我在 Ubuntu 18.04 LTS 中连接外部显示器时遇到问题。Xrandr 可以识别它(HDMI),但只显示光标。我在 Lenovo P73(显卡:Intel\xc2\xae UHD Graphics 630 (Coffeelake 3x8 GT2))中使用 NVIDIA 驱动程序“X.Org X server - Nouveau...”。谁能帮我?

我在 Dell Precision 7550 上使用 Ubuntu 18.04 时遇到了类似的问题。
对我有用的是:
关闭安全启动。
运行(感谢巴勃罗):
sudo ubuntu-drivers install
Run Code Online (Sandbox Code Playgroud)
重新开始。

我遇到了同样的问题,但这对我不起作用。解决方案是卸载所有 nvidia 驱动程序并使用适用于我的 GPU 的开源驱动程序。转到Software & Updates-> Additional Drivers--> Using X.Org X Server (open source)。
这个选项对我来说被阻止了,所以我不得不卸载我拥有的 nvidia 驱动程序(可能是问题的根本原因)。卸载我的 nvidea 驱动程序并选择开源驱动程序后,我能够解决该问题。也许重新安装 nvidea 驱动程序现在也可以工作。
为了找到我使用的已安装的 nvidia 驱动程序sudo dpkg -l | grep nvidia
,然后将其删除sudo dpkg -P {nvidia-driver-xxx}
重启后有效
