HDMI-1-1 disconnected (normal left inverted right x axis y axis)
我的主要关注点是最后一行:
HDMI-1-1已断开连接
。我已经插上了一台准备好使用的显示器,但无论我做什么都无法检测到它。我有一张Nvidia显卡,在更新之前我使用的是专有驱动程序。当外部显示问题首次出现时,我最初尝试切换回开源的Xorg驱动程序。然而,在重新启动后,Ubuntu显示我的驱动程序设置为"手动安装的驱动程序",并且不允许我更改它: 有什么推荐吗?
sudo apt-get install laptop-mode-tools && sudo lmt-config-gui
并启用video-out
可能会有所帮助。 - Anton3
