Another problem, bug report here:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1458327

When using Marco, I can connect to an external monitor, as one would
expect. However, using Compiz, both screens go black on connection.

So, can have either working suspend, but no external monitor with
Compiz, or a working external  monitor, but no suspend with Marco :-(

Title:
  Ubuntu Mate with Window Manager Marco fails to properly resume from
  Suspend on DELL XPS13

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  I have the DELL XPS13 laptop which came factory pre-installed with
  Ubuntu 14.04. I changed the desktop to Ubuntu Mate. This had the
  Window Manager "Marco (Simple desktop effects)" activated.

  Whenever I went into Suspend, the laptop did resume, but the desktop
  was not redrawn, no panels, no menus and submenus, no buttons. When I
  moved the mouse pointer over the places where I assumed the elements
  to be, some of them did show up, and were clickable. After a reboot,
  all was normal.

  WORKAROUND: System > Control Center > MATE Tweak > Windows > Window
  Manager from Marco to Compiz.
