I am using an Acer laptop with ATI Mobility Radeon HD 4570 graphics card. But when I boot from a Knoppix 6.2.0 linux live CD, the compiz fusion does not work nor does the other visual effects (like CUBE effect, etc) work. When I used the CD on my desktop with very modest hardware , the effects worked fine.
Can any one suggest me solutions for this ? Do I need to type down any cheat code specific for my graphics card ? Please help !!!
