Details:

Problem: Linux Mint Mate 19.1 always wakes up with a grub menu and 30 s wait
time during boot after hibernation, even if you have configured the boot menu
as hidden or with a different wait time.

Others seem to have the same problem:
https://www.linuxmintusers.de/index.php?topic=53547.0
https://www.linuxmintusers.de/index.php?topic=53428.0
https://wiki.hetzner.de/index.php/Grub2_recordfail/en
http://www.ubuntu-forum.de/artikel/53340/grub2-kein-timeout-mehr.html

The Grub Envirementvariable recordfail is not set correctly when switching to
hibernate mode.
This always causes the boot menu to appear because Grub thinks the system was
not started correctly.

Previously, scripts running before and after sleep or hibernate were placed
in
 /etc/pm/sleep.d/ 

Starting with Unbutu 16.04, the directory was changed to
/lib/system/system-sleep/

See 
https://forum.ubuntuusers.de/topic/script-nach-standby-ausfuehren/#post-3392787
or
https://wiki.archlinux.org/index.php/Power_management#Hooks_in_/usr/lib/systemd/system-sleep

The script, which sets the grub recordfail variable, has apparently not been
moved to the new directory.
The script should therefore be copied to the new directory:

sudo cp /etc/pm/sleep.d/10_grub-common /lib/systemd/system-sleep/

with 
sudo vi /lib/system/system-sleep/10_grub-common

you change the script from

#!/bin/sh

# Tell grub that resume was successful

case "$1" in
        thaw)
                [ -s /boot/grub/grubenv ] || rm -f /boot/grub/grubenv
                mkdir -p /boot/grub
                grub-editenv /boot/grub/grubenv unset recordfail
                ;;
esac

to the following

#!/bin/sh

# Tell grub that resume was successful

case $1/$2 in
        post/*)
                [ -s /boot/grub/grubenv ] || rm -f /boot/grub/grubenv
                mkdir -p /boot/grub
                grub-editenv /boot/grub/grubenv unset recordfail
                ;;
esac

because the transfer parameters have changed.

My system boot now works under Linux Mint Mate 19.1 on several computers
without 30s waiting time in the grub menu after a hibernate state.

Maybe someone of the Grub developers can take a closer look at this problem.
