Ubuntu 16.04 外接显示器停止工作(黑色)

Ubuntu 16.04 外接显示器停止工作(黑色)

我已经在笔记本电脑上运行 Ubuntu 好几年了,几个月前升级到 16.04,没有出现任何问题。我经常外出,因此经常通过 HDMI 将笔记本电脑插入外部屏幕,并使用 VGA 适配器连接投影仪。

直到昨天,我从未遇到过第二个屏幕的问题。当我插入显示器时,无论是直接插入(HDMI)还是通过 VGA 适配器适配器插入,Ubuntu 都能识别它,但什么也不显示。

我的显示器显示 2 个屏幕"Build in display""Goldstar company 23"就像往常一样,我尝试切换主屏幕、辅屏幕和镜像屏幕,但无济于事。我还尝试过在插入电源、未插入电源的情况下启动它,使用不同的显示器、不同的电缆,检查 BIOS 中是否有某些东西被禁用,并尝试按下各种显示器按钮在外部镜像开关之间切换等。

我甚至刚刚重新安装了 Ubuntu 16.04,以查看后台是否出现了问题,但结果还是一样。

感谢您的帮助!

答案1

我知道这已经过去很久了,所以感谢所有试图提供帮助的人。原来是 HDMI 插座的硬件问题。与 Ubuntu 无关!

答案2

我的电脑也出现了同样的问题,只不过外部显示器只有在我登录后才会自动关闭(提示没有输入)。在此之前,显示器显示正常。如果我打开显示器设置来解决问题,我可以让笔记本电脑检测屏幕并对其进行配置。但是,按下“应用”后,两个屏幕都变黑,并且在 30 秒的“保留此配置?”对话框后无法恢复设置。第二次登录时,问题就显现出来了。我 2 天前更新了 Ubuntu

我在华硕 N56V 上运行 Ubuntu 16.04 LTS。

编辑 我刚刚通过将图形驱动程序切换为“使用 X.Org X Server...” 来修复此问题。

答案3

使用“Ubuntu 的高级选项”启动并选择另一个内核(旧内核)。
