[Bug 1543613] Re: After Xenial upgrade display will no longer turn on when waking from suspend.
apport information
** Tags added: apport-collected
** Description changed:
I was unsure what daemon actually controls suspending of a laptop when
the lid is closed, so filed under "I don't know.". After a fresh and
patched install of Xenial, when I open the lid to my laptop it will wake
up from suspend, however the LCD does not turn on, as far as I can tell
everything is actually working underneath but I need to do a hard
restart to make the machine usable again. My laptop is a Dell Latitude
E6440. I will gladly provide any info needed.
