Public bug reported:
This is Xubuntu 18.04.1, kernel 4.15.0-43-generic on a Dell Latitude
5580.
I've found that if I have headphones plugged in when I suspend the
system (either by closing the laptop lid, or by using Whisker menu >
Power button > Suspend), then the system does not resume properly. It
appears that a full boot occurs: Dell logo appears, followed by the Grub
menu, and after selecting the boot option and booting, I get a new login
session instead of my suspended one.
I tried some combinations of booting, suspending and resuming with the
headphones attached or detached. The 'yes'/'no' indicates whether the
headphones were plugged in when I performed the operation. 'ok'
indicates that the resume succeeded: after authenticating to
xscreensaver, my previous session was resumed.
Boot: no Suspend: no Resume: no Result: ok
Boot: no Suspend: no Resume: yes Result: ok
Boot: no Suspend: yes Resume: no Result: fail
Boot: no Suspend: yes Resume: yes Result: fail
Boot: yes Suspend: no Resume: no Result: ok
Boot: yes Suspend: no Resume: yes Result: ok
Boot: yes Suspend: yes Resume: no Result: fail
Boot: yes Suspend: yes Resume: yes Result: fail
(Note: for each case, the suspend was done via Whisker menu > Power
button > Suspend)
The common factor for failure is suspending when the headphones are
plugged in.
