Can not enable Compiz effects / Desktop effects for Intel based motherboards:

Due to some performance problems Intel motherboard chipsets were blacklisted in Compiz. If you were using earlier releases of Ubuntu and could enable the shiny Desktop effects and also using the Intel based motherboard then most probably the reason you can`t enable them any longer maybe this. The workaround is to add a corresponding line in compiz-managers settings to skip the check of chipset. To do this efficiently type in terminal,

mkdir -p ~/.config/compiz/ ; echo SKIP_CHECKS=yes >> ~/.config/compiz/compiz-manager

You need to restart the machine afterwards.
