iBook G4 X question

[The old drifter]

I have seen, I can't remember where in these forums, someone claim that he or she has his or her iBook G4 running with millions of colors at its highest resolution. I have not suceeded in doing so yet. I wonder if anyone who has succeeded in doing this might be able to post his or her X configuration files.

Thanks in advance.

Hello Adam.
I am new to yellow dog myself, and installed it on my ibook yesterday.
Mine would not work with highest res and millions of colours out of the box either (this is quite poor considering the limited range of hardware YDL has to cater for).

I assume you have a G4 ibook with radeon 9200 mobility.
Anyway, there is no need for you to recompile anything. You just have to change your Xconfig... Here is mine:

Code: Select all

# File generated by Xautoconfig.
Section "ServerLayout"
   Identifier   "XFree86 Configured"
   Screen      0  "Screen0" 0 0
   InputDevice   "Mouse0" "CorePointer"
   InputDevice   "Keyboard0" "CoreKeyboard"
EndSection

Section "Files"
# RgbPath is the location of the RGB database.  Note, this is the name of the
# file minus the extension (like ".txt" or ".db").  There is normally
# no need to change the default.

# Multiple FontPath entries are allowed (they are concatenated together)
# By default, Red Hat 6.0 and later now use a font server independent of
# the X server to render fonts.

       RgbPath      "/usr/X11R6/lib/X11/rgb"
       FontPath     "unix/:7100"
EndSection

Section "Module"
   Load    "GLcore"
   Load   "dbe"
   Load   "extmod"
   Load   "fbdevhw"
   Load   "glx"
   Load   "record"
   Load   "freetype"
   Load   "type1"
   Load   "dri"
EndSection

Section "InputDevice"

# the deprecated adb keycodes.
   Option      "XkbRules"   "xfree86"
   Option      "XkbModel"   "macintosh"
   Option      "XkbLayout"   "us"
EndSection

EndSection

EndSection

EndSection

EndSection


The parts that matter:
Make sure dri, glx and GLcore are loaded in the modules section.
Make sure that the radeon driver is used.
Make sure that the options for AGP and usefbdev are enabled
Make sure defaultdepth is set to 24 (millions of colours)

Hope this helps you out (and anyone else struggling with the same problem).

Let me know if it works.
