禁止屏幕在播放视频时自动关闭

目录

貌似Lose系统下看在线视频的时候不会超时自动关闭屏幕,但是我在Arch下就一直晃鼠标、按键盘来著,这严重违反了DRY原则。于是昨天终于写了这个脚本,当全屏播放视频的时候,关闭屏保和显示器的节能特性,否则则激活它们。由于是在X的级别实现,理论上应当适合所有桌面环境。

```bash #!/bin/bash # Baby-sitter of the monitor's DPMS idle_period=60 ss_switch_off=0 ss_is_off=0 while true; do # Read DPMS state xset -q|grep "DPMS is Disabled" > /dev/null && ss_is_off=1 || ss_is_off=0 # Get pid of the current window active_window_id=`xprop -root | grep "_NET_ACTIVE_WINDOW(WINDOW)" | cut -d" " -f5` decimal_id=`xprop -id $active_window_id | grep PID | cut -d" " -f3` # Traverse all libflashplayer.so for pid in `ps -ef|grep -v grep|grep libflashplayer.so|awk '{print $2}'`; do # If the current window is libflashplayer.so if [ "$pid" -eq "$decimal_id" ]; then ss_switch_off=1 break else ss_switch_off=0 fi done if [ $ss_switch_off -eq 1 ]; then # Turn off DPMS echo Turn off DPMS if [ $ss_is_off -eq 0 ]; then echo Action xset s off xset -dpms fi else # Turn on DPMS echo Turn on DPMS if [ $ss_is_off -eq 1 ]; then echo Action xset +dpms xset s on fi fi sleep $idle_period done ```

似乎对非全屏播放的情况没有什么好方法。
