All the components of the LAMP server are available to install using the default system repository of Ubuntu. Hence, we can configure the environment without adding an extra repository. However, before moving forward, just run the system update command to ensure the system rebuilds the APT package index cache.
sudo apt update
We can install LAMP server components one by one on our Ubuntu system. However, it is a time-consuming process, hence to make it short here we are using a single command. That will not only install the LAMP server but also enable and start all the required services.
sudo apt install lamp-server^ php
The above command will select all the required packages to set up Apache, MySQL, and PHP on your system.
Well, when it comes to uninstalling the LAMP server completely from your Ubuntu system, we can use the given command:
sudo apt autoremove --purge apache2* mysql-server* php*
Webp is an open-source image format in Linux which supports lossless and lossy compression for images on the web.
One of the best practices to optimize the website performance is using compressed images.

Using the cwebp tool, an image can be converted into webp format. Run the cwebp command with option -q to define the quality of image and -o to define the output file.
In this example, I have used image file linux.png and linux.jpeg file to convert in webp format. You can choose your image name accordingly.
cwebp -q 60 linux.png -o linux.webp
cwebp -q 60 linux.jpeg -o linux1.webp
Converting webp image to png and jpeg format
In the previous step, we converted jpeg and png images to webp using cwebp utility tool. Now we will use the dwebp tool to convert webp images into png and jpeg format.
Use the dwep command with the option -o to create png and jpeg image format from webp. In the example, image.webp is used for the conversion.
dwep image.webp -o image.png
dwep image.webp -o image.jpeg
If you go to the Xfce menu and choose settings > settings manager > window manager tweaks > accessibility, you can select another key instead of alt to move the windows or choose none at all. This should be just what you want.
You can also use xfconf-query to set easy_click to none (or another key) on the command-line:
xfconf-query -c xfwm4 -p /general/easy_click -s none
