If you are doing it to enhance GUI desktop (gdm or etcetera) then ensure you have the appropriate packages installed; Oracle’s VirtualBox (VBox) Guest Additions do not require video in general.
If however, you are having difficulties seeing your mouse cursor within the desktop environment and your ALMALinux machine is running with Oracle VBox you need to install the Guest Additions.
So, here are the steps:
- dnf update -y
- dnf install kernel-headers kernel-devel gcc cpp perl make elfutils-libelf-devel
- “Insert the ISO into the virtual dvdrom drive”
- Execute the following command: VBoxLinuxAdditions.run
From here things should be completed. The mouse cursor should finally be visible.
