Comment 56 for bug 542660

I could not use Unity although the ATI Drivers were installed. I had to switch to the classic desktop session. Natty's classic desktop is still very buggy so I'm now using Maverick.

I'm having a lot of problems to make my iMac working smoothly with Ubuntu. I'm reporting each issue on launchpad and the apple user forum.

Here are the threads I've opened:

I'm still fighting with the mouse and keyboard issues.

The only difference I could appreciate with Natty was that the internal speakers were almost working without any trick, see:

Hope it helps.
