Graphics card display method and system in UEFI mode and related components thereof

Abstract

The invention discloses a graphics card display method, a graphics card display system and a graphics card display device in a UEFI mode, and a readable storage medium. The graphics card display method comprises the steps of: judging whether a graphics card priority in BIOS setting options is an external graphics card being preferred; if so, detecting whether the external graphics card is insertedinto an external card slot or not; when the external graphics card is inserted into the external card slot, determining that the external graphics card is a target graphics card, and enabling an onboard graphics card to be in a closed state; when no external graphics card exists in the external card slot, determining that the onboard graphics card is a target graphics card, and enabling the onboard graphics card to be in an open state; and if not, determining that the onboard graphics card is the target graphics card, and enabling the onboard graphics card to be in an open state. The graphicscard display method determines the unique target graphics card according to whether different graphics card priorities and the external graphics card exist or not, and completes the subsequent setting of the target graphics card, so that the graphics card display system takes the target graphics card as the main graphics card, the problem that the external graphics card cannot enter a Linux system graphical interface in the original UEFI mode is solved, and the application flexibility of the graphics card in the mode is improved.

Description

Technical field [0001] The invention relates to the field of server hardware settings, and in particular to a UEFI mode graphics card display method, system and related components. Background technique [0002] Usually, the server motherboard has an onboard graphics card, which can output images without an external graphics card. When the server is plugged into an external graphics card and tries to use the external graphics card as a display output, there may be a problem that the external graphics card cannot enter the Linux graphical interface. This is because only in legacy mode can the onboard graphics card and external graphics card be set to give priority to output, and in UEFI (Unified Extensible Firmware Interface) mode, the onboard graphics card and the efi driver of the external graphics card will Exist at the same time. Two efi drivers load GOP (Graphics Output Protocol) at the same time. GRUB (Grand Unified Bootloader) cannot determine which graphics card the GOP be...

When the server is plugged into an external graphics card and tries to use the external graphics card as a display output, there may be a problem that the external graphics card cannot enter the Linux graphical interface

This is because only in legacy mode can you set the priority output between the onboard graphics card and the external graphics card, and in UEFI (Unified Extensible Firmware Interface, unified extensible firmware interface) mode, the efi driver of the onboard graphics card and the external graphics card will be At the same time, two efi drivers load GOP (Graphics Output Protocol, graphics output protocol) at the same time, GRUB (Grand Unified Bootloader, bootloader) cannot determine which graphics card GOP belongs to, and will only load the graphics card of the first GOP, and also That is, the onboard graphics card is used as the main graphics card, and the external graphics card cannot display the graphical interface.
