迷你触屏电脑安装klipper用于3D打印上位机
前面发了视频安装过程，现在将命令内容发布在此。
2023.2.16更新，以下步骤中的部分方法经过更新，可能和视频有所出入，按文本为准。
步骤一
Debian镜像下载地址
https://cdimage.debian.org/cdimage/unofficial/non-free/cd-including-firmware/current/multi-arch/iso-cd/
制作好系统的安装U盘后，下载
http://mirrors.ustc.edu.cn/debian/pool/non-free/f/firmware-nonfree/firmware-realtek_20210315-3_all.deb
放到安装U盘的firmware目录下。
插上U盘和网线，引导进安装初始界面，选择第二个，install，根据提示安装系统。
最后一步不选择安装桌面，只选择SSH server和标准系统工具。
重启后在设备上执行命令
ip address
查看IP地址。
步骤二
使用SSH工具，用root用户远程登陆设备。
执行命令
nano /etc/network/interfaces
如果使用WiFi连接，复制下面的内容增加到最后面，使用网线的不需要操作
auto wlan0
iface wlan0 inet dhcp
wpa-ssid 777
wps-psk 1122334455
#WiFi隐藏时取消下面这行前面的#
#wpa-scan-ssid 1
按键盘 CTRL+O，回车，CTRL+X
完整复制下面的命令到SSH客户端执行，替换源：
cat > /etc/apt/sources.list << EOF

分别执行下面2行命令，安装依赖程序
apt-get update
apt-get install firmware-linux-free firmware-linux-nonfree firmware-misc-nonfree firmware-myricom firmware-netronome firmware-netxen firmware-qcom-soc firmware-qlogic firmware-realtek firmware-samsung firmware-siano firmware-sof-signed firmware-ti-connectivity firmware-zd1211 hdmi2usb-fx2-firmware intel-microcode amd64-microcode atmel-firmware bluez-firmware dahdi-firmware-nonfree firmware-amd-graphics firmware-ath9k-htc firmware-atheros firmware-b43legacy-installer firmware-bnx2 firmware-bnx2x firmware-brcm80211 firmware-cavium firmware-intel-sound firmware-intelwimax firmware-ipw2x00 firmware-ivtv firmware-iwlwifi firmware-libertas fonts-wqy-zenhei git sudo unzip net-tools wireless-tools -y
为用户samuel添加sudo权限，samuel替换为你自己的新用户名
usermod -a -G sudo samuel
执行下面命令，将用户添加到dialout用户组和tty用户组
gpasswd --add samuel dialout && gpasswd --add samuel tty && gpasswd --add samuel input
重启系统
reboot
步骤三
在SSH客户端使用自己新建的用户远程登陆

步骤五
安装KlipperScreen
cd ~ && git clone https://github.com/jordanruthe/KlipperScreen.git && cd ~/KlipperScreen && ./scripts/KlipperScreen-install.sh
提示需要重启，确定重启
问题处理
重启后屏幕不显示KlipperScreen界面，执行（samuel为用户名，自行修改）
cat /home/samuel/.local/share/xorg/Xorg.0.log
如果日志里有类似错误
(EE) xf86OpenConsole: Cannot open virtual console 2 (Permission denied)
执行
sudo nano /etc/X11/Xwrapper.config
在末尾添加一行
needs_root_rights=yes
然后执行
sudo dpkg-reconfigure xserver-xorg-legacy && sudo reboot
重启后，屏幕显示转了90度，需要永久化屏幕旋转
sudo /bin/sh -c "cat > /usr/share/X11/xorg.conf.d/90-monitor.conf" << EOF
Section "Monitor"
Identifier "DSI-1"
Option "Rotate" "left"
# Valid rotation options are normal,inverted,left,right
#Option "PreferredMode" "1920x1080"
# May be necesary if you are not getting your prefered resolution.
EndSection
EOF
重启KlipperScreen服务
sudo service KlipperScreen restart
如果试了还是不翻转，将前面的Identifier "DSI-1"修改为Identifier "DPI-1"后，再重复上面2步操作。
此时触摸还未旋转，执行下方命令测试触摸旋转
DISPLAY=:0 xinput set-prop "pointer:Goodix Capacitive TouchScreen" 'Coordinate Transformation Matrix' 0 -1 1 1 0 0 0 0 1
测试没有问题，修改成永久化触摸旋转
sudo nano /usr/share/X11/xorg.conf.d/40-libinput.conf
在有touchscreen的里面添加一行 Option "TransformationMatrix" "0 -1 1 1 0 0 0 0 1"
修改后如下：
Section "InputClass"
Identifier "libinput touchscreen catchall"
MatchIsTouchscreen "on"
MatchDevicePath "/dev/input/event*"
Driver "libinput"
Option "TransformationMatrix" "0 -1 1 1 0 0 0 0 1"
EndSection
