我有一台全新的笔记本电脑（Lenovo ThinkPad T16 Gen 1），安装了 Ubuntu 22.10（我之前使用的是 22.04，以为升级系统 + 内核可以解决这个问题），到目前为止，我还没能让 HDMI 工作。如果我使用 USB-C 转 HDMI 转换器，显示器可以正常工作，但直接插入 HDMI 端口时，它不会显示（我试过几台我知道可以工作的显示器）
当我保持 HDMI 连接并重新启动时，我可以看到联想徽标，所以我知道 HDMI 没有损坏。它在启动屏幕后立即停止工作。
我尝试了几种解决方案（大多数总结在这个问题)，但目前还没有任何效果。
在软件更新->附加驱动程序中我看到No additional drivers available。
我已经尝试过了
sudo apt-get purge 'nvidia*'
sudo add-apt-repository ppa:graphics-drivers
sudo apt-get update
sudo ubuntu-drivers autoinstall
但那没有用。

经过几天的努力，我终于解决了这个问题。我的搜索结果如下： https://forums.lenovo.com/t5/Other-Linux-Discussions/Thinkpad-T14-Gen-3-has-no-available-HDMI-ports-under-Linux/mp/5147202?page=1
我检查了我的 BIOS 版本，sudo dmidecode -s bios-version发现是 1.01。所以最后我将 BIOS 更新为当前版本，然后它就开始工作了 :)
他们甚至在信息 txt 文件。
<1.27>
UEFI: 1.27 / ECP: 1.12
- (Fix) Fixd HDMI port is useless in Linux OS.
