A search has found the X11 “xrandr” command present on the Rasbian box I’ve got handy.
Problem is I’ve no spare cable that fits (it’s a Zero) at the mo so cannot try it!
A quick read on the man page shows:
-o, --orientation rotation
This specifies the orientation of the screen, and can be one of normal, inverted, left or right.
Anyone got a screen handy? No idea if the works, releases the Pi magic smoke or melts the monitor
Thanks to 6by9 for prompting the X11 search!
Need Pi spray - these things are breeding in my house...
