Free and open-source drivers are primarily developed on and for Linux by Linux kernel developers, third-party programming enthusiasts and employees of companies such as Advanced Micro Devices. Each driver has five parts: A Linux kernel component DRM; A Linux kernel component KMS driver (the display controller driver)
It is a replacement for the previous Windows 2000 and Windows XP display driver model XDDM/XPDM [3] and is aimed at enabling better performance graphics and new graphics functionality and stability. [2] Display drivers in Windows Vista and Windows 7 can choose to either adhere to WDDM or to XDDM. [4]
Driver Verifier is a tool included in Microsoft Windows that replaces the default operating system subroutines with ones that are specifically developed to catch device driver bugs. [1] Once enabled, it monitors and stresses drivers to detect illegal function calls or actions that may be causing system corruption. It acts within the kernel mode ...

The display driver may itself be an application-specific microcontroller and may incorporate RAM, Flash memory, EEPROM and/or ROM. Fixed ROM may contain firmware and display fonts. A notable example of a display driver IC is the Hitachi HD44780 LCD controller. Other controllers are KS0108, SSD1815 (graphics capable) and ST7920 (graphics capable)
In the context of an operating system, a device driver is a computer program that operates or controls a particular type of device that is attached to a computer or automaton. [1] A driver provides a software interface to hardware devices, enabling operating systems and other computer programs to access hardware functions without needing to ...
The OS will then do a bunch of other recovery steps needed for the system to regain responsiveness. If the entire operation was successful, the end user might see some visual artefacts and a message will be shown on the screen describing what had happened ("Display driver stopped responding and has recovered."), else a BSOD might ensue.
