Suspend puts everything into RAM, and shuts off pretty much everything but what's needed to maintain that memory, and detect startup triggers. Hibernate writes everything to your hard drive and completely powers down the system.

What is suspend in Linux?
Suspend mode
Suspend puts the computer to sleep by saving system state in RAM. In this state the computer goes into a low power mode, but the system still requires power to keep the data in RAM. To be clear, Suspend does not turn off your computer.
Is suspend same as sleep?
When you suspend the computer, you send it to sleep. All of your applications and documents remain open, but the screen and other parts of the computer switch off to save power.
How does Linux suspend work?
When a machine goes into the suspend state the kernel freezes (stops) user space programs and kernel threads. Then the kernel will traverse all the devices and calls the suspend methods on each driver. ... It then traverses the drivers and these resume all the devices.
Does suspend mean hibernate?
Suspend does not turn off your computer. It puts the computer and all peripherals on a low power consumption mode. ... Hibernate saves the state of your computer to the hard disk and completely powers off. When resuming, the saved state is restored to RAM.
Is it better to shut down or sleep?
In situations where you just need to quickly take a break, sleep (or hybrid sleep) is your way to go. If you don't feel like saving all your work but you need to go away for a while, hibernation is your best option. Every once in a while it's wise to completely shutdown your computer to keep it fresh.
How do I wake my Linux from sleep?
If you suspend your computer and then press a key or click the mouse, it should wake up and display a screen asking for your password. If this does not happen, try pressing the power button (do not hold it in, just press it once).
What is sleep and hibernate?
Sleep mode stores the documents and files you are operating into the RAM, using a small amount of power in the process. Hibernate mode essentially does the same thing, but saves the information to your hard disk, which allows your computer to be turned off completely and use no energy.
Does suspending save battery?
Some people may opt to use sleep instead of hibernate so their computers will resume faster. While it does use marginally more electricity, it's surely more power efficient than leaving a computer running 24/7. Hibernate is particularly useful to save battery power on laptops that aren't plugged in.

- One thing may worth to try: Switch to console tty1 using Alt Ctrl F1. Login & run sudo pm-suspend. If it does suspend, try resume. ...
- Second way to try, it works for me in XFCE/Mate 16.04 with nvidia proprietary driver. After resume, switch to console tty1 using Alt Ctrl F1. Login.
What is Systemctl suspend?
systemd-suspend reads its configuration from the /etc/systemd/sleep. conf file (or files in a sleep. conf. d directory) and executes hooks from /usr/lib/systemd/system-sleep/ .
What is suspend to disk?
Hibernation (also known as suspend to disk, or Safe Sleep on Macintosh computers) in computing is powering down a computer while retaining its state. When hibernation begins, the computer saves the contents of its random access memory (RAM) to a hard disk or other non-volatile storage.
