I installed Ubuntu 11.10 on Mac using rEFIt.
I connected Trackpad and it says that it's a tablet.
If I connect this, this doesn't say that's mouse so it said to type something.
Is there any way to make it work?

The Mac Trackpad is driven by software drivers written especially for the Mac OS, so unless Ubuntu has such a driver, it won't work for you. Applying simple logic before connecting it in the Ubuntu environment owuld have told you this.

You should stick to running Mac OS X on your Mac.

A far better place to post this would be this would be the Ubuntu Forums, as they will be of far more help than anyone here.
