Comment 13 for bug 40973

well as said before the automatic x configuration for the iBook G3 Graphite / SE 466mhz
on the dapper desktop cd has a little bug .. it assigns to the hsync parameter a wrong value

to get it working open the apropriate file with "sudo nano /etc/X11/xorg.conf"
and change the line containing HorizSync to "HorizSync 20-40" save the file
and restart x/gnome with ctrl-opt backspace

now the video shouldnt be distorted anymore :)
