Ubuntu 16.04 LTS 从挂起状态唤醒后无法检测到外接显示器

我已经在 Razer black stealth 上安装了 ubuntu 16.04 lts。当我暂停会话并重新登录时,除非我重新启动,否则无法检测到外接显示器。以前有人遇到过这个问题吗?

w-oush 的输出:

adi      tty7     :0               12:17m /sbin/upstart --user  

显示器已连接到 HDMI,我正在显示器上输入此内容。不知道为什么 xrandr 显示它已断开连接。

答案1

列出显示:

xrandr——查询(或 w-oush)

1. 禁用您想要的显示器 (:0) 的 dpms 功能。

 xset -display :0 -dpms

2. 如果此方法无效,请尝试以下操作:

 setterm -powerdown 0
