Ubuntu GUI Switch: Startx & Install Guide

In Ubuntu, you can switch to the graphical interface using the following method:

1. If you are already in the command line interface (without a graphical interface), you can use the startx command to launch the graphical interface. This command will attempt to start the default window manager.
2. If the startx command is invalid or if a graphical interface is not installed, you can try installing and starting a window manager. Common window managers include GNOME, KDE, Xfce, and others. You can use the following command to install the GNOME desktop environment:
3. Update your system using the following command:

   sudo apt-get update

   Install the Ubuntu desktop using the following command:

   sudo apt-get install ubuntu-desktop

4. After the installation is complete, restart the computer. At the login screen, select GNOME (or another window manager you installed), then enter your username and password to access the graphical interface.
5. If you have already installed the graphical user interface but default to the command line interface, you can try modifying the default run level. Use the following command to open the configuration file:
6. Edit the “/etc/default/grub” file using the sudo nano command.
7. Locate a line of code similar to GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash” and modify it to GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash text”. Save and exit the file. Then update the GRUB configuration using the following command.
8. Update the grub using sudo.
9. After restarting the computer, it should directly enter the graphical interface.

Please note that these methods may vary depending on the version of Ubuntu. If the above methods do not work, you can seek more help in Ubuntu’s official documentation or related forums.
