I'm reading many docs, on /usr/X11R6/README for macppc there is "You need to set machdep.allowaperture to 2 in /etc/sysctl.conf" and this is done.
I ran the command 'X -configure' and now I have 'xorg.conf.new', but default driver is 'radeon' and doesn't work, I have changed it with 'ati' and now works but seems to be instable. ctrl + alt + backspace to kill X server doesn't work. -- luca suriano
