How to rotate the screen 180 degrees
Hope someone can help. I have a rasplex hooked up to a Dell M100 projector on the ceiling, which unfortunately does not have a rotate display mode (it's not really designed for that!), so everything is upside down!
Previously, it's not been a problem with windows as rotate is a matter of clicking a few options.
How can I get the Rasplex Pi to rotate the display output?
