Public bug reported:

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)

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!
