on the
# left) using the radeon display extender.  

# It also needs Xinerama so that you can scroll up/down on the
# 1024x768 internal display (the viewport width is the sum of the
# displays, but the height is the same as the largest to make it
# rectangular, which is taller than the small screen can show at
# once).  There is some flicker when doing the scrolling.
