Public bug reported:
Before today's update, I could use an exernal monitor plugged into the
mini display port (intel card) of my Inspiron xps 15z. Now after
today's update the display preferences applet doesn't detect the
external monitor and clicking on Detect Displays doesn't help. I tried
rebooting on the previous (3.0.0-15) kernel version and the problem
remained so I think its due to a compiz update.
Here is the list of updated packages from /var/log/apt/history.log:
