Suspend menu option vanishes in Linux Mint

This has happened a few times for me so I am documenting it for next time and for other people with the same issue.
Run the following command in a terminal.
bash
gsettings reset-recursively org.cinnamon.settings-daemon.plugins.power
Yes there are many other things to try but this works reliably for me with no need to reboot.
Note: It will take a few minutes to display. I was closing all apps to reboot after modifying Grub but found the option in place.
FYI.
Here are the fixes for Grub iof needed.
bash
sudo xed /etc/default/grub
Find the line GRUB_CMDLINE_LINUX_DEFAULT.
Change it to add one of these common ACPI fixes:
bash
# Try this one first
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_sleep=nonvs"
# Other options to try if the first fails:
# GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=force"
# GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pci=noacpi" # More drastic Save the file (Ctrl+O, Enter, Ctrl+X), then update GRUB and reboot:
bash
sudo update-grub
sudo reboot

Wobbly windows !

One of the things I like to do is have 'wobbly windows' in my Linux Mint install.
Why? I thinks it's kind of cool and Windows and Apple can't do it which makes it even cooler.

Open Extensions:
Press the Super key (Windows key) and type "Extensions", then open the application.
Find Extension:
Click the "Download" button or search for "Compiz windows effect" (or "Wobbly windows").
Install:
Click the plus (+) icon next to the extension to install it.
Enable:
Go back to the "Manage" tab, find the extension, and toggle it on.
Apply Fix (Optional but Recommended):
For smoother redraws, open a terminal and run in a bash terminal:
echo "CLUTTER_PAINT=continuous-redraw" | sudo tee -a /etc/environment && sudo reboot
Test:
Drag a window around to see the wobble.
