The headline is misleading. It is indeed KMS support (Kernel Mode Setting), which enables the kernel (and not the graphic driver) to control the display modes. This is better:<p>1. For boot (no flicker when the graphic driver takes over);<p>2. For errors (for instance to display kernel errors) and to stay in graphic mode even when X hangs;<p>3. It enables to run X as an underprivileged user: So it&#x27;s cleaner and can add security.
