i cant switch tty with keyboard shortcuts but can switch with chvt commond

If you are unable to switch TTY (virtual terminal) using keyboard shortcuts, but can switch using the chvt command, it is possible that the keyboard shortcuts are not configured correctly or are disabled.

To fix this, you can try the following steps:

1. Check keyboard shortcuts:

   • Open the terminal and run the stty -a command to display the current settings of the terminal.
   • Look for the entries related to switching TTY using keyboard shortcuts. They might be defined as ^X (where X is a number) or ^X^Y (where X and Y are numbers).
   • If the shortcuts are not defined or are disabled, you need to configure or enable them.

2. Configure keyboard shortcuts:

   • Open your shell configuration file (e.g., ~/.bashrc, ~/.zshrc).
   • Add the following lines to define the keyboard shortcuts:

     bind '"\e[1;5A":chvt 1'  # Ctrl+Alt+F1
     bind '"\e[1;5B":chvt 2'  # Ctrl+Alt+F2
     bind '"\e[1;5C":chvt 3'  # Ctrl+Alt+F3
     bind '"\e[1;5D":chvt 4'  # Ctrl+Alt+F4
     

   • Save the file and reload the shell configuration (source ~/.bashrc or source ~/.zshrc).

3. Enable keyboard shortcuts:

   • Some desktop environments or window managers might have their own keyboard shortcut settings. Check the settings for your desktop environment and ensure the shortcuts for switching TTY are enabled.

4. Test the keyboard shortcuts:

   • Press the configured keyboard shortcut (e.g., Ctrl+Alt+F1) to switch to the corresponding TTY. Repeat for other shortcuts.

If the above steps don't work, it is possible that there might be other system-specific configurations or issues causing the problem. In such cases, it could be helpful to provide more details about your specific setup or seek assistance from a relevant technical forum or support channel
