Instalé Arch en mi computadora portátil, pero no creo que este problema sea específico para Arch. El único problema en este momento es que no se detecta la pantalla conectada al puerto HDMI. Por ejemplo, desde el centro de control de gnome, el applet de pantalla luego 'detectar' solo detecta la pantalla de la computadora portátil, a pesar de que hay un segundo monitor conectado a la computadora portátil a través del puerto HDMI. Sospecho que el problema es que xrandr no detecta el monitor conectado al puerto HDMI. ¿Cómo puedo arreglar esto?
