Public bug reported:

Doing cert testing on a Vostro 3750.  The Intel graphics card is
currently in use.  When I plug an external monitor into the VGA port on
this machine, the system sits for many seconds before compiz crashes and
then the external monitor shows the extended desktop.

When connecting an external monitor to the HDMI output, however, the
monitor power light changes color, indicating that it's getting some
sort of signal (and the "No Signal" message box goes away) but no
desktop ever appears on the external display.
