[Mactel-linux-users] Problems with intel xorg driver on EFI (help needed from Fedora users)

[Mildred Ki'L. <ml....@on...>]

Hi,

I recently installed Fedora 10, and I asked specifically not to
configure any boot manager, as I feared I couldn't boot Mac OS X any
more (after reading <http://www.michaeldehaan.net/?p=794>). But it
didn't happened. Unfortunately, I didn't have any means to boot Fedora.

Still, Anaconda installed for me in
<fedora>/boot/efi/EFI/redhat/grub.efi a version of GRUB 0.9 patched for
EFI. After copying it to my EFI partition, I could boot Fedora. I used
the following commands:


root   (hd0,3)
kernel /boot/vmlinuz-2.6.27.5-117.fc10.i686 root=/dev/sda4 video=efifb ro
initrd /boot/initrd-2.6.27.5-117.fc10.i686.img


Fedora boots correctly (I can tell because of the logs I can get using
my other Linux installation), but I see nothing. Or more precisely,
after GRUB loads the kernel, I see a pure white screen. So I guess I
don't have any virtual console. After a few moment, the screen start
blinking, I can tell it's X.org starting, unfortunately it fails and I
have to reboot.

The Xorg log says:

(II) Loading /usr/lib/xorg/modules/drivers//intel_drv.so
(II) Module intel: vendor="X.Org Foundation"
    compiled for 1.5.2, module version = 2.5.0
    Module class: X.Org Video Driver
    ABI class: X.Org Video Driver, version 4.1

(II) intel(0): Integrated Graphics Chipset: Intel(R) 945GM
(--) intel(0): Chipset: "945GM"
(--) intel(0): Linear framebuffer at 0x80000000
(--) intel(0): IO registers at addr 0x90380000
(WW) intel(0): libpciaccess reported 0 rom size, guessing 64kB
(EE) intel(0): Bad VBT signature
(WW) intel(0): VBIOS initialization failed.
(==) intel(0): Using EXA for acceleration
(II) intel(0): 2 display pipes available.

...

It seems that the intel driver still uses the BIOS for initialisation (a
guess). I thought it was fixed long ago. The other drivers (fbdev, vesa)
loaded also fails miserably.

Can you see anything that could help me ?

If you have Fedora installed, where is your configuration file (I can't
get GRUB to load the configuration file automatically). Are your GRUB
command lines similar (to be found in menu.lst).

Thanks.

Mildred
