Title:
  Bad user experience on virtual machines

Status in Unity:
  Confirmed
Status in “unity” package in Ubuntu:
  Confirmed

Bug description:
  There are currently (at least) two design/technical decisions which have a quite bad impact on running Ubuntu desktop in a virtual machine:
  1) Dropping unity2d in favour of unity+llvmpipe. Since there is no way (at least none that is easy to find) to disable playful effects this puts a considerable stress on the emulated cpu(s). On my desktop, which may not be state of the art but used to be usable for running unity2d desktops in VMs, doing even simple tasks is painfully slow. For example it takes about 3s(!) from when a window begins to fade in until it can be used. And the same when minimizing. On that machine I also see a lot of X crashes which might be related to overwhelming the cpus (bug 1056080) since a faster machine does not seem to suffer that badly.
  2) Adding the Amazon search to the dash search (again without any reasonably easy way to disable this). This further puts stress on the cpu(s) and on the same desktop every keypress is delayed about one second (at least). It also adds to network usage (not to mention any privacy or potential parental control issues).

  Those together currently make my experience rather bad. To get
  anything done within the desktop vm I seem to drag my feet through a
  pool of mud. And that is just one VM running. Anybody hosting virtual
  desktops will rip out lots of hair and likely leave for at least the
  ubuntu-gnome-desktop (classic unaccelerated) which would be rather sad
  and completely unhelpful in those cases where the ubuntu desktop was
  used in a VM for testing.

  I can understand that getting rid of a duplicated desktop framework
  will help to focus on the main unity project. But I think in that case
  there really should be options that allow to reduce the graphical
  overhead and the amount of feature overhead in a more user-friendly
  way.
