## 固件

### 安全启动

2021年1月之后，删除系统自带的安全启动秘钥并安装用户自己的秘钥（如使用KeyTool）将会使设备变砖。这个问题与其他联想笔记本上出现的问题相似，可能是由于固件中的错误导致的。如果在更换安全启动秘钥后设备陷入无限循环的重启中，惟一的修复方法就是更换主板。希望这个问题能够在未来的固件升级中得到修复。

### 电池问题

在一个持续更新的论坛帖子中，出现了关于待机/关机状态下电池消耗过快的讨论。目前估计使用AMD雷诺阿架构CPU及其相关硬件的笔记本都会受到影响。由于1.30版本的BIOS可能会导致关机状态下电池电量在2-3天内减少50%，目前建议使用1.29版本的BIOS。

另外有意见指出，升级内核应该可以解决这个问题。联想和Canonical正在着手解决这个问题。

## AMD显卡

开源的AMD显卡驱动无需任何特别修改即可正常工作。

如果想在Chromium浏览器中开启硬件加速视频解码功能，安装libva-mesa-driver、vulkan-radeon及mesa-vdpau软件包，创建文件`~/.config/chromium-flags.conf`，将下列内容粘贴至创建的文件中：

    --ignore-gpu-blocklist
    --use-gl=desktop
    --enable-gpu-rasterization
    --enable-zero-copy
    --ignore-gpu-blacklist
    --disable-gpu-driver-bug-workarounds
    --enable-accelerated-video-decode

重新启动Chromium浏览器，并确认`chrome://gpu`的输出内容与下列内容一致：

    Canvas: Hardware accelerated
    Compositing: Hardware accelerated
    Multiple Raster Threads: Enabled
    Out-of-process Rasterization: Disabled
    OpenGL: Enabled
    Hardware Protected Video Decode: Hardware accelerated
    Rasterization: Hardware accelerated on all pages
    Skia Renderer: Enabled
    Video Decode: Hardware accelerated
    Vulkan: Disabled
    WebGL: Hardware accelerated
    WebGL2: Hardware accelerated

向下滚动很多行后应该会看到以下内容：

    Video Acceleration Information
    Decode h264 baseline	16x16 to 4096x4096 pixels
    Decode h264 main	16x16 to 4096x4096 pixels
    Decode h264 high	16x16 to 4096x4096 pixels
    Decode vp9 profile0	16x16 to 8192x4352 pixels

更多内容请参考Chromium#Force GPU acceleration及vaapi on linux。

## 指纹传感器

指纹传感器在近期更新的固件及近期升级的软件支持下工作正常。

1. 使用fwupd安装“Synaptics Prometheus Fingerprint Reader”的最新固件。相关固件为Prometheus Fingerprint Reader和Prometheus Fingerprint Reader Configuration。
2. 需要fprintd版本≥1.90.1且libfprint版本≥1.90.1。也可以安装fprintd-libfprint2AUR和libfprint-gitAUR使用最新的开发版本。

fprint页面包含安装指纹传感器的更多细节，如以PAM为基础的身份验证。

如果fwupd未能检测到指纹传感器，但是`lsusb`可以检测到，你需要在BIOS中重置指纹传感器。

## 背光

通过修改`/sys/class/backlight/amdgpu_bl0/brightness`文件中的值（范围0-255），背光可以正常工作。也可以通过背光调节软件控制背光。

如果使用比内核版本5.8.6更早的内核，需要禁用`systemd-backlight@backlight:acpi_video0.service`，因为该单元会启动失败。

## 休眠

S3级别的休眠需要在BIOS中设定Config -> Power -> Sleep to Linux。

## 智能卡读卡器

似乎可以正常工作，能够读取卡片。具体用法可参考smartcards

## 移动宽带

xmm7360-pci经测试可正常使用，具体参考Xmm7360-pci。

    $ lspci | grep XMM
    05:00.0 Wireless controller [0d40]: Intel Corporation XMM7360 LTE Advanced Modem (rev 01)

## 无线局域网

板载无线局域网卡型号为Intel AX200，直接使用可能会存在处理器微码方面的问题。对于WiFi断连的一个可能的解决方案是打开iwlwifi天线聚合，具体方法为创建一个modprobe配置：

    /etc/modprobe.d/iwlwifi.conf

    options iwlwifi 11n_disable=8

之后重启。详情参照Network configuration (简体中文)/Wireless (简体中文)#iwlwifi。
