EXAMPLES

$ # Simple suspend
sudo pm-suspend

# With video quirks
sudo pm-suspend --quirk-vbe-post

# Suspend with all auto quirks
sudo pm-suspend --auto-quirks

# Hibernate instead (suspend to disk)
sudo pm-hibernate

HOOKS

Custom scripts in /etc/pm/sleep.d/ run before suspend and after resume:

$ #!/bin/bash
case "$1" in
    suspend|hibernate)
        # Before sleep
        ;;
    resume|thaw)
        # After wake
        ;;
esac

CAVEATS

Deprecated on systemd systems (use systemctl suspend). Requires working ACPI. May need quirks for some hardware.

HISTORY

pm-utils was developed by Peter Jones and the Fedora team for Linux power management before systemd.
