【树莓派4B】Manjaro-ARM系统下配置VNC以及遇到的问题

在两三个小时内经历了各种尝试之后，终于成功，现在记录一下过程，以免下次忘记

系统：
我实在树莓派4B 8G版上安装了Manjaro

1.下载

wget https://github.com/azalinux/realvnc-server-aarch64-manjaro/releases/download/realvnc-vnc-server-6.7.2.43081-1-aarch64/realvnc-vnc-server-6.7.2.43081-1-aarch64.pkg.tar.zst
在manjaro上点击上面的链接下载

2.安装：

manjaro系统的打包格式认准.zst,双击应该就可以安装了（我这次是在浏览器里直接打开的）
如果不能，用下面这个命令：

pacman -U realvnc-vnc-server-6.7.2.43081-1-aarch64.pkg.tar.zst

完事之后就安装成功了

3.配置三项：

sudo systemctl enable vncserver-x11-serviced.service
sudo systemctl start vncserver-x11-serviced.service
sudo systemctl status vncserver-x11-serviced.service

第一条是设置开机启动VNC，第二条是开始VNC服务，第三条是查看VNC的状态。如果操作都正确，则将会显示其为active(running)状态。

4.成功：

5.但是开始的时候遇到了2个问题：

问题1.我已经设置了开机自动登录（系统设置->开机与关机->行为设置）
开机还是会提示输入“KDE钱包服务”密码，输入系统密码后即可，不然vnc不能用。
解决：左下角，搜索，kwalletmanager，没有的话去系统商店安装，之后打开kwalletmanager更改密码为系统密码一致，其次打开KDE钱包，取消“启用KDE钱包子系统”。

问题2.，解决问题1之后，重启，wifi密码提示重新输入，每次开机都要输入哪行.
解决：右键右下角wifi图标，配置网络连接，WIFI安全，输入密码保存即可解决。

第二天又又又遇到了新问题：不连接显示屏的情况下就不给开机

解决：/boot/config.txt文件内增加以下内容：

hdmi_force_hotplug=1
hdmi_group=2
hdmi_mode=82

hdmi_force_hotplug=1 伪装成HDMI热插拔信号被检测到, 出现HDMI显示器被接入；即便没有检测到HDMI显示器也要使用HDMI模式

hdmi_group=2 设置HDMI类型为DMT，不指定组, 或者设为0, 将会使用EDID报告的首选组.

hdmi_mode=82 设置在CEA或DMT格式下的屏幕分辨率为1080p 60Hz

参考：树莓派配置文件config.txt详细介绍

6.vnc如果还不行，参考:

1.github：https://github.com/azalinux/realvnc-server-aarch64-manjaro

realvnc-server-aarch64-manjaro
RealVNC Server for Raspberry Pi4 64bit Manjaro AARCH64

This AUR package will install RealVNC Server aarch64 package on any
Manjaro ArchLinux based ARM64 installation on a Raspberry Pi4.

Has been tested on all flavours of Manajaro ARM64 flavours using a 8gb
Raspberry Pi 4b. Has also been tried on XFCE, MATE & KDE Plasma
desktop flavours.

BEFORE YOU INSTALL THIS PACKAGE:

Make sure you have the package base-devel installed fully. For
example, a default install of Manjaro Arch ARM64 only has some
components of base-devel installed by default on a fresh installation
so please perform the following command to ensure all prerequists for
building the package are met: pacman -S base-devel

Installation:

You can use the precompiled package in my Releases page to download &
install:

wget
https://github.com/azalinux/realvnc-server-aarch64-manjaro/releases/download/realvnc-vnc-server-6.7.2.43081-1-aarch64/realvnc-vnc-server-6.7.2.43081-1-aarch64.pkg.tar.zst

pacman -U realvnc-vnc-server-6.7.2.43081-1-aarch64.pkg.tar.zst

OR git clone this package to compile manually:

git clone
https://github.com/azalinux/realvnc-server-aarch64-manjaro.git

makepkg -si

FYI: This should be pre-activated as the source is pre-activated for
use with Raspberry Pi’s however if it doesn’t show a valid license
after installation, you will need a valid realvnc key; to activate
run: sudo /usr/bin/vnclicense -add

Don’t forget to enable the systemd service: sudo systemctl enable
vncserver-x11-serviced.service

And thats it! A working 64bit RealVNC server running on Manjaro
ArchLinux ARM64!

Please note - This free Raspberry Pi edition of RealVnc Server will
let clients connect via TCP direct mode rather than UDP direct mode.
You need an Enterprise License to connect via UDP!
