OK, So ive got my system set up and I was trying to add a cool startup screen :)

But everytime I start it no bootsplash, dmesg just wields the dreaded "color depth mismatch (15)" message. Here are the steps I took:

-Downloaded the latest gentoo-dev-sources
-ACCEPT_KEYWORDS="~ppc" emerge bootsplash
-Followed the 'splash -s -f .....' instructions for the default theme at 1024x768 and 1280x1024, also tried a different theme.
-added the line "append="video=aty128fb:1024x768-32 splash=silent"" to yaboot.conf, did ybin.

Now my fbset -i says im using ATY,Rage6a (and a mode of 1280x1024) so i tried switching to atyfb to no avail. Has anyone got this to work using A dual g4 450? Its a 17" CRT Studio Display.Ive also made sure everything that should be compiled into the kernel are in there and things that arent arent.

Any ideas? Or at least a step in the right direction b/c Im stumped.

Also when i do "splash -s -u 0 /path/to/config" nothing shows up, its just brings up the prompt ie :
Code:

# splash -s -u 0 /path/to/config
#


No error message or anything .

Bootsplash only works with the VESA framebuffer. Good news is that all newer video cards are VESA compliant. To Fix this:
Code:

cd /usr/src/linux
make menuconfig

Uncheck ATI Rage 128 from the frambuffer section and check VESA VGA as built-in, not as a module. Recompile the kernel, then look here:
The Framebuffer Howto

Not anymore. Read up on it on the Bootsplash on PPC thread.

VESA defines function calls to to the VGA BIOS. There is no BIOS on ppc and therefore no VESA.

gfs, did you try other color depths in your yaboot.conf? Instead of 32 you can try 15, 16 and 24. Also, if you are running on a resolution of 1280x1024, you will need to change the resolution in the append line in your yaboot.conf to 1280x1024.

hth,

Wow, learn something new everyday :) I'm going to have to read up on Apple's new stuff, or better yet, buy one. I've been stuck on x86 way way too long. Also it was my understanding that most BIOS's even Apple's method had a setting for a primary graphics device on boot up. If set to AGP, thr AGP's BIOS boots before the system BIOS

It might also help if i had the right info ...)(d'oh!)
After some frustration and research it would appear that ATY,Rage6 corresponds to an Apple OEM Radeon 32MB AGP card NOT the rage 128. (Which may explain some x related issues i was having.) I will change the settings around and let you know, thanks for all the suggestions.

OK, Ive tried switching the driver to radeonfb and trying 15,16 & 24...24 Yields the 'depth mismatch' message and 15 and 16 turn the screen black in verbose and silent modes. ( The screen just goes blanks if i wait for it to boot and log in (blindly :) ) and type startx gnome starts up fine ....
