    Instruction for Install Ubuntu & sons on PowerMac G5 Quad with Radeon HD

    Ok guys because many people ask me here and there and on youtube and on g+ the same info i make this thread .
    Please read this instruction and do exactly the same thing.

    This guide is for install Lubuntu, Ubuntu Mate 14.04 on Quad G5 with Apple Flashed GPU and RadeonHD (in couple)
    This guide is not for other distro not for debian , gento or opensuse is only for Lubuntu and Mate for the 14.04.2 release
    This is the video of Lubuntu run with RadeonHD performance and speed for your considerations!
    https://www.youtube.com/watch?v=so35SrThHUs (if you like subscribe )

    NOTE: i had been test only the:
    RadeonHD 4650 512mb DDr3 64bit (working)
    RadeonHD 5450 1GB DDr3 64bit (working)
    RadeonHD 6570 2GB DDr3 128bit (working)

    If you success with other cards please report!


    This is the release link of lubuntu :

    http://cdimage.ubuntu.com/lubuntu/re...14.04/release/

    this is the release link for Mate:

    https://ubuntu-mate.org/blog/ubuntu-...rusty-powerpc/


    INSTRUCTIONS :

    Download your prefer distro ... Mate or Lubuntu (PPC )
    Burn the iso at lower Speed on a dvd and from the burner of your powermac G5
    Run it form a cd pressing the "c" on keyboard when turn on your powermac.

    you will have the yaboot screen and at promt write

    Code:
    live video=offb:off video=radeonfb:off video=nouveaufb:off radeon.modeset=1 nouveau.modeset=0
    you will have the video on radeonhd inizialized and see the desktop.

    Make attention dont move the mouse on the border left or on the bottom of the screen because a strange bug on fbdev.

    Click to install ... start the installation ... end.... machine reset

    when the machine turn on again at promt write :

    Code:
    Linux video=offb:off video=radeonfb:off video=nouveaufb:off radeon.modeset=1 nouveau.modeset=0
    When the user credential will exit push fast (without insert the credential) on the keyboard .
    "ctrl+alt+f1" and you will go in tty1

    insert there your users id and password
    and there write

    sudo apt-get install aptitude.

    sudo /etc/init.d/lightdm stop

    sudo aptitude remove xserver-xorg-video-fbdev.

    after....

    sudo nano /etc/yaboot.conf

    where the "append line" add exactly (ADD NOT SWAP or CHANGE ADD):

    Code:
    video=offb:off  radeon.modeset=1 nouveau.modeset=0
    save with ctrl+o and exit

    after...

    sudo ybin -v

    and

    sudo reboot...


    now your machine is full linux ppc funtional!


    For have the 3D right working :

    You need to install the Xeno74 (Christian) Mesa Patch for X1000 but work perfect On Quad G5 and read the readme with instruction inside the
    archive to install it !

    Thankyou Christian for This!

    http://www.xenosoft.de/Xorg_and_unof...e_X1000.tar.gz


    I STRONG SUGGEST to install my optimized kernel 4.00-rc3 for G5 because better performance with radeonhd and much stable compared with
    stock distro kernel


    https://www.dropbox.com/sh/m8c9p3v99...XlqKBFyAa?dl=0


    about video board setup
    Use the Apple PPC flashed in Pcie 16x and the radeonhd on pcie 8x (usually the 3rd from the bottom)
    you need 2 monitors or a monitor who have two video exit because one is for the apple flashed the other is for the radeonhd
    Is not possible have the video on the not flashed video board from beginning because open firmware access to the flashed bios video board

    ISSUES FIX
    For not have problems with the partitioner the best is have a blank hd attached as the primary master sata or ata

    Dont forget to make a 100mb NewWorld partition and the Swap partition the good of swap partition will be half of your Ram eg: 8gb ram 4gb swap, 4gb Ram 2gb swap etc etc


    bye

    Re: Instruction for Install Ubuntu & sons on PowerMac G5 Quad with Radeon HD

    Thanks! I'm a newbie to this, so if I may ask you a follow up question? When is this "When the user credential will exit push fast (without insert the credential) on the keyboard .
    "ctrl+alt+f1" and you will go in tty1". Just after hiting enter at the boot prompt, or after the login picture? I've installet Ubuntu Mate 14.04 on a PowerBook G4, but it freezes when I try to open Firefox or a terminal session. Is there a YouTube video I can watch?

    Cheers, Cato

    On powerbook g4 is different with G5
    You need to put ONLY the line the other instuction is only on G5 with RadeonHD
    Code:
    Linux video=offb:off video=radeonfb:off video=nouveaufb:off radeon.modeset=1 radeon.agpmode=-1

    Thanks Luigi!
    I was looking for a way to make it a permanent setting so that I don't have to write it everytime I reboot. Any leads?
    Also, is it safe to update the Ubuntu install, or will I get packages that break my system?

    Nope cato just edit your yaboot.conf adding where append is with :

    Code:
    "video=offb:off video=radeonfb:off video=nouveaufb:off radeon.modeset=1 radeon.agpmode=-1"
    be sure you dont make wrong nothing there or you will be not more able too boot in linux

    after editing

    do :

    sudo ybin -v

    and reboot

    Thanks again, Luigi!
    One final question, if I may; how do I go about to get my wifi working? I found this command "sudo apt-get install b43-firmware-installer" but it doesn't work. Any ideas?

    Hello Luigi, congrats for the post, great idea.

    I´ve tried with Ubuntu Mate, i can´t start with live parameters, it gets stucked on white scrren. after kernel and ramdisk.
    Then i´ve tried with live (no parameters), it show desktop, then start installation, let me choose language and then mouse pointer gets freeze and then i have to reboot.

    Going to try Lubuntu.
