Suspend

Last updated:

Reference:bbs.archlinux.org

Usage

shell

systemctl COMMAND

Command	Description
`suspend`	Also known as sleep, saves the current state to RAM and suspends the system.
`hibernate`	Saves the current state to disk and shuts down the system.
`hybrid-sleep`	Saves the current state to both RAM and disk, then suspends the system.

In some machines ethernet may become unusable after hibernation. Restarting the ethernet module seems to fix it.

Find the name of the module:

shell

lspci -knn

Create the file /usr/lib/systemd/system-sleep/fix_ethernet.sh:

shell

##!/bin/sh
case $1/$2 in
  pre/*)
    ;;
  post/*)
    modprobe -r alx
    modprobe alx
    ;;
