Problems solved by technology

The versatility of graphics card support is low, the functions of the support library are limited, and the support for 3D effects is poor, so the graphics card cannot be used to a greater extent
[0005] The problem with the external graphics card driver is that when initializing the system, the user needs to know the hardware information of the graphics card in order to configure the correct graphics card driver.
Or, after the user replaces the graphics card, a new graphics card driver needs to be reconfigured, which increases the difficulty of using the graphics card

Abstract

The invention discloses a display card driving device of a Linux operating system. The display card driving device comprises a drive storage unit, a detection unit, a determination unit, a matching unit and a configuration unit. The drive storage unit is used for storing drives of various display cards. The detection unit is used for uninterruptedly detecting display card information set in a computer with the operating system. The determination unit is used for determining a type of a display card in the computer according to varied display card information detected. The matching unit is used for judging whether at least one display card drive stored in the drive storage unit is matched with the type of the display card determined or not and selecting the display card drive matched with the type of the display card determined from various display card drives stored. The configuration unit is used for configuring and loading the display card corresponding to the varied display card information on the basis of the display card drive selected. By combining drives of a built-in INTEL display card, a plug-in NVIDIA display card and an ATI display card, support of the display card drives for library function is improved.

Description

technical field [0001] The invention relates to an operating system, in particular to a Linux operating system and a graphics card driving device used for graphics card hardware adaptation. Background technique [0002] As the Linux system has been widely used, it has more and more users in the civil, office and development fields. [0003] The graphics card driver for the existing Linux graphical user interface is mainly provided by xorg in two modes: the graphics card driver and the external graphics card driver, wherein xorg is an implementation body developed based on the architecture X window system. The graphics card is between the display and the motherboard, and plays the role of human-computer interaction. The interface between the graphics card and the motherboard is a peripheral component expansion interface (Peripheral Component Interconnection, hereinafter referred to as PCI) slot. The graphics card is responsible for converting the received signal into an ele...
