OpenFDE is a new Linux desktop environment design exploration project. Similar to KDE and GNOME, it aims to provide a cohesive Linux desktop experience from login to running applications. However, what sets OpenFDE apart is its graphical component based on AOSP (Android Open Source Project), which brings a richer ecosystem of applications and games to Linux. It offers a consistent user experience with Android and Linux applications and introduces a unified and innovative approach to Linux desktop application development, providing a fresh perspective on using Linux desktop environments.

4.1.2 Logout​

Clicking on the Start menu, then clicking on the power button icon in the top right corner will bring up three buttons in sequence: Shutdown, Restart, and Logout. Clicking on the Logout button will allow you to exit to the login screen.

4.2 Configure Input Method​

OpenFDE comes with the default input method of 'iFlytek Voice Input Method'. To quickly open the iFlytek Voice Input Method, locate it in the Start menu. Selecting the iFlytek Voice Input Method option allows you to enable it and agree to the summary of privacy terms. You can configure input methods, keyboard layouts, and skin fonts according to your preferences.

A tip: If you encounter a problem similar to the input box in the figure below that covers the text content in the process of using the iFlytek Voice Input Method, you can hover the mouse over the input method prompt word box, and then press and hold the left and right mouse buttons at the same time, so that you can drag the input method prompt word box to other positions.

Furthermore, during usage, you may have already finished typing, but the predictive text box of the input method still appears, as shown in the image below:

For this situation, it is because the predictive text feature of the Xunfei input method is enabled. It is recommended to disable the predictive text feature of the Xunfei input method.

OpenFDE shares the network directly with the external system (Kylin/UOS/Ubuntu). After logging into the OpenFDE desktop environment, locate the "Settings" icon in the start menu or on the desktop and navigate to "Settings - Network"
