我在 Acer Aspire VN7-592G 上安装了 18.04 LTS Ubuntu。这台笔记本电脑配备了 Nvidia 独立显卡 GTX960M。在下面,您将找到 lspci 结果(grepping 3D 和 VGA):
01:00.0 3D controller: NVIDIA Corporation GM107M [GeForce GTX 960M] (rev a2)
00:02.0 VGA compatible controller: Intel Corporation HD Graphics 530 (rev 06)
至于驱动程序,我安装了在 Ubuntu repo 上找到的 Nvidia 390.116 驱动程序。现在,我的问题是:我看不到连接到 HDMI 端口的任何外部显示器。
xrandr命令的结果如下:

在之前的安装中,我尝试切换到 lightdm、Wayland、将“addmode”添加到 xrandr 并手动激活该模式(如https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1771185)。什么都没起作用。
有什么建议吗?
谢谢你!

喝了一杯冰啤酒并读了这篇文章后,我似乎找到了解决方案:
https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1771185/comments/26
安装删除了我的 xserver-xorg 输入。因此,在安装了上一个链接中建议的软件包后,我发出了以下命令:
sudo apt install xserver-xorg-input-all
现在它起作用了!!
