      Hey guys!

      I’ve a problem with my display, where it stays dark after I enable the HDMI output via commandline like this:
      First I disable the output with /opt/vc/nin/tvservice -o and the display goes in standby after some seconds like it should be.
      But when I want to activate it again /opt/vc/nin/tvservice -p the display wakes up and gets a bit brighter but stays blank/dark after that.

      Does anyone know that problem and may have a solution for this?
