我安装了 Deepin 20（社区），但 HDMI 端口无法正常工作。
我已经检查过 ISO MD5，一切正常。另外，我尝试在以下操作系统中安装，结果是：
- Deepin 15.10：HDMI 不工作，未检测到 NVIDIA
- Deepin 15.11：HDMI 不工作，未检测到 NVIDIA
- Deepin 20 beta：HDMI 不工作，NVIDIA 检测到
- 基本操作系统：HDMI 工作，检测到 NVIDIA
- Ubuntu >=15：HDMI 工作并且检测到 NVIDIA
我的电脑设置：
- 笔记本电脑 Lenovo ideapad L340 Gamer
- NVIDIA GeForce GTX 1050 3GB

答案1
我能建议的最好方法是研究一下 NVidia Optimus 驱动程序。https://wiki.archlinux.org/index.php/NVIDIA_Optimus
该端口可能已通过驱动程序禁用。
nvidia/intel GPU 在笔记本电脑中的布局方式有一些时髦的架构，一个 GPU 控制 HDMI 端口，另一个控制平板显示器的 LVDS 输出。这种架构一直是 VFIO/GPU 直通人群头疼的问题。
答案2
你能粘贴输出xrandr --verbose
如果出现 HDMI 输出，您可以手动添加显示器：
xrandr --newmode $(cvt 1920 1080 60.00 | sed -e '/Mode/s/.*"/1920x1080my/')
xrandr --addmode HDMI-1 1920x1080my
xrandr --output HDMI-1 --mode 1920x1080my
