While working on gswitcheroo I needed a reliable way to determine if a monitor get’s connected to the HDMI port of the discrete card. But monitoring the HDMI port when the corresponding discrete card is powered off, doesn’t seem to work.\ A temporary solution is to power on the discrete card once and again, to see if a some monitor got connected. airlied point out, that maybe the integrated card is able to detect connected monitors. But in the first trial it didn’t really work.\ \ What also didn’t work, was monitoring status changes of the discrete (radeon) card using udev (using udevadm monitor).  Time for more investigations.
