[0019] In the description of the present invention, it should be noted that, unless otherwise clearly defined and limited, the terms "installed", "connected", "connected" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood through specific situations.

[0020] In the description of the present invention, it should be further noted that the terms "first", "second", etc. are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first", "second", etc. may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, the meaning of "a plurality" is two or more.

[0021] The application scenarios of a display function management method, device, equipment, and product of a system device disclosed by the present invention are as Figure 1 shown. In the prior art, it is impossible to use a remote desktop environment on a server or an embedded device without a display device, which brings great inconvenience to the full use of the server or the embedded device without a display device, and affects the flexible use and deployment of the server or the embedded device without a display device. A display function management method, device, equipment, and product disclosed by the present invention includes: determining whether a graphics card is installed; after successfully loading the corresponding driver program, starting the desktop environment program of the system device; starting the remote shared desktop service program to share the desktop display output to the remote shared client; the present invention can automatically implement the remote desktop function directly on a system device without a display function or on a system device with a display device by default, and has the characteristics of reliable performance, good adaptability, and wide application range.

[0022] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0023] As Figures 2 to 3 shown, a display function management method of a system device includes: Step S201, determining whether a graphics card is installed in the system device. If a graphics card is installed in the system device, then loading the graphics card driver corresponding to the graphics card; if no graphics card is installed in the system device, then loading the virtual display driver. Exemplarily, by starting the display manager lightdm and starting the Xorg program, when the display manager lightdm starts the desktop environment, it will scan the configuration file 50-xserver-command.conf in the / usr / share / lightdm / lightdm.conf.d directory regarding how to start the Xorg program. The configuration file 50-xserver-command.conf describes how the display manager lightdm starts the Xorg program. The configuration file 50-xserver-command.conf represents that the Xorg service is started in the way of executing "X-core", where X is the encapsulation of the corresponding Xorg program startup.

[0024] In this embodiment, if a graphics card is installed in the system device, the Xorg program will load the corresponding DDX driver (DeviceDependentX, DDX). Step S202, after successfully loading the graphics card driver program or the virtual display driver program, start the desktop environment program of the system device. In this embodiment, loading the virtual display driver program includes: first installing the virtual display driver program package, and then loading the virtual display driver program.

[0025] Step S203, the desktop environment program of the system device starts the remote shared desktop service program, and the remote shared desktop service program shares the desktop display output of the graphics card driver program or the desktop display output of the virtual display driver program to the remote shared client.

[0026] Exemplarily, the desktop environment program of the system device is the ukui desktop environment of the Kylin system device, and the display manager lightdm will read the configuration file / usr / share / xsessions / ukui.desktop of the Kylin desktop environment to start the desktop environment.

[0027] The display manager lightdm starts the ukui-session program in Exec=ukui-session in ukui.deskop. The ukui-session program is a program set that contains a group of programs required for starting the desktop environment. The ukui-session program will start the corresponding components required for the ukui desktop environment in / etc / xdg / autostart according to the actual definition, and most of these components appear in the form of xxx.desktop.

[0028] Exemplarily, the remote shared desktop service program is the remote display desktop service program Vino, and the startup information of the remote display desktop service program Vino is in vino-server.desktop. This embodiment provides a method for implementing remote shared desktop service on a system device without a display function, which can meet the requirement that in some special scenarios, even without a display function or when the display driver cannot be normally loaded, the remote desktop function can still be used for remote login operations.

[0029] Based on the previous embodiment, in another embodiment of the present invention, as Figure 2As shown, in step S201, it is determined whether a graphics card is installed in the system device, including: if there is either a direct rendering device node or a frame buffer device node in the system device, then a graphics card is installed in the system device; if neither a direct rendering device node nor a frame buffer device node exists in the system device, then no graphics card is installed in the system device.

[0030] Exemplarily, during the startup process of the Xorg program, a function is added to determine whether a graphics card is installed in the system device. The direct rendering device node is represented as the node / dev / dri / *, and the frame buffer device node is represented as the node / dev / fb*. If neither the node / dev / dri / * nor the node / dev / fb* exists, then there is no graphics card device in the system device or the graphics card driver is not loaded properly.

[0031] The node / dev / dri / * is used to store the pixel data displayed on the monitor, and the node / dev / fb* is used to directly operate the video memory to achieve control of the screen.

[0032] Since not all display devices can support the display rendering of the corresponding DRI interface, it is necessary to simultaneously determine whether the node / dev / dri / * and the node / dev / fb* exist. And since multiple nodes may be visible if there are multiple graphics cards, for example, in the case of dual graphics cards, there are nodes / dev / fb0, / dev / fb1, / dev / dri / card0, and / dev / dri / card1. Use the access function to determine whether there is a direct rendering device node or a frame buffer device node in the system device.

[0033] Exemplarily, for the access function (" / dev / fb0", F_OK), if the return value is 0, it means the node exists; if it is non - zero, it means the node does not exist.

[0034] In the previous embodiment, as Figure 2 shown, step S201 also includes: reading a preset configuration file. If the virtual display function is not enabled in the configuration file, then give up loading the virtual display driver program.

[0035] Exemplarily, use the Xorg program to read the configuration file to see if the virtual display function is configured.

[0036] Further, if the virtual display function is configured, set XORGCONF through the system device standard function setenv in the Xorg program code. For example, setenv("XORGCONF"," / usr / share / X11 / custom / dummy.conf",1); that is, set the XORGCONF variable through setenv to load the configuration file / usr / share / X11 / custom / dummy.conf customized by the specific dummy driver. Here, dummy is the virtual display driver program. Further, the Xorg program will load dummy according to the Driver "dummy" node information in dummy.conf. To load dummy, the corresponding virtual display driver package xserver-xorg-video-dummy needs to be installed first. You can use sudo dpkg -i xserver-xorg-video-dummy to install the corresponding dummy. The Xorg program will search the corresponding / usr / lib / xorg / modules / drivers / directory to match the corresponding dummy_drv.so library to load the corresponding driver.

[0037] In the previous embodiment, the remote sharing client sets the IP address through the input remote sharing desktop service program to establish a network connection between the remote sharing client and the remote sharing desktop service program.
