I installed the ubuntu21.04 system on my computer today and found that almost all commonly used screen recording tools cannot be used by default. Later I found out that it was because the graphical interface was replaced by Wayland, and the related tools still only support Xorg or similar graphical interface basis, let's take a look at the solution to this problem.
When entering the ubuntu login window, we click on the user name, and then select the ubuntu on Xorg option in the lower right corner.
For the newly installed ubuntu21.04, we need to firstsudo apt update Update our resource environment, otherwise many tools will prompt that they cannot be found.
Now we install the most commonly used screen recording tool sudo apt install kazam It’s good to try this yourself, especially the built-in screen recording Audio.
After completion, we still need simple configuration, which cannot be used directly, So we open the kazam window , select File--Preferences.
We adjust the volume of the speaker to the maximum and the microphone to the required volume. Because we don’t need a microphone, the volume is directly minimized.
Finally we set the frame rate, the recorded audio format, etc. Then go back to the main window and select Capture at the bottom to start recording the desktop.
The above is the detailed content of How to solve the problem that the screen recording tool cannot be used in ubuntu21.04 and understand its usage. For more information, please follow other related articles on the PHP Chinese website!


For years, Linux software distribution relied on native formats like DEB and RPM, deeply ingrained in each distribution's ecosystem. However, Flatpak and Snap have emerged, promising a universal approach to application packaging. This article exami

The differences between Linux and Windows in handling device drivers are mainly reflected in the flexibility of driver management and the development environment. 1. Linux adopts a modular design, and the driver can be loaded and uninstalled dynamically. Developers need to have an in-depth understanding of the kernel mechanism. 2. Windows relies on the Microsoft ecosystem, and the driver needs to be developed through WDK and signed and certified. The development is relatively complex but ensures the stability and security of the system.

The security models of Linux and Windows each have their own advantages. Linux provides flexibility and customizability, enabling security through user permissions, file system permissions, and SELinux/AppArmor. Windows focuses on user-friendliness and relies on WindowsDefender, UAC, firewall and BitLocker to ensure security.

Linux and Windows differ in hardware compatibility: Windows has extensive driver support, and Linux depends on the community and vendors. To solve Linux compatibility problems, you can manually compile drivers, such as cloning RTL8188EU driver repository, compiling and installing; Windows users need to manage drivers to optimize performance.

The main differences between Linux and Windows in virtualization support are: 1) Linux provides KVM and Xen, with outstanding performance and flexibility, suitable for high customization environments; 2) Windows supports virtualization through Hyper-V, with a friendly interface, and is closely integrated with the Microsoft ecosystem, suitable for enterprises that rely on Microsoft software.

The main tasks of Linux system administrators include system monitoring and performance tuning, user management, software package management, security management and backup, troubleshooting and resolution, performance optimization and best practices. 1. Use top, htop and other tools to monitor system performance and tune it. 2. Manage user accounts and permissions through useradd commands and other commands. 3. Use apt and yum to manage software packages to ensure system updates and security. 4. Configure a firewall, monitor logs, and perform data backup to ensure system security. 5. Troubleshoot and resolve through log analysis and tool use. 6. Optimize kernel parameters and application configuration, and follow best practices to improve system performance and stability.

Learning Linux is not difficult. 1.Linux is an open source operating system based on Unix and is widely used in servers, embedded systems and personal computers. 2. Understanding file system and permission management is the key. The file system is hierarchical, and permissions include reading, writing and execution. 3. Package management systems such as apt and dnf make software management convenient. 4. Process management is implemented through ps and top commands. 5. Start learning from basic commands such as mkdir, cd, touch and nano, and then try advanced usage such as shell scripts and text processing. 6. Common errors such as permission problems can be solved through sudo and chmod. 7. Performance optimization suggestions include using htop to monitor resources, cleaning unnecessary files, and using sy

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
