Hi all,

Not sure if this is the proper list for this.

Attached is my attempt at getting iMac G3's working with as few steps
and typing as possible. If anyone thinks it wiki worthy, please feel
free. I know some of it is in the PPC FAQ already.

Also, X86 users with old cards hit by the removal of XAA
(Rage,SIS,Trident,etc.) may find this workaround easier than removing
the driver and falling back to Vesa.
Create simple /etc/X11/xorg.conf

BTW, my current "lowest spec success" running Lubuntu 13.04:
1999 iMac G3 333 with a whopping 160 Meg of Ram.
Needless to say it is slow with that little ram, but it runs and can
browse the web. :)

Regards,
Str8

This applies to iMac G3 with Rage 128 video. (All Slot-Loading iMac G3's)
*Ubuntu 13.04 Raring Ringtail but should work with 12.10 as well.



1. To boot the live desktop iso:
boot: live video=offb:off video=aty128fb:1024x768@75

The splash screen will display and then the screen will go blank.

2. Press <ctl><alt><F1> to get to a command prompt.
3. sudo nano /etc/X11/xorg.conf
4. Enter the following lines. *If you can't see the cursor off to the left,
just tab key until you can see it.

5. <ctl> o and enter to save
6. <ctl> x to exit back to prompt
7. sudo stop lightdm
8. sudo start lightdm

If unsuccessful, <ctl><alt<F1> to go back to prompt and check steps 3 and 4
for type errors.

This applies to iMac G3 with Rage or Rage Pro video. (All Tray-Loading iMac G3's)
*Ubuntu 13.04 Raring Ringtail but should work with 12.10 as well.



1. After performing netboot/mini or altnerate install:
boot: linux snd-powermac.blacklist=yes 

Allow SEVERAL minutes for the machine to finish booting.
The screen will be blank or have some garbled messages.

2. Press <ctl><alt><F1> to get to a command prompt.
3. sudo nano /etc/X11/xorg.conf
4. Enter the following lines. *If you can't see the cursor off to the left,
just tab key until you can see it.

The "NoAccel" option is necessary since XAA was dropped > 12.10 and this card
does not fall back to shadowfb on it's own properly.
Blacklisting snd-powermac isn't necessary to boot, but a LOUD shrill will be
hear instead of sound if any sound is played without this.
