39DRM drivers also add options to enable or disable outputs:

41'e' will force the display to be enabled, i.e. it will override the detection
42if a display is connected. 'D' will force the display to be enabled and use
43digital output. This is useful for outputs that have both analog and digital
44signals (e.g. HDMI and DVI-I). For other outputs it behaves like 'e'. If 'd'
45is specified the output is disabled.
