Hello !
Rotate Cube, and all visual effects was working perfectly on my desktop without any extra configuration, but none of them are working on Dell Inspiron N4050 i5

I tried Ubuntu 10.10, 12.04 LTS 64-bit .. same,Visual effects was one of the most important factors which encourage me to migrate to Linux system "Ubuntu" .. today am really disappointed.

Note: I tried to discuss that on "Feedback on the Dell Inspiron N4050" https://answers.launchpad.net/ubuntu-certification/+question/209683

But no luck !!

Is there is any way I can make those features work on my laptop or it's hardware limitation?! and if it is hardware limitation why no one mention that on this link ?
