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
