VirtualBox User ID and Password for Unattended Installation
Here’s the VirtualBox default user id and password, and how to enable and disable unattended installation.
The Oracle team completely changed the VirtualBox VM creation user interface from the VirtualBox 7.0 release. The multi-screen wizard is replaced by one single screen (here’s a tutorial showing the new screens).
Most of the options remain the same. However, a new option is introduced in VirtualBox 7.0, which is “unattended installation”. This is available under the “Name and operating system” section as a toggle check box.

Mouse cursor is not visible in Fedora and Wayland [Fixed]
Is your mouse cursor not visible in Wayland sessions in Fedora or Ubuntu? This is how you can fix it.
Many users have reported a recent issue over the web, which caused your mouse cursor to become invisible in the Wayland session. I personally also got this error in the latest Fedora 37 workstation with GNOME 43 Wayland session.
The behaviour is like when your cursor arrives in a certain GTK window, the cursor becomes invisible. However, you can still see the cursor focus in the target window. This includes the pointer, the resize handle and everything related to the cursor theme.

Automatically Change Power Mode in Ubuntu 22.04 base on Power Supply | UbuntuHandbook
Want to change system power mode between Performance, Balanced, and Power Saver automatically when plug / un-plug power supply?
Here’s an extension can do the job for Ubuntu 22.04, Ubuntu 22.10, Fedora 36/37, Arch and other Linux with GNOME 42 & 43.
GNOME introduced setting options to switch power mode since v40. For laptop running on AC power supply, user may use ‘Performance’ mode for gaming or doing heavy work. To prevent from draining power fast after un-plug AC power, it’s better to switch to ‘Balanced’ mode, or even ‘Power Saver’ mode when battery level is low. To automate this work, ‘Power Profile Switcher’ extension was born.
