HDMI不适用于带有Ubuntu22.10/22.04的Thinkpad T16

Question

我有一台全新的笔记本电脑(联想ThinkPad T16 Gen 1)，安装了Ubuntu22.10(我有22.04台电脑，认为升级系统+内核会解决问题)，到目前为止，我还没能让HDMI正常工作。如果我使用USB来减少HDMI监视器工作正常，但是当直接插入HDMI端口时它不会出现(我尝试了几个我知道是工作的监视器)。

当我离开HDMI连接并重新启动时，我可以看到联想的徽标，所以我知道HDMI没有损坏。它在启动屏幕后就停止工作了。

我尝试了几种解决方案(大多数都是在这个问题中总结的)，但到目前为止没有什么效果。

在软件更新中，我看到了->的附加驱动程序No additional drivers available。

我已经试过了

sudo apt-get purge 'nvidia*'
sudo add-apt-repository ppa:graphics-drivers
sudo apt-get update
sudo ubuntu-drivers autoinstall

但那不管用。

经过几天的斗争，我终于解决了这个问题。我的搜索引导我来到这里：https://forums.lenovo.com/t5/Other-Linux-Discussions/Thinkpad-T14-Gen-3-has-no-available-HDMI-ports-under-Linux/m-p/5147202?page=1

我用sudo dmidecode -s bios-version检查了我的BIOS版本，发现它是1.01。因此，最后我将我的BIOS更新为当前版本，然后它开始工作:)

他们甚至在信息txt文件中提到了这个错误。
