Hello, While I was discussing the laptop lid/dock issues with Fedora people this issue was brought up. How do you determine if a display is actually powered on or not? Scenario: - Laptop in a docking station, lid open, so internal LVDS enabled. - External DVI display connected, but powered off. So in this case the external display shouldn't be used, since it's off. What happens is this: # cat /sys/class/drm/card0-DVI-D-1/status connected # cat /sys/class/drm/card0-DVI-D-1/enabled enabled # cat /sys/class/drm/card0-DVI-D-1/modes 1920x1080 1600x1200 1680x1050 1280x1024 1440x900 1280x960 1280x800 1024x768 800x600 800x600 640x480 So it *looks* like it's enabled and active, but actually it's powered off. Is there a method to determine the actual state? That is pretty important information for the daemon/tool/script implementing the "policy" of which outputs to enable/disable.. Thanks! -- Pasi _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
