	The '''Direct Rendering Manager''' ('''DRM''') is a subsystem of the [[Linux kernel]] responsible for interfacing with [[Graphics processing unit\|GPUs]] of modern [[video cards]]. DRM exposes an [[Application programming interface\|API]] that [[user-space]] programs can use to send commands and data to the GPU and perform operations such as configuring the [[mode setting]] of the display. DRM was first developed as the [[kernel-space]] component of the [[X.Org Server\|X Server]] [[Direct Rendering Infrastructure]],{{r\|DRM readme}} but since then it has been used by other graphic stack alternatives such as [[Wayland (display server protocol)\|Wayland]] and standalone applications and libraries such as [[Simple DirectMedia Layer \| SDL2]] and [[Kodi (software) \| Kodi]].
