I came a bit closer to getting Lubuntu 16.04 running on the 3,1 MacBook Pro

Thanks Fritz Hudnut for pointing me in the right directions in the Mac maze.

I erased and re-installed the Macintosh HD with Snowleopard. And after installing rEFIt and this time rEFIt recognises the Lubuntu install, and GRUB, also loads. However GRUB appears to need some tweaking.

The situation is this:

When I boot the Lubuntu LiveUSB then i need to add nomodeset to the grub command. Then the LiveUSB boots to the desktop.

But the GRUB that tries to boot Lubuntu looks like this:

=====================================================

menuentry 'Ubuntu' --class ubuntu --class gnu-linux --class gnu --class os $menuentry_id_option 'gnulinux-simple-907d721b-5385-4af0-b565-29220ac4a6d7' {
    recordfail
    load_video
    gfxmode $linux_gfx_mode
    insmod gzio
    if [ x$grub_platform = xxen ]; then insmod xzio; insmod lzopio; fi
    insmod part_gpt
    insmod ext2
    set root='hd0,gpt6'
    if [ x$feature_platform_search_hint = xy ]; then
search --no-floppy --fs-uuid --set=root --hint-bios=hd0,gpt6 --hint-efi=hd0,gpt6 --hint-baremetal=ahci0,gpt6 907d721b-5385-4af0-b565-29220ac4a6d7
    else
search --no-floppy --fs-uuid --set=root 907d721b-5385-4af0-b565-29220ac4a6d7
    fi
linux /boot/vmlinuz-4.4.0-36-generic.efi.signed root=UUID=907d721b-5385-4af0-b565-29220ac4a6d7 ro quiet splash $vt_handoff
    initrd    /boot/initrd.img-4.4.0-36-generic
}


================================================



What do I need to look at to make this work.

I suspect that it is the NVidia Radeon that needs the correct instructions.

but i also see insmod ext2
What is that about? my Lubuntu is in a ext4 partition


I also compared with the Grub.cfg that Fritz has on his slightly newer MacBook but that has different graphics hardware so i then still don't know what to configure.

Also Grub tells me not to edit the file and to use grub-mkconfig. how does that work?

How do i know what parameters need to be configured for the Radeon GFX?


I experimented a bit with GRUB by using the 'e' option to edit the boot parameters but didn't yet accomplish a succesful boot.

What can i try?






And another very annoying thing is Apple single button touchpad, not having a right button in Lubuntu that's quiet a challenge
