Ah, found it: $ ls /sys/class/drm/card0 card0-DVI-D-1 card0-LVDS-1 dev power uevent card0-HDMI Type A-1 card0-VGA-1 device subsystem $ cat /sys/class/drm/card0/card0-LVDS-1/status connected $ cat /sys/class/drm/card0/card0-LVDS-1/enabled enabled $ cat /sys/class/drm/card0/card0-LVDS-1/modes 1680x1050 1400x1050 1280x1024 1440x900 1280x960 1280x854 1280x800 1280x720 1152x768 1024x768 800x600 848x480 720x480 640x480 -- Pasi
