What is compatibility mode in Linux?

Compatibility mode blacklists a wifi driver b43 because of some freezing problems, disables fast graphics mode switching, disables the advanced configuration and power interface and doesn’t load the splash screen. That’s about it. Thanks.

How do I run Linux Mint in compatibility mode?

Use the “Compatibility mode” to boot and install Linux Mint. After the installation, use “Advanced Options” -> “Recovery mode” from the boot menu and choose “resume”.
