The VNC server will wake up the display if it can. If there's something else hogging the wake-up mechanism, it can't do it. There's probably some other process holding onto the output power management resource that's blocking the VNC server.I found that the problem was, the HDMI display was asleep! Previously establishing a remote connection was automatically waking it up. Not so any more? As long as the display is awake (it automatically goes to sleep after 10 minutes of no activity) the remote connections work. The "gray screen" seen otherwise simply represented exactly what was on the screen. Which rather defeats the concept of Remote Desktop.
