In Linux or UNIX, you can run multiple X sessions (graphical sessions) simultaneously by using different virtual terminals (VTs). Here’s how to do it:
- Press “Ctrl + Alt + F2” (or any other function key from F2 to F7) to switch to the second virtual terminal. This opens a new login prompt.
- Log in with your username and password. This will start a new X session on the second VT.
- Press “Ctrl + Alt + F3” (or any other function key from F2 to F7) to switch to the third virtual terminal. This opens another new login prompt.
- Log in with your username and password again. This will start a third X session on the third VT.
You can switch between the virtual terminals by using the “Ctrl + Alt + Fx” keys, where “x” is the function key number. Each virtual terminal is a separate X session, so you can run different applications and desktop environments on each one.
To exit a virtual terminal and return to the previous one, simply log out of the X session or type “exit” in the terminal. You can also use the “startx” command to start a new X session from within an existing X session. For example:
startx -- :1
This command starts a new X session on display :1 (the default is display :0). You can use different display numbers to start multiple X sessions on different virtual terminals.
By using multiple virtual terminals and X sessions, you can run multiple graphical sessions simultaneously in Linux or UNIX.
