SUMMARY
System becomes unresponsive (hard restart required) after disconnecting the
third display (via hdmi switch). Coredump created on this occasion.
STEPS TO REPRODUCE
1. Disconnect third display (via hdmi switch - probably irrelevant)
2. Remaining two displays (connected via DVI) should refresh and show the
reconfigured desktop - but they remain black - and no keyboard response can
bring the system back.

System hang and coredump created.
EXPECTED RESULT
System remains functional on a two display setup.
