[Bug 1361644] [NEW] 14.04. Resume from suspend with HDMI display, login/lock screen freezes.

 

Public bug reported:

Hello friends. I have a Dell Latitude E7440 that came with Ubuntu on it.
I am running 14.04.1 with all available updates as of today. I noticed
if my laptop is in suspend mode and I plug in an HDMI monitor, then open
the lid to resume, it freezes. The lock screen allows me to move my
cursor around, but I cannot click anything, and the keyboard itself does
not respond whatsoever.

If I do these steps in any sort of different order, as in resume laptop
first then plug in, etc., it's fine. It's just when the system is
resuming with a new HDMI source plugged in that wasn't there when it
went to sleep.

Thank you for your time, dedication, and hard work!
