sudo usermod -aG dialout username平板型号 酷比魔方 U100GT 2+32G 之前在平板上安装过debian11系统，也成功的安装好了klipperscreen正常显示，但无奈debian系统认不到rtl8723be的无线网卡，还是决定重新找一个能无线网卡正常使用的linux版本，bodhilinux ，这个linux系统是基于ubuntu 20.04的 安装好触摸正常，无线正常，稳定性也好，开机一晚上未死机，熄屏唤醒也正常，这次简单记录了一下安装过程中出现的错误及解决方法。
一、系统安装
https://www.bodhilinux.com/ 下载最新64位版本，将bootia32.efi复制到/efi/boot目录下才能启动安装界面，文件下载地址。安装过程略过。。
二、使用安装助手安装klipper\moonraker\fluidd或者。。。
cd ~
git clone https://github.com/th33xitus/kiauh.git
./kiauh/kiauh.sh安装步骤略过。。klipper 和fluidd的安装教程很多。
三、安装klipperscreen
在安装klipperscreen的过程中会报很多错误。下面将我记录的错误提示记录一下。

sudo vim /etc/X11/Xwrapper.configneeds_root_rights = yes编辑上面的文件 加上这一句
sudo chown pi /dev/tty2 #这句也执行过，不知道有没有用pi是我设置的用户名还是显示的系统原有的桌面
卸载原有桌面
查看/etc/init.d下有lightdm
sudo apt-get remove lightdm卸载了桌面 画面就有显示了，手动显示代码：
DISPLAY=localhost:0 /home/pi/.KlipperScreen-env/bin/python /home/pi/KlipperScreen/screen.py -c /home/pi/klipper_config/KlipperScreen.conf还有一些命令忘记了是不是运行过，也记录一下。
sudo apt-get install libcairo2-dev
sudo apt install libc6
sudo apt install libffi8
sudo apt install libgirepository1.0-dev
sudo apt install xinit
sudo apt install xinit xorg
sudo apt remove phosh
sudo apt install xserver-xorg-input-libinput安装好后的图片
