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.
