Thanks Andrew, that was much easier!

greeter_201504260116~ubuntu15.04.1_amd64.deb (89.6 KiB) fixed the
problem for me.

Title:
  gray screen shown when external monitor connected on resume from
  suspend

Status in lightdm-gtk-greeter package in Ubuntu:
  Confirmed

Bug description:
  After resuming from suspend, the Xubuntu login screen is completely
  gray if an external monitor is connected (see step 5 in the procedure
  below).  This problem started occurring after I upgraded to Xubuntu
  15.04; it never occurred under the previous Xubuntu 14.10 version.

  1. Connect external monitor to laptop's HDMI port.

  2. Choose external monitor as the sole display to use (do not use
  laptop's internal display at all: no mirroring or extending).

  3. Suspend the laptop (put it to sleep) by closing the lid.

  4. Wake up the laptop by opening the lid.

  5. The screen is now completely gray on both the external monitor and
  the laptop's internal display.  The mouse pointer is also visible and
  it responds to movements from the laptop's internal touchpad.

  6. Disconnect the external monitor by unplugging the HDMI cable.

  7. The regular login screen now appears.

  8. Reconnect the external monitor by plugging in the HDMI cable.

  9. The screen is now completely gray again, just like in step 5.

  Please fix this gray screen issue!  Thanks for your consideration.
