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.
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.
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).
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 X Window System (X11, or simply X; stylized 𝕏) is a windowing system for bitmap displays, common on Unix-like operating systems.. X originated as part of Project Athena at Massachusetts Institute of Technology (MIT) in 1984. [3]
The initial versions of the XRDP project relied on a local VNC server installation that had to be present alongside the program, in order to relay the graphics and controls between the user and the server [7] (known as the "VNC forwarding mode"). However, this mode is currently not recommended to use anymore, due to its slow performance.
Xvfb is also used for remote control. VNC over SSH can be faster than X11 over SSH, [4] specially reducing latency over the internet. [5] In this case, Xvfb is often combined with a lightweight window manager (such as Fluxbox or Openbox) and a VNC server such as X11vnc.
