Steps

1. Install the Kubuntu22.04 operating system

1.1. It is recommended to install the original Kubuntu system (History of Blood and Tears)

1.1.1 If you install kubuntu-desktop on the Ubuntu system, there are many pitfalls for you to step on. For example, if the parameter is not selected correctly, you will suddenly be unable to enter the system, or the login interface may log in repeatedly.
1.1.2 And Kubuntu is installed with Nvidia driver, if it is Ubuntu, Nvidia driver should be installed, stepping on more pitfalls

If you have already installed kubuntu-desktop, then omit all the above words; if not, and your system is just installed, then it is strongly recommended to reinstall the Kubuntu system, one step in place

Kubuntu download URL: https://kubuntu.org/getkubuntu/

2. Install the Wallpaper Engine Kde Plugin

2.1 Method 1 (installation of the system’s own wallpaper plug-in) (not recommended: the domestic network generally cannot be installed):

2.1.1 Switch to desktop
2.1.2 Right mouse button to configure desktop and wallpaper
2.1.3 Click to get new plug-ins

2.1.4 Find Wallpaper Engine Kde Plugin, click to install

2.2 Method 2 (download the installation package from the official website of Wallpaper Engine Kde Plugin and install it manually) (recommended):

(Download plug-in installation package: choose one of the two)
2.2.1 Download from the official website of the plug-in (not recommended, the installation package cannot be downloaded from the domestic network): https://store.kde.org/p/1475528

2.2.2 Baidu Netdisk (recommended): https://pan.baidu.com/s/1WJtrUJkJTLb8PZRP3t11Sw?pwd=linx
Password: linx

Here the directory where I downloaded the installation package is: ~/Download
Enter the following command to install the plugin

cd ~/Download
// install the plugin
kpackagetool5 -t Plasma/Wallpaper -i we-kde-0.5.4.tar.gz

3. Download and build Wallpaper Engine for Kde engine

3.1 download and build, install a higher version of python (3.5 + )? very important

Description: The python that comes with kubuntu22.04 is python3.10, but the required python is 3.5 + , if you use the python that comes with kubuntu , there will be some problems later, such as some wallpapers cannot be played at all, etc., but this problem will not occur if you switch to the required version of python.

Warning: Do not uninstall the python3.10 that comes with the system. Many system programs depend on python3.10. If you uninstall it, the system will not be able to enter (I stepped on a big hole!!!)

3.1.1 Since the highest and safe version of python is 3.9, I choose python3.9.16 to download

Official website URL: https://www.python.org/downloads/release/python-3916/

3.1.2 Unzip after downloading the installation package, you can right-click on the graphical interface to unzip

Tips: The –prefix parameter is used to specify the installation directory of the software. If this parameter is added, executable files, library files, modules, etc. will be placed in the modified directory; if not added, it can be executed Files, library files, modules, etc. will be split by default and installed in the /usr/local/bin and /usr/local/lib directories of the system

3.1.3 build python3.9.16

cd into the decompressed python folder
./configure --prefix=/usr/local/python3 --enable-optimizations
make
sudo make install

So python3.9.16 is installed
Tips: The software we install ourselves is generally placed in the /usr/local directory

Tips: We usually use the python command in the terminal to call the python file in the /usr/bin directory, and this file is usually a soft link file, which is equivalent to a pointer, which is also understandable It is a shortcut under the Windows system. The python soft link file is used to call the actual python file, so that we can directly enter the python environment by typing python in the terminal. If there is no python file under /usr/bin, then you enter python is There will be no response. At this time, you can enter python3.10 to enter the python environment, because there is a python3.10 file under /usr/bin in this system. Generally, /usr/bin is added to the $PATH environment variable. , which is equivalent to Windows, right click on the computer, advanced, the Path environment variable under the system environment, so that commands can be executed at any terminal.

3.1.4 Create soft links of python3 and pip3

// Delete the python3 and pip3 soft link files under the original /usr/bin
rm -rf /usr/bin/python3
rm -rf /usr/bin/pip3

//Add a soft link, and then enter python3 or pip3 to enter the environment
//Add a soft link to python3
ln -s /usr/local/python3/bin/python3.9 /usr/bin/python3
//Add the soft link of pip3
ln -s /usr/local/python3/bin/pip3.9 /usr/bin/pip3

Enter python3 -V and pip3 -V to check whether it is installed

Lenovo-Legion-R7000P2020H:~$ python3 -V
Python 3.9.16

Lenovo-Legion-R7000P2020H:~$ pip3 -V
pip 22.0.4 from /usr/local/python3/lib/python3.9/site-packages/pip(python 3.9)

Find a file in the opened folder to check the path, and find out if it is the same as the default ~/.local/share/Steam path of the wallpaper, then the path of your computer to store the wallpaper is above The icon is red for this path, select it. In addition, folders starting with . are hidden folders, you can use ctrl + h to show hidden folders.
