OpenClaw 技能 screen_cotrol_for_Ubuntu：控制 Ubuntu Xorg 桌面

🖥️ screen_cotrol_for_Ubuntu - Control Ubuntu Xorg Desktop Easily

screen_cotrol_for_Ubuntu is a tool made to help you control the Ubuntu Xorg (X11) desktop environment. It works only with the Xorg display server. If your computer uses Wayland, this program will not function properly.

This application comes as a skill for OpenClaw, designed to work within the Ubuntu desktop environment. It offers simple ways to manage screen-related tasks with straightforward controls. You can use it to adjust screen settings, switch displays, or manage multiple monitors.

This tool is intended for users who want easy desktop control without needing commands or coding knowledge. The app runs on Ubuntu systems that use Xorg and will not work on Wayland sessions.

🖥️ System Requirements

To use screen_cotrol_for_Ubuntu, you need:

Ubuntu desktop with Xorg (X11) display server.
Not compatible with Wayland sessions.
A PC running Ubuntu 18.04 or later versions.
At least 4 GB of RAM.
Basic mouse and keyboard setup.

If you are unsure whether your Ubuntu uses Xorg or Wayland, you can check by opening the terminal and typing:

echo $XDG_SESSION_TYPE

If it returns "x11", your system uses Xorg. If it returns "wayland", this tool will not run correctly.

🚀 Getting Started

Look for the latest version listed at the top of the page. It usually has a version number like v1.0 or v2.0.
Scroll down to the "Assets" section under the latest version.
Download the file that ends with .AppImage or .deb (common Linux package formats). If you see files with .exe for Windows or others, do not download those — this app is for Ubuntu Xorg only.
Save the file to a folder where you can find it later, like your Downloads folder.

⚙️ Install screen_cotrol_for_Ubuntu

After you download the file, follow these instructions to install and start the app.

For `.deb` files:

Open the file manager and find the downloaded .deb file.
Double click the .deb file. This will open the Ubuntu Software Center or a package installer.
Click "Install" in the Software Center to begin the installation. You may need to enter your computer password.
Wait for the installation to finish.
Once done, find the app by searching for "screen_cotrol_for_Ubuntu" in your Applications menu.

For `.AppImage` files:

An AppImage is a portable format that does not require installation.

Open the terminal or file manager and locate the downloaded .AppImage file.
Right-click the file and select "Properties."
Go to the "Permissions" tab and check the box to "Allow executing file as program."
Close the Properties window.
Double-click the AppImage file or run it from the terminal by typing ./filename.AppImage (replace filename with the name of your file).
The app will start automatically.

▶️ Running screen_cotrol_for_Ubuntu

Once installed, you can run screen_cotrol_for_Ubuntu from your Applications menu or by double-clicking the AppImage file.

The app opens a simple window where you can:

Adjust screen brightness and resolution
Switch between multiple monitors
Enable or disable displays
Manage screen rotation

The interface uses clear buttons. Click the options you need to control your desktop screen. No additional setup or command lines are necessary.

If the app shows an error about Wayland, check your session type. You need to be logged into an Xorg session for it to work properly.

🛠️ Troubleshooting Tips

App does not start: Make sure you are running Ubuntu with Xorg, not Wayland. Confirm by typing echo $XDG_SESSION_TYPE in the terminal.
Permissions issues with AppImage: Ensure the executable permission is properly set. Use the terminal command chmod +x filename.AppImage if needed.
Screen options do not work: Verify your system recognizes multiple monitors in Settings -> Displays.
Missing features: This app focuses on basic screen controls. It does not support advanced window management.
