Suspend without systemd NVIDIA (only suspend)

[KnoyanMitsu]

well i just make script to work suspend with NVIDIA device
because dinit not support script after/before suspend so maybe anyone need this script. (anyway this script ref from nvidia-sleep.sh)

make file on /usr/lib/elogind/system-sleep/nvidia

paste this script

#!/bin/sh

# Special-case suspend-then-hibernate:
#
# If the system was woken by a battery alarm, then systemd will call this script
# to resume from suspend and then enter hibernation. Don't call into the full
# nvidia-sleep.sh script in that case, just write directly to
# /proc/driver/nvidia/suspend.
RUN_DIR="/var/run/nvidia-sleep"
XORG_VT_FILE="${RUN_DIR}"/Xorg.vt_number

PATH="/bin:/usr/bin"

RestoreVT() {
    #
    # Check if Xorg was determined to be running at the time
    # of suspend, and whether its VT was recorded.  If so,
    # attempt to switch back to this VT.
    #
    if [[ -f "${XORG_VT_FILE}" ]]; then
        XORG_PID=$(cat "${XORG_VT_FILE}")
        rm "${XORG_VT_FILE}"
        chvt "${XORG_PID}"
    fi
}

    case $1/$2 in
	pre/*)
        mkdir -p "${RUN_DIR}"
        fgconsole > "${XORG_VT_FILE}"
        chvt 63
        echo suspend > /proc/driver/nvidia/suspend
        ;;

        post/*)
	 echo resume > /proc/driver/nvidia/suspend
         RestoreVT
        ;;
    esac

i hope anyone need it
