Needs nVidia driver information

KMS (Kernel Mode Setting) allows setting the display resolution in kernel space instead of userspace. This allows setting native screen resolutions early in the system boot process and can reduce flickering, both when booting and when switching ttys.

Enabling KMS requires adding kms to the mkinitfs configuration by adding it to the features variable, e.g:

Contents of /etc/mkinitfs/mkinitfs.conf

features="keymap cryptsetup kms ata base ide scsi usb virtio ext4"

Additional driver or firmware is required depending on the hardware in use:
