Any device used in the method of the first embodiment of the present invention falls within the scope of protection of the present invention.

[0047] Embodiment Three

[0048] Based on the Linux window system, this embodiment provides a method for transplanting a cloud desktop to the user's machine for localization. This method is implemented through the following components: the cloud computer permission authentication service running at the backend, the cloud computer client running on the user terminal, the cloud computer application store, the cloud disk browser, the cloud computer resource manager, as well as the remote server, XServer graphics service, and window management program running on the cloud computer. The specific implementation steps are as follows:

[0049] Step 1: Connection establishment

[0050] The user opens the cloud computer client and establishes a network connection with the remote server inside the cloud computer through the cloud computer permission authentication service.

[0051] Step 2: Application download

[0052] The user opens the cloud computer application store through the cloud computer client and downloads the application and its related information (including application icons, application names, etc.) to the cloud disk of the cloud computer.

[0053] Step 3: Application installation

[0054] The user installs the application in the application store. At this time, the application store sends the "install application" instruction to the remote server inside the cloud computer through the cloud computer client. After receiving the "install application" instruction, the remote server reads the application installation package in the cloud disk and completes the installation, and then returns the installation result to the user client program.

[0055] Step 4: Installation result processing

[0056] The client program reads the returned result. If the installation is successful, it writes the information of the installed application into the "application list" configuration file and creates a cloud application icon on the local desktop.

[0057] Step 5: Application startup

[0058] The user clicks the cloud application icon on the local desktop, triggering the cloud computer client program to send a "start application instruction" to the remote server inside the cloud computer. After receiving the instruction, the remote server starts the application.

[0059] Step 6: Window status monitoring and feedback

[0060] The window manager inside the cloud computer monitors window events (including window creation, destruction, status changes, etc.) and sends these events to the cloud computer client through a remote server. The client modifies the display status of the cloud application icons in the local desktop navigation bar according to the received event information, enabling users to understand the current running status of the cloud applications through the icon status in the navigation bar.

[0061] Step Seven: Screen Thumbnail Display

[0062] When the user's mouse hovers over the cloud application icon on the local desktop, the cloud computer client sends a command to the remote server to request cloud computer screen thumbnail information. The remote server sends the current cloud computer screen information to the client in real time, and the client then displays the cloud computer screen thumbnail to the right of the mouse in real time for the user to view the running screen of the application.

[0063] Step Eight: Remote Screen Display

[0064] When the user needs to remotely operate a cloud application, they can click a button on the cloud computer client to send a "display cloud computer screen" command to the remote server. The remote server encodes the real-time screen information and sends it to the client, and the client creates a window and displays the cloud computer screen.

[0065] Step Nine: Keyboard and Mouse Control

[0066] When the user operates the cloud computer screen displayed in Step Eight through the keyboard and mouse, the cloud computer client passes the keyboard and mouse input events to the remote server of the cloud computer, and the remote server responds to the local keyboard and mouse operations.

[0067] Step Ten: Window Status Update

[0068] When the user minimizes, maximizes, or closes the window of the cloud computer screen, the window manager inside the cloud computer passes the window status change event to the cloud computer client through the remote server, and the client modifies the display status of the cloud application icons in the navigation bar according to the event.

[0069] Step Eleven: Application Uninstallation

[0070] When the user uninstalls an application in the cloud computer application store, the application store sends an "uninstall application" command to the remote server through the cloud computer client. After receiving the command, the remote server closes the application and completes the uninstallation, and returns the result to the cloud computer client.

[0071] Step Twelve: Uninstallation Result Processing

[0072] After the cloud computer client receives the "application uninstall" reply, it deletes the cloud application icon on the local desktop.

[0073] Through the above steps, this embodiment realizes the localization operation of the cloud desktop, providing users with an efficient and convenient cloud computer usage experience.

[0074] The technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0075] Through this embodiment, the cloud computer no longer needs to create a desktop. By only cooperating with the window management program through XServer to manage the desktop application programs, the cloud storage and computing resources of the cloud computer can be significantly reduced; directly create cloud application icons on the local screen of the user for cloud application operations, and a cloud desktop can be created locally for reference operations. Users can manage cloud computer desktop applications like managing local desktop applications, and the experience is better than that of traditional cloud computer cloud desktop systems.
