Introduction
deprecated, should be overworked as wlan is working, 3d is working etc
This wiki will describe the installation process of Gentoo Linux on an Apple Powerbook G4 15" SuperDrive. Updates as soon as I completely nail down everything with my personal configuration. Some of the main issues include sound and suspend-to-RAM/sleep capability, which I hope to address as soon as possible. For now I can provide a thorough description of the actual hardware, kernel modules/chipset support needed (and those not needed).
This wiki is aimed at pretty much everyone. New Gentoo users will (hopefully) find it an extremely informative document, while seasoned veterans may just be here looking for that one evasive setting they forgot. Either or, enjoy. =)
For the most part, follow the PPC Handbook to a 'T'. I'll try and highlight any quirks during the install, but this wiki mainly deals with post-configuration and kernel/module/keymapping issues.
Also, trying to consolidate the extremely good forum posts and howtos already out there and apply them to this specific machine.
Installation Environment
AFAIK, configuration varies on Powerbooks, iBooks, and older machines. This wiki is designed specifically for the Aluminum PowerBook 15" G4 5.4 (the new series is 5,6 i believe). However that does not mean that this information is not pertinent to your machine, and it may work. All I can guarantee is that it works on the 15" AlBook. :)
System Info
This is just a handy reference. =)
Some (commented) output commands on this specific machine so we're all on the same page:

Kernel Configuration
Here I'll discuss some of the kernel options available to a PPC user, moreover which ones apply specifically to this machine.
Keep in mind, this is for an out-of-the-box, fresh-smelling PowerBook. Make exceptions for the obvious, e.g. you use SCSI hardware or I20.
- You need to have both options selected in Code Maturity Level before you do anything else.
- You do not need any of the top-level options below File Systems, these are all user choices and as such...it's your choice =)
- The General Setup options are just that, general. They should be configured however you like, if in doubt, read the Help.
- You need to enable kernel module support, and autoload at your discretion however this is desirable in every situation I've encountered.
The only options listed are the ones that I have selected, so they will appear out of order in make menuconfig.
To the nitty-gritty:
Processor
| Linux Kernel Configuration: Processor Opts |
Processor Type: (X) 6xx/7xx/74xx/52xx/8260 [*] AltiVec Support [*] Thermal Management Support |
Platform Options
| Linux Kernel Configuration: Platform Opts |
Machine Type: (X) CHRP/PowerMac/PReP [*] Support for Open Firmware device tree in /proc [*] Support for PReP Residual Data [*] Support for reading of PReP Residual Data in /proc |
Device Drivers
NOTE: This applies mostly to any special hardware you might be using, so be sure to DOUBLE CHECK before you change things around in this section! There are some things you most likely will not need listed below that are pretty obvious, but again, use your common sense.
- Not needed:
- MTD support
- Plug and Play support
- ISDN support
- Fusion MPT support
- I20 support
- Parallel Port support
- SCSI support
- RAID and LVM support

- Misc devices
- MMC/SD Card support
- Infiniband support

File Systems
- You should know which filesystems you need, but this is a good start:
- Local Filesystems
- ext2
- ext3
- reiserfs (nice to have on a separate /var or /usr partition, for portage/rsync)
- HFS/HFS+
- Network Filesystems
- SMB/CIFS (windows shares)
- NFS v3/v4 (Unix shares)
- Local Filesystems
- And of course, don't forget to add support for the Apple Partition Map in Advanced Partition Selection.
Other brief notes
Sleep/Suspend
- As of now, the 2.6.11-r6 sources include support for sleep (finally).
- You should have all the related power options compiled into the kernel.
- You should perform the following:
emerge --sync emerge -u gentoo-sources cd /usr/src; rm linux; ln -s /usr/src/linux-2.6.11-r6 linux cd linux; make menuconfig make all
- edit /etc/yaboot.conf as necessary
- install app-laptop/pmud and app-laptop/pbbuttonsd
emerge pmud emerge pbbuttonsd rc-update add pmud default rc-update add pbbuttonsd default
At this point you should be able to initiate suspend-to-RAM with the snooze command.
Open Firmware
- This is just in case you screw up the device= line in your yaboot.conf and don't want to reboot to the livecd to fix it. This is of course assuming you have a kernel that will boot, and references the yaboot.conf used above.
printenv /* this will give you a nice little printout of your settings. */ setenv boot-device hd:2 /* this will reset your boot device to hd:2 (your bootstrap partition) */ boot hd:2,\\/boot/your.kernel.here /* and hopefully all goes well */
To reset your settings:
reset-all

Unresolved Issues
- I personally have a number of unresolved issues with my system as of right now:
- The system will not save the date when shutting down.
- yaboot will only load into the firmware after a system halt, not a soft reboot.
- i get no response from showkey on Fn+F6 -- Fn+F10. My keycode for Fn+F5 is 225 and this is also where my /usr/include/linux/input.h stops listing keycodes.
Mathias Grimm has developed an app called pbbuttonsd[1] to handle these special keys!
I know yours it is not a PowerBook but you can still try! It's working perfectly on my mac!
He's also developing a graphical interface (GTk based)

Initially created from trial/error and a lot of resources on the net by [[[User:Sam|Sam]]]. A big thanks goes out to Theefer @ The Gentoo PPC Forum: Theefer
And of course, the Gentoo Foundation and the Gentoo Development Team for making such a wonderful system possible.
