apport information ** Tags added: apport-collected compiz-0.9 regression reproducible trusty ubuntu
** Description changed: I have two Dell U2711 monitors plugged into a HD7750 card. One monitor is connector via DisplayPort, the other via DVI. If I switch the monitors off then on again the monitor connected via DisplayPort displays a blank screen. The DVI monitor works correctly. I have to reboot the machine to get the DisplayPort monitor working again. This problem did not occur with 13.04.
