Title:
  Unity is sluggish and uses a lot of CPU (even with hardware support)
  on low-end systems

Status in Unity:
  Fix Released
Status in unity package in Ubuntu:
  Fix Released

Bug description:
  I asked this question already on Askubuntu, but was directed to file a
  bug: I have a nice Lenovo Thinkpad Edge 11 AMD Neo II with a ATI
  Radeon 4225 integrated graphics device. In my perception this is
  already a not-so-lowspeced device, but still a netbook.

  Up to Ubuntu 12.04 precise pangolin I preferred Unity2D over Unity
  mainly because it did perform much better than Unity and moreover I
  was able to achieve 5-6h with one battery charge. The typical load of
  an idling desktop settled around 0.00 to 0.02.

  Yesterday I tried the new Beta 2 of Ubuntu Quantal Quetzal: This does
  no longer offer a Unity2D version. The performance itself has
  definitely improved over Unity in precise, but nevertheless I do
  experience now a minimum load of 0.24 to 0.36 while completely idling.
  According to top this is mainly due to compiz eating about 3-6% CPU
  all the time.

  In comparison to my Unity2D experience, quantal is more sluggish, eats
  much faster my battery and produces significant more fan noise. I
  already tried a few tweaks like static blurring, fast texture renderer
  or choosing alternate window manager on precise, but without a
  significant change.

  Are there ways which enable me to continue to use Ubuntu/Unity on my device without major loss of functionality, performance and battery life?
