In the middle: the FOSS stack, composed out of DRM & KMS driver, libDRM and Mesa 3D.Right side: Proprietary drivers: Kernel BLOB and User-space components. nouveau (/ n uː ˈ v oʊ /) is a free and open-source graphics device driver for Nvidia video cards and the Tegra family of SoCs written by independent software engineers, with minor help from Nvidia employees.
X.Org Server is the free and open-source implementation of the X Window System (X11) display server stewarded by the X.Org Foundation.. Implementations of the client-side X Window System protocol exist in the form of X11 libraries, which serve as helpful APIs for communicating with the X server. [4]
The VDPAU interface is to be implemented by device drivers, such as the Nvidia GeForce driver, nouveau, or amdgpu, to offer end-user software, such as VLC media player or GStreamer, a standardized access to available video decompression acceleration hardware in the form of application-specific integrated circuit (ASIC) blocks on graphics ...
The file xorg.conf is a file used for configuring the X.Org Server. While typically located in /etc/X11/xorg.conf , its location may vary across operating system distributions (See manual, "man xorg.conf" for details and further possible locations).
The Foundation released X11R6.7, the X.Org Server, in April 2004, based on XFree86 4.4RC2 with X11R6.6 changes merged. Gettys and Packard had taken the last version of XFree86 under the old license and, by making a point of an open development model and retaining GPL compatibility, brought many of the old XFree86 developers on board.
There are two graphics hardware drivers: one resides inside of the X display server.There have been several designs of this driver. The current one splits it in two portions: DIX (Device-Independent X) and DDX (Device-Dependent X) Glamor will simplify the X server, and libGL-fglrx-glx [needs update] could use the libDRM of the radeon open-source driver instead of the proprietary binary blob.
The Direct Rendering Manager (DRM) is a subsystem of the Linux kernel responsible for interfacing with GPUs of modern video cards.DRM exposes an 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.
These are generally managed directly by XFree86, so it includes its own drivers for all graphic cards a user might have. Some cards are supported by vendors themselves via binary-only drivers. Since version 4.0, XFree86 has supported certain accelerated 3D graphics cards via the GLX and DRI extensions. Version 4.0 also moved to a new driver ...
