不使用时如何关闭显示器电源？

我想在 X 时间不活动后关闭 Debian 8 服务器的显示。

我尝试编辑我的/etc/X11/xorg.conf，现在看起来像：

# nvidia-xconfig: X configuration file generated by nvidia-xconfig
# nvidia-xconfig:  version 375.20  (buildmeister@swio-display-x86-rhel47-06)  Tue Nov 1

EndSection

现在它熄灭了，但显示屏仍然打开（因为我有液晶显示屏，背光始终打开）

如何完全关闭显示屏？我正在使用 nvidia 显卡。

要使 X 会话的屏幕消隐，请放入您的.xinitrc或类似的内容：

xset dpms A B C

其中A B C分别是待机、挂起和关闭电源的超时值。我想如果你把它们都做得一样的话，到时候它就会断电。

要使 tty 屏幕消隐，请使用：

setterm -blank 0 -powerdown 0

在那儿。您还可以通过重定向将其发送到特定的 tty；即，追加>>/dev/ttyX.

有关使用 DPMS 的更完整信息请参见此处：
