[Mactel-linux-users] EFI booting

[Brandon K. <bdk...@gm...>]

I have repeatedly booted a Macbook Pro 3,1 in pure efi mode with very
few problems. 

I used grub-efi and compiled it from latest svn using
./configure --with-platform=efi --target=x86_64. 
Without refit. 

The only big thing that does not work yet is the framebuffer, 
so right now I have no text output until the system is booted. 

I have tried using FB_EFI (which I had expected to not work because it
is a GOP driver), 
imacfb, vesafb and uvesafb. 

Both vesafb and efifb display text, however I get three columns of 
text that is all very small print that is unreadable. 

Has anyone else experienced the same problem, or am I in 
uncharted territory because it is x86_64 and an nvidia graphics card?

I also cannot use pommed because it uses bios calls to change the 
screen brightness. (Everything but brightness works fine, even
applesmc). 
I also tried a kernel backlight driver, macbook_mbp.c however this was 
just ripped off from pommed anyways. 

Any word on this would be a great help.

Over here I'm using grub2
not sure if there similar, anyways
try vga=790 as a boot option, and try compiling the
fb module "in the kernel"(say "Y") rather than a "module" ("M")
the text is funky when compiling fbcon as a "M", as opposed to
having it built in.

Thanks, I will give this a try. (Is your video card nvidia? I don't
think it should matter; however, I read somewhere that grub2 attempts to
initialize video bios and figured that it was specific to intel as
opposed to nvidia).

I've a macbook with the ATI chipset.
As for grub2, not sure what they did with that.
you can also put "debug" in the command line as well.
This way you have fbcon starting up(with either a black and white tux
or color), then loads of info shoots out, so people stare in awe....
at the local starbucks. ; )
