我在 Ubuntu 18.04 LTS 中连接外接显示器时遇到问题。Xrandr 可以识别它(HDMI),但只显示光标。我在联想 P73(显卡:英特尔® UHD 显卡 630(Coffeelake 3x8 GT2))中使用 NVIDIA 驱动程序“X.Org X server - Nouveau...”。有人能帮我吗?

/usr/lib/gdm3/gdm-x-session[1700]: (II) No input driver specified, ignoring this device.
奇怪的是,显示器被检测到,我可以看到和移动光标,但背景却是漆黑一片。

我在 Dell precision 7550 上运行 Ubuntu 18.04 时也遇到了类似的问题。
对我有用的是:
关闭安全启动。
跑步 (谢谢 Pablo):
sudo ubuntu-drivers install
重新开始。
答案2
我遇到了同样的问题,但这种方法对我不起作用。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)
。
此选项对我而言已被阻止,因此我不得不卸载我拥有的 nvidia 驱动程序(这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,我能够修复该问题。现在重新安装 nvidea 驱动程序可能也会起作用。
为了找到我安装的 nvidia 驱动程序sudo dpkg -l | grep nvidia
,我刚刚删除了它们sudo dpkg -P {nvidia-driver-xxx}
重启后即可工作
