I recently got an old iMac G3 and felt the need to replace the crappy existing MacOS 9 system with my favorite system : Linux of course!

After a mandatory RAM upgrade (from stock 64M to 512M), I found that the CD drive is extremely picky/worn-out and wouldn’t boot any burned install CDs…

But that’s not enough to stop me, since those iMac models support booting from the network.

I first tried to netboot Debian Squeeze on it, but there were some issues (yaboot started but couldn’t load the kernel).

After some research, it appears that Ubuntu has an updated netinstall iso which just works!

imac xorg.conf PPC All versions
There is alot of confusion over The graphical display settings on older PPC imac computers.

Here I've tried to put together xorg.conf file s that people claim to work for the differing imac versions. Ymmv. Feed back welcome if you have an imac running GNU/Linux please post it along with your machine model.
