Cambiar brillo en Ubuntu con tarjeta Nvidia

¿Instalas Ubuntu en tu ordenador y no puedes cambiar el brillo? Si tienes una tarjeta gráfica Nvidia aquí tienes la solución:

Primero tenemos que añadir unos parámetros en el kernel así que primero lo abrimos escribiendo lo siguiente en la terminal:
sudo gedit /etc/default/grub

Buscamos la linea que diga GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash” y añadimos “acpi_backlight=vendor” de forma que quede lo siguiente:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_backlight=vendor"

Guardamos y cerramos. Actualizamos:

sudo update-grub

Ahora, si reiniciáis el ordenador podréis cambiar el brillo de la pantalla con el teclado o con el ratón.
