对于我正在处理的 LSPCON 检测问题，我将不胜感激。一台笔记本（联想IdeaPad S340）有i3-8145U，只有集成显卡Intel UHD 620带HDMI输出。我尝试过的每个内核（5.6.11、5.6.14、5.6.15）都无法正确检测 LSPCON：

这是我的uname
[email protected]:/home/matej# uname -a
Linux wks1.S340.local 5.6.15 #1 SMP Wed May 27 19:56:11 -02 2020 x86_64 Intel(R) Core(TM) i3-8145U CPU @ 2.10GHz GenuineIntel GNU/Linux
我有最新的 linux-firmware-20200519，我设置了这些引导标志，但没有成功：
acpi_osi=! acpi_osi='Windows 2009' pcie_aspm=off
我也试过关闭 modesetting: i915.modeset=0。
非常感谢您的时间和帮助。
