thinkpad linux 笔记本连接 HDMI 显示器，没有输出，没有反映。 其他笔记本电脑测试可以正常输出。
主要报错如下：
[ 15.471218] [drm:lspcon_init [i915]] ERROR Failed to probe lspcon
[ 15.471263] [drm:intel_dp_detect [i915]] ERROR LSPCON init failed on port D
试过 5.10,5.15 的内核都不行，我不知道是不是因为 thinkpad 笔记本有问题。 更换内核不起作用。
郑重说明，和 nvidia 显卡驱动无关,这个是 intel 核显
补充：thinkpad 我换成安装 ubuntu 系统，也是出现这种情况，就是显示器 HDMI 没有输出。 但是没有报以上的错误。 注明：我的 CPU 是 i9 10 代

For me this issue has actually _appeared_ recently, about 1-2 weeks ago, not more. After the kernel upgrade.
Running 5.14.6-arch1-1 now, everything up to date. On Lenovo T15g Gen1 laptop, with integrated Intel card + Nvidia prime. Not connected to the external monitor. The following messages pop up on the console every time the machine wakes up:

大概率是 Intel 核显驱动 bug ，这种情况普通用户基本只能等修复了。
我手头上有台 i7-6700 的台式机，Linux 下核显就是不能正常工作，试过 CentOS 7, Ubuntu 20.04 和 Ubuntu 21.10 都不行，换成 Windows 就很正常。
