Note that 'xrandr --verbose' will trigger a reprobe of the devices, papering over any missed probe following hotplug. I would suggest preceding with 'xrandr --current --verbose'. If all you are doing is checking status, you need to 'echo detect > status' to trigger a reprobe after hotplug. -Chris _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
