几天前拿到了这台设备（Lenovo Legion 5 Gen 6），在其上设置 Ubuntu（与 Windows 一起双启动）真的很麻烦。Wifi 开箱即用，发现其上的联发科 MT7921e Wifi 卡仅适用于内核 5.12 及以上版本。所以我运行的是自带的 Ubuntu 21.10 5.13.0-21-generic。
目前，我无法调整设备上的亮度级别。它设置为混合模式，配备 Ryzen 7 5800H CPU 和 Nvidia RTX3060 GPU（通过 Windows Lenovo Vantage/BIOS）。
我尝试了多种解决方案，包括设置内核参数 GRUB_CMDLINE_LINUX="amdgpu.backlight=0"。这里。
也尝试过
acpi_backlight=vendor
acpi_backlight=video
acpi_backlight=native等等，但无济于事。

另外，注意到driver部分Display是空的，如果这可能是一个问题。我已经xserver-xorg-video-amdgpu安装了。
我避免使用独立显卡或任何仅调整伽马值的软件。
答案1
（来源）以下是我所做的。
- 您可以使用
mainline安装内核版本 5.16.1 RC1，它即可开箱即用。 - 重新启动，选择恢复模式，启用网络并转到根终端。
- 全新安装 nvidia 驱动程序：
sudo apt purge nvidia-*然后sudo ubuntu-drivers autoinstall
