# Desactivar o acceso á liña de ordes

To disable command-line access for your desktop user, you need to make configuration changes in a number of different contexts. Bear in mind that the following steps do not remove the desktop user's permissions to access a command line, but rather remove the ways that the desktop user could access the command line.

Set the `org.gnome.desktop.lockdown.disable-command-line` GSettings key, which prevents the user from accessing the terminal or specifying a command line to be executed (the Alt F2 command prompt).

Prevent users from accessing the Alt F2 command prompt.

Disable switching to virtual terminals (VTs) with the Ctrl Alt function key shortcuts by modifying the X server configuration.

Remove Terminal and all other terminal applications from the Activities overview in GNOME Shell. You will also need to prevent the user from installing a new terminal application.

# Desacetiva a liña de ordes

Create a local database for machine-wide settings in /etc/dconf/db/local.d/00-lockdown:

# Especifica a ruta de dconf [org/gnome/desktop/lockdown]

# Desactiva a liña de ordes disable-command-line=true

Override the user’s setting and prevent the user from changing it in /etc/dconf/db/local.d/locks/lockdown:

# List the keys used to configure lockdown /org/gnome/desktop/lockdown/disable-command-line

# Desactivar soltar dun terminal virtual

Users can normally use the Ctrl Alt function key shortcuts (for example, Ctrl Alt F2) to switch from the GNOME desktop to a virtual terminal.

If the computer is running the X Window System, you can disable access to all virtual terminals by adding a `DontVTSwitch` option to the `Serverflags` section in an X configuration file in the /etc/X11/xorg.conf.d/ directory.

Create or edit an X configuration file in /etc/X11/xorg.conf.d/. For example, /etc/X11/xorg.conf.d/10-xorg.conf:

## /etc/X11/xorg.conf.d/10-xorg.conf

Section "Serverflags"

Option "DontVTSwitch" "yes"
