You can get 1024x768 on an Apple Studio Display 17" by putting the following
Modeline in your XF86Config-4 in /etc/X11:
Modeline "1024x768" 112.62 1024 1068 1240 1420 768 768 780 808 +hsync
+vsync
I have been unable to get 800x600 on this monitor ,,, but I think 1024x768
should be pleasant enough :)
If you want to get the console into 1024x768, then edit /etc/fb.modes and put
the following lines in there:
mode "1024x768-99"
geometry 1024 768 1024 768 8
timings 8879 182 34 28 0 176 12
hsync high
vsync high
endmode
also, assuming you have the fbset-2.1-6 package installed (if not, get it
from
ftp://ftp.yellowdoglinux.com/pub/yellowdog/yellowdog-2.1/ppc/YellowDog/ppc)
... you can edit your /etc/rc.local file and add the following line at the
end:
/usr/sbin/fbset 1024x768-99
This should put your console in 1024x768 mode on bootup. WARNING! This will
only work for Apple Studio Displays, so if you have something else don't try
this!.
