I recently installed Ubuntu 14.04 Desktop on a virtual machine with 1.5 GB of RAM and 20GB hard-drive. The graphics card I have is "Intel Graphics HD 3000".

Some posts suggested to install the graphics driver 

intel-linux-graphics-installer_1.0.4-0intel1_amd64.deb

I did that but still compiz is taking lot of CPU and the machine is very slow. Please suggest a remedy. I was pretty comfortable with 12.04 LTS and if it's some known issue with 14.04, I'll revert to 12.04 LTS.

Thanks,
