Running an X11 program from another TTY can be useful when you want to run a graphical application on a different virtual terminal. This can be especially helpful if you are experiencing issues with your current desktop environment or if you want to run a program in the background without interrupting your current session. In this article, we will guide you through the process of running an X11 program from another TTY.
Step 1: Switch to the desired TTY
The first step is to switch to the TTY where you want to run the X11 program. You can do this by pressing Ctrl + Alt + F2 (or any other function key from F1 to F6) on your keyboard. This will take you to a new terminal without any graphical interface.
Step 2: Log in to the TTY
Once you are on the new TTY, you will be prompted to log in with your username and password. Enter the credentials and press Enter to proceed.
Step 3: Set the DISPLAY variable
The next step is to set the DISPLAY variable, which tells the X11 program where to display its graphical output. In the terminal, type the following command:
export DISPLAY=:0
This command sets the DISPLAY variable to the default value, which is usually :0. If you are using a different display, you can specify it accordingly. For example, if you want to use display :1, you can set the variable as export DISPLAY=:1.
Step 4: Run the X11 program
Now that you have set the DISPLAY variable, you can run the X11 program. Simply type the command to start the program in the terminal and press Enter. The program should now start and display its graphical interface on the specified display.
Step 5: Switch back to the original TTY
After you have finished running the X11 program, you can switch back to your original TTY by pressing Ctrl + Alt + F1 (or the function key corresponding to your original TTY). This will take you back to your desktop environment or graphical interface.
That's it! You have successfully run an X11 program from another TTY. This method can be particularly useful when you want to run graphical applications in the background or troubleshoot issues with your current desktop environment.
Remember, the steps mentioned above assume that you have already installed the necessary X11 libraries and dependencies on your system. If you encounter any errors or issues while running an X11 program, make sure to check if all the required packages are installed.
