Title:
  Compiz freezes when screen is disconnected

Status in compiz package in Ubuntu:
  New

Bug description:
  I have an laptop with Intel HD4000 graphics running compiz (with mint
  mate).

  When I disconnect external screen the main laptop screen blinks and
  starts displaying old stuff on left half and old stuff from
  disconnected screen on right half. And it freezes in this state
  although mouse is still moving - but I cannot click anything.

  Do dmesg messages, but xsession-errors contains this:

  failed to create drawable
  compiz (core) - Warn: glXCreatePixmap failed
  compiz (opengl) - Error: FBO is incomplete: GL::FRAMEBUFFER_INCOMPLETE_ATTACHMENT (0x8cd6)

  compiz (opengl) - Error: FBO is incomplete: GL::FRAMEBUFFER_INCOMPLETE_ATTACHMENT (0x8cd6)

  This happens with both Trusty stock x server and oibaf xserver, but
  this doesn't happen if I disable compiz. Also, problem exists when I
  connect screen, i.e. any change in screen config triggers this issue.

  Please let me know if I can provide any useful information to help
  fixing this issue.

  Thanks!
