HDMI Screen Rotation

[Rob]

Im using a 5" HDMI Adafruit screen with the red brick, cant figure how to get it to rotate 90 Degrees. xrandr commands return 'Can't open display'

 

Thanks

From where did you ran xrandr? Maybe you need to specify DISPLAY=:0?

 

DISPLAY=:0 xrandr

Thanks - that gives some improvement, but now i get:

 

tf@red-brick:~$ DISPLAY=:0 xrandr -q
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 800 x 480, current 800 x 480, maximum 800 x 480
default connected 800x480+0+0 0mm x 0mm
   800x480       66.00*
tf@red-brick:~$ DISPLAY=:0 xrandr -o right

I'm afraid that you're out of luck. From the xrandr output its seems that the RED Brick video driver doesn't support rotation, sorry
