I used Intrepid(8.10) and my graphics used to work fine with compiz effects and all(on better resolution than 1024x768).Now I have upgraded to Precise(12.04)but I use gnome classic(with compiz effects)as my desktop but the compiz effects seem not to work, only unity 2D works.

When I ran lshw -c video it gives:

*-display UNCLAIMED

glxgears output comes to be around 100fps which used to be around 900fps in Intrepid

You could also try Ubuntu 10.04 LTS. *What are the specs of your hardware? (CPU, RAM, HDD) –  david6 Dec 13 '12 at 7:30
    
Intel® Pentium(R) 4 CPU 2.40GHz with 945G/GZ chipset,1GB of RAM,40GB of HDD Is there nothing that can be done in 12.04? –  peeyush tiwari Dec 13 '12 at 14:55
    
The specs are fine to run either 10.04 LTS or 12.04 LTS. This is simply about a better intel-graphics driver, or if that chipset will support 3D and other effects. Unity (3D) is heavy and uses transparency, scaling, and transform to great affect. You may just need to buy a graphics card. –  david6 Dec 14 '12 at 7:07
