I´ve just managed to get the 12.04 LiveCD to boot into a GUI on my
MacBook Pro 5,2
/sys/class/dmi/id/bios_vendor:Apple Inc.
/sys/class/dmi/id/bios_version: MBP52.88Z.008E.B05.0905042202
/sys/class/dmi/id/bios_date:05/04/09
/sys/class/dmi/id/sys_vendor:Apple Inc.
/sys/class/dmi/id/product_name:MacBookPro5,2
/sys/class/dmi/id/product_version:1.0
/sys/class/dmi/id/board_vendor:Apple Inc.
/sys/class/dmi/id/board_name:Mac-F2268EC8
/sys/class/dmi/id/board_asset_tag:Base Board Asset Tag#
/sys/class/dmi/id/chassis_vendor:Apple Inc.
/sys/class/dmi/id/chassis_type:8
/sys/class/dmi/id/chassis_version:Mac-F2268EC8
I had to add the following to the grub menu entry prior to booting:
outb 0x728 1
outb 0x710 2
outb 0x740 2
outb 0x750 0
set gfxpayload=keep
linux /casper/vmlinuz file=/cdrom/preseed/ubuntu.seed boot=casper
quiet splash nouveau.noaccel=1 --
I also made sure that the Power Saving settings in OS X were set to
¨Performance¨.
The screen initially goes black before eventually flickering and then
showing the gui desktop. Adding blacklist=vga16fb or nomodeset, either
together or individually on the kernel line resulted in X not starting
and being dropped to a console.
FWIW this is being posted from the LiveCD (USB) during installation
after installing the Broadcom restricted drivers and connecting to a
WiFi network (802.11n WPA2 encrypted).
I´ll let you know how things go after the reboot...
