Knoppix booting on the framebuffer. The Linux framebuffer (fbdev) is a linux subsystem used to show graphics on a computer monitor, typically on the system console. [1]It was designed as a hardware-independent API to give user space software access to the framebuffer (the part of a computer's video memory containing a current video frame) using only the Linux kernel's own basic facilities and ...
DirectFB (Direct Frame Buffer), now continued as DirectFB2, is a software library with a small memory footprint that provides graphics acceleration, input device handling and abstraction layer, and integrated windowing system with support for translucent windows and multiple display layers on top of the Linux framebuffer without requiring any kernel modifications.
RFB ("remote framebuffer") is an open simple protocol for remote access to graphical user interfaces. Because it works at the framebuffer level it is applicable to all windowing systems and applications, including Microsoft Windows, macOS, the X Window System and Wayland. RFB is the protocol used in Virtual Network Computing (VNC) and its ...
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.
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.
Many systems attempt to emulate the function of a framebuffer device, often for reasons of compatibility. The two most common virtual framebuffers are the Linux framebuffer device (fbdev) and the X Virtual Framebuffer . Xvfb was added to the X Window System distribution to provide a method for running X without a graphical framebuffer. The ...
The Linux console is a system console internal to the Linux kernel. A system console is the device which receives all kernel messages and warnings and which allows logins in single user mode. [1] The Linux console provides a way for the kernel and other processes to send text output to the user, and to receive text input from the user.
Knoppix is a 32-bit Debian Linux based distro, but recent releases (including the latest version 7.6) have also been equipped with a 64-bit kernel on the DVD edition, where it will automatically boot up for 64-bit computers, or by using the boot option knoppix64 manually in the command-line prompt, while knoppix will boot up the 32-bit kernel ...
