Ah, right. In that case, don't worry. I am cursed to have an iPhone, too. :¬(

Er, well, OK, you can if you want, but I don't think that a 2010 OS is
going to cope well with a newer iMac.

OK. So far so good. That's also what I'd try with 12.04, basically.

If it doesn't work, you can also start X using its "bulletproof"
failsafe mode. Instructions here:
https://wiki.ubuntu.com/BulletProofX

This is getting the GUI to start in VESA mode, with no driver at all
installed. I have used this method successfully to get Ubuntu 11.04
working on a machine with an AMD Fusion APU, which was not
well-supported at all on Linux at that time.

You can also switch to a text console using Ctrl-Alt-F1 if the GUI is
not visible and install stuff from the command line - Google should
provide more details. I am not sure if the Catalyst drivers can be
installed this way, though.

However, the main point is that if you are using the Alternate CD (and
*not* the server CD) then you don't need to install the desktop, nor
build-essen. They should already be there.

Another option might be to try to install the server version, update
it /first/ and /then/ install ubuntu-desktop.

Sounds like a graphics driver issue to me, but I can't say for sure; I
don't own an Intel Mac and have never run Linux on my Macs except in
order to install Morphos. TBH with an OS as pleasing as Mac OS X, I've
never felt any need for Linux.

Well, TBH, Ubuntu probably isn't the best OS for a Mac and a Mac isn't
the best machine to run Ubuntu.

Also, it might be worth seeing if you can borrow an external monitor
for a short time, just to get it installed and working.

But you shouldn't need the dev tools or to compile anything just to
get the desktop installed. Possibly to build bits of Catalyst but I
don't remember seeing that... Can anyone comment on this?

Well I just installed 10.04 with decent success (this link is exactly what I did within the last 6 hours https://bugs.launchpad.net/ubuntu/+source/linux/+bug/542660/comments/109)

Main reason for a Linux move is simplly because my industry (Visual Effect for Film) is moving toward linux and so I am exploring the possibilities plus the programs we (I) mostly use were developed and built on linux systems for linux so they tend to be more stable plus I dont care for the way apple and windows are going with there OS. They are both beautiful but they are just screwing themselves over on the framework. As for the monitor if I can find one I will use it but really my ideal goal. But do you have a preference for a stable linux OS on mac? 

Thanks for the help!
