最近购买Redmi 或 Lenovo刚发布的AMD R7 6800H机型的朋友们，安装deepin后遇到的问题如下：

• 1、内置键盘无法使用，USB外置键盘正常。
• 2、WIFI没有驱动 - （螃蟹卡 8852be）。
• 3、蓝牙没有驱动 - (螃蟹卡 8852be)。
• 4、开启窗口特效后，kwin_x11进程CPU占用飙升。
• 5、电源管理，无论怎么调，笔记本都发热很严重。

首先，安装deepin20.06，必须选择内核5.15以上，保证没有其他遗留问题。

1、修复内置键盘无法使用

sudo su
mkdir -p /home/dsdt
cd /home/dsdt
cat /sys/firmware/acpi/tables/DSDT > dsdt.dat
apt install acpica-tools
iasl -d dsdt.dat

# 开始编辑 dsdt.dsl
vim dsdt.dsl

# 搜索并替换 Device(KBC0) 下面的
IRQ (Edge, ActiveLow, Shared, ) 
  => 
Interrupt (ResourceConsumer, Edge, ActiveLow, Shared, ,, )

# 搜索DefinitionBlock，将定义的 DefinitionBlock 递增1，如果是0x00000001，则修改为0x00000002，如果是0x00000002，则修改为0x00000003
DefinitionBlock ("", "DSDT", 1, "LENOVO", "CB-01   ", 0x00000001)
  => 
DefinitionBlock ("", "DSDT", 1, "LENOVO", "CB-01   ", 0x00000002)

# 保存并关闭 dsdt.dsl

iasl dsdt.dsl

mkdir -p kernel/firmware/acpi
cp dsdt.aml kernel/firmware/acpi/
find kernel | cpio -H newc --create > acpi_override
cp acpi_override /boot/acpi_override
echo "GRUB_EARLY_INITRD_LINUX_CUSTOM=\"acpi_override\"" >>/etc/default/grub

# 更新并重启
update-grub2
reboot
​

2、修复wifi驱动

# 内核小于5.18的
git clone https://github.com/HRex39/rtl8852be.git
# 内核大于等于5.18的
git clone https://github.com/HRex39/rtl8852be.git -b dev

cd rtl8852be
make -j8
sudo make install
sudo modprobe 8852be
​

3、修复蓝牙驱动

# 内核=5.15
git clone https://github.com/HRex39/rtl8852be_bt.git -b 5.15
# 内核=5.18
git clone https://github.com/HRex39/rtl8852be_bt.git -b 5.18

cd rtl8852be_bt
make -j8
sudo make install
​

4、kwin_x11开启窗口特效后cpu飙升，因为显卡未驱动

首先去amd官网下载最新的linux-amd驱动：

https://www.amd.com/zh-hans/support/linux-drivers // 22.20 for Ubuntu 20.04.5 HWE
​

修改Deepin为ubuntu

sudo vim /etc/os-release // ID=Deepin => ID=ubuntu
​

sudo apt install ./amdgpu-install_22.20.50200-1_all.deb
​

sudo vim /etc/apt/sources.list.d/amdgpu.list // focal => bionic
​

sudo apt update
​

sudo amdgpu-install --no-dkms
​

sudo apt install inxi clinfo
​

安装成功以后，用inxi查看下：

inxi -G

Graphics:  Device-1: AMD Rembrandt driver: amdgpu v: kernel 
           Display: x11 server: X.Org 1.20.11 driver: amdgpu,ati unloaded: fbdev,modesetting,vesa 
           resolution: 1920x1080~60Hz 
           OpenGL: renderer: AMD YELLOW_CARP (LLVM 14.0.1 DRM 3.42 5.15.34-amd64-desktop) 
           v: 4.6 Mesa 22.1.0-devel
​

最后还原最初的修改：

sudo vim /etc/os-release // ID=ubuntu => ID=Deepin
sudo apt purge amdgpu-install
​

5、电源管理无效，需要手动管理，避免CPU过度使用而发热

安装下面的三方电源管理工具 Boost Changer，选择 Performance策略即可

wget https://github.com/nbebaw/boostchanger/releases/download/v4.4.0/boostchanger_4.4.0_amd64.deb
