Fig. 3 shows a flowchart of a virtual screen generation method 300 according to an exemplary embodiment of the present invention. The virtual screen generating method 300 of the present invention is suitable for being executed in a computing device 200, wherein an operating system 220 runs in the computing device 200, and the operating system 220 comprises a kernel 123 and a display server 121. Computing device 200 is also connected in communicative connection with a client, facilitating remote operation of computing device 200 by a user at the client. As shown in fig. 3, the virtual screen generating method 300 begins with step S310 of determining whether a display device is connected to the computing device 200.
The computing device 200 determines whether the hardware information can be read through the display data interface of the kernel 123, and if the hardware information can be read, the computing device 200 is connected to the display device 131, and displays a screen in the display device 131 normally according to the hardware information. The display data interface of the kernel 123 is used to transmit display data to a connected hardware device and read hardware information of the display device 131. When the display device 131 is connected to the computer, the computing device 200 can read the hardware information. If the hardware information cannot be read, it is determined that the computing device 200 is not connected with a display device.
FIG. 4 illustrates a prior art non-display connected desktop according to an exemplary embodiment of the present invention. As shown in fig. 4, when the display is not connected, and the desktop is remotely displayed at the client, not only the desktop cannot be completely displayed, but also the operation bar at the bottom of the desktop cannot be displayed, the resolution of the application icon is not normal, and the user cannot operate the computer according to such a display interface. Thus, the present invention builds a virtual screen in which desktop and application icons are displayed, thereby enabling the computing device 200 to be operated at the client according to the virtual screen.
If the computing equipment is connected with the display equipment, when a remote operation request of the client is received, the screen displayed in the display equipment is directly sent to the client.
Subsequently, step S320 is executed, and if no display device is connected, the virtual screen driver is constructed and loaded through the display server 121. The hardware information includes a device resolution for the operating system 220 to draw a screen according to the device resolution. When the virtual screen driver is constructed and loaded, the display server 121 sets the resolution of the virtual screen, which is the resolution of the virtual screen to be constructed, and then sets the resolution of the virtual screen as the resolution of the virtual device to construct the virtual hardware information provided by the virtual screen driver. The virtual screen driver is then constructed from the virtual hardware information and loaded in the driver module 122. The virtual screen driver provides virtual hardware information to the operating system 220, including virtual device resolution. The operating system 220 is viewed as having access to a virtual display device based on the virtual screen driver, capable of displaying a virtual screen having virtual hardware information. The operating system 220 determines the resolution of the virtual screen as the virtual screen resolution according to the virtual device resolution of the virtual hardware information. The invention does not limit the specific value of the resolution of the virtual screen.
Subsequently, step S330 is executed to create a virtual desktop according to the virtual screen driver. And when the virtual desktop is drawn, acquiring virtual hardware information driven by the virtual screen, and taking the resolution of the virtual screen as the resolution of the virtual desktop to draw the virtual desktop. Specifically, the original desktop background picture is adjusted according to the resolution of the virtual screen and displayed; and then, placing components such as an operation bar and the like under the background of the desktop to obtain the virtual desktop.
Subsequently, step S340 is executed to draw icons of one or more applications on the virtual desktop through the kernel 123, so as to obtain a virtual screen. When the icon of the application is drawn, one or more applications needing to draw the application icon in the virtual desktop are determined through the kernel 123, and then the icon file corresponding to the application is obtained from the installation directory of each application to obtain one or more icon files. And finally, arranging one or more icon files in the virtual desktop according to the resolution of the virtual screen so as to draw the virtual desktop. Since the application icons exist in the desktop in the form of icon connections, the operating system 220 does not store the icon files itself, and therefore the icon files need to be obtained from the installation directory, modified to a size suitable for the resolution of the virtual screen, and arranged in the virtual desktop.
Subsequently, step S350 is performed, and when the user at the client wants to remotely operate the computing device 200, the client transmits a remote operation request to the computing device 200. When the computing device 200 receives a remote operation request of the client, the virtual screen is transmitted to the client so that the client operates the computing device 200 according to the virtual screen. Fig. 5 illustrates a schematic diagram of a drawn virtual screen according to an exemplary embodiment of the present invention. As shown in fig. 5, the drawn virtual screen can normally display the desktop and the application thereof, which is convenient for the user at the remote client to operate.
According to an exemplary embodiment of the present invention, when the virtual desktop is built, it is determined that the computing device 200 accesses the display device 131 through the kernel 123, the virtual screen driver is uninstalled in the driver module 122, so that the display device driver corresponding to the display device 131 is loaded in the driver module 122. Further, a screen is drawn according to hardware information of the display device driver to display the screen in the display device 131. Specifically, the desktop and the application are redrawn according to the screen resolution in the hardware information, thereby obtaining a screen suitable for the screen resolution of the display device 131. The invention can monitor whether the hardware equipment is accessed, and seamlessly switches the content to be displayed into the physical screen for displaying.
Fig. 6 illustrates a schematic view showing a virtual screen on a display device when the display device is accessed according to an exemplary embodiment of the present invention. As shown in fig. 6, when the computing device 200 is not connected to a display device, the virtual screen driver lockscreen drv.so is constructed and loaded, and the virtual screen resolution is used as the resolution of the virtual desktop according to the virtual hardware information of the virtual screen driver lockscreen drv.so as to draw the virtual desktop. When it is determined through the kernel 123 that the computing device 200 accesses the display device 131, the virtual screen driver lockscreen drv.so is unloaded, the display device driver amdgpu _ drv.so corresponding to the display device 131 is loaded, and the display device driver amdgpu _ drv.so draws and displays a screen in the display device 131.
According to one embodiment of the invention, when the client is disconnected from the computing device and then re-accessed, the virtual screen previously drawn for the client is sent to the client.
According to one embodiment of the invention, the computing device 200 also receives a resolution adjustment request of the client, the resolution adjustment request including a target resolution. When the virtual screen displayed on the client is too large or too small due to inappropriate resolution of the virtual screen, the client can adjust the resolution of the virtual screen, and the target resolution is the appropriate resolution. And then adjusting the virtual equipment resolution of the virtual hardware information in the virtual screen driver to the target resolution so as to redraw the virtual screen by using the target resolution according to the virtual screen driver, and sending the redrawn virtual screen to the client.
The client receives a remote operation of the client based on the virtual screen when operating the computing device 200 according to the virtual screen. The remote operations are operations on the virtual screen, the computing apparatus 200 regards these remote operations as operations on the computing apparatus 200, performs the remote operations, and displays a procedure and a result of performing the remote operations in the virtual screen. And finally, sending the virtual screen on which the process and the result of executing the remote operation are displayed to the client so that the client synchronously displays the process and the result of executing the remote operation by the computing equipment 200, and a user at the client can know the operation condition of the computing equipment 200 in real time according to the displayed process and the displayed result of the remote operation.
The virtual screen generating method in the invention is suitable for being executed in computing equipment, the computing equipment is in communication connection with a client, an operating system runs in the computing equipment, the operating system comprises a kernel and a display server, and the virtual screen generating method comprises the following steps: when a remote operation request of a client is received, determining whether a display device is connected to a computing device; if the display device is not connected, a virtual screen driver is constructed and loaded through the display server, so that a virtual desktop is drawn according to the virtual screen driver, one or more application icons are drawn on the virtual desktop through the kernel to obtain a virtual screen, and the virtual screen is sent to the client so that the client can operate the computing device according to the virtual screen. According to the invention, by constructing the virtual screen drive, the virtual screen comprising the virtual desktop and one or more application icons can be drawn normally, so that a remote client can also operate the computing equipment normally when the display equipment is not connected.
