[gentoo-ppc-dev] External Monitor on ibook2/Rage128

[Stefan Boresch]

Hi, 

does anyone have hints/suggestions how to use an external
monitor (i.e., => beamer) with an ibook2 having an ATI Rage128
card (not radeon!).  I am running a kernel compiled from
the linux-2.4.20-ppc-r2 sources, xfree 4.2.99.4, and the
drm module is the one from xfree-drm (not the kernel!)

My "successes" to date are as follows:

(1) Use the XF86Config generated by Xeasyconfig, modified for a
german keyboard. Boot without external monitor. Hook up monitor,
and activate the external display with m3mirror. The LCD screen is
mirrored, but the picture wobbles horribly; no way you can give
a presentation that way :-(  BTW, both X and the console
have this wobbling!

(2) Boot with the external monitor. Now m3mirror can mirror
the console without problems, but once you go into X colors and
sizes are totally off (the picture looks like a distorted
640x480 with virtual 1024x768 screen, color is brownish when
it shoul be grayish etc) :-(

(3) Revert to plan (1) [no external monitor during boot], but
extend the XF86Config file to have
two ServerLayout->Screen->Monitor sections, and wrap everything
in a script to switch (m3mirror) between LCD and external monitor
[this just to be on the safe side when trying eg 1280x1024
resolutions externally].  I think my basic XF86Config approach
is OK since I can force the system eg to 1280x1024 resolution
on th external monitor, *but* again there are way too many
distortions to make this usable :-( Combining this extended
XF86Config with (2) doesn't produce anything usable either :-(

Any hints/hacks appreciated,

stefan
