如何编写 bash 脚本来为不同的 Ubuntu 桌面设置锁屏超时？

Question

我正在使用 Ubuntu 18.04，并且已经为 gnome 环境编写了脚本。我需要知道我们能否为所有 Linux 桌面环境使用通用脚本？

下面是我的脚本，

#!/bin/bash

# This script has been tested in the Ubuntu 18.04.

MAXIMUM_IDLE_DELAY=300        # maximum session idle valuse for the power management in seconds
MAXIMUM_SCRN_LOCK_DELAY=300   # maximum screen-saver lock delay in seconds
MAXIMUM_DELAY=$(($MAXIMUM_IDLE_DELAY + $MAXIMUM_SCRN_LOCK_DELAY))

IS_ENABLED=$(gsettings get org.gnome.desktop.screensaver lock-enabled)
USER_IDLE_DELAY=$(gsettings get org.gnome.desktop.session idle-delay | cut -d ' ' -f2)
USER_SCRN_LOCK_DELAY=$(gsettings get org.gnome.desktop.screensaver lock-delay | cut -d ' ' -f2)
USER_TOTAL_DELAY=$(($(gsettings get org.gnome.desktop.session idle-delay | cut -d ' ' -f2) + $(gsettings get org.gnome.desktop.screensaver lock-delay | cut -d ' ' -f2)))

function screen_lock_Test(){
    if [ "$IS_ENABLED" == "true" ] && [ "$USER_IDLE_DELAY" -gt 0 ];then
        if [[ $USER_TOTAL_DELAY -le $MAXIMUM_DELAY ]];then
            echo "Configurations matching with the given settings" 1>&2
            return 0
        else
            echo "Screen lock settings takes too much time to lock down !!!!!" 1>&2
            return 1
        fi
    else
        echo "Screen lock configurations do not match with the given settings !!!!!" 1>&2
        return 1
    fi
}

screen_lock_Test
echo $?
