hi

im sure this is a simple solution but i just cant find it

the compiz effects are not working on my Ubuntu which is installed on my new iMac.

that doesnt make sense i thought mac would have a appropriate hardware for something like compiz... but it doesnt work... im a long time ubuntu user and sure i installed it fine.

does any one know what the problem might be?

please ask if you need any more information

Thanks in advanced
