The Direct Rendering Manager and KMS are part of the Linux kernel. The KMS does only the mode setting. Mode setting is a software operation that activates a display mode (screen resolution, color depth, and refresh rate) for a computer's display controller by using VESA BIOS Extensions or UEFI Graphics extensions (on more modern computers).
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.
Linux-based workstations are usually capable of having multiple displays, among which the user can switch with a special keyboard combination such as control-alt-function-key, simultaneously flipping all the monitors from showing the screens of one display to the screens in another.

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.
A compatibility layer avoids both the complexity and the speed penalty of full hardware emulation. Some programs may even run faster than the original, e.g. some Linux applications running on FreeBSD's Linux compatibility layer may perform better than the same applications on Red Hat Linux. Benchmarks are occasionally run on Wine to compare it ...
"Compatibility View" is a compatibility mode feature of the web browser Internet Explorer in version 8 and later. When active, Compatibility View forces IE to display the webpage in Quirks mode as if the page were being viewed in IE7. [1] [2] When compatibility view is not activated, IE is said to be running in native mode. In IE11, a user can ...
Linux API, Linux ABI, and in-kernel APIs and ABIs. The Linux kernel provides multiple interfaces to user-space and kernel-mode code that are used for varying purposes and that have varying properties by design. There are two types of application programming interface (API) in the Linux kernel: the "kernel–user space" API; and; the "kernel ...
