June 24, 2016 at 12:43 PMJun 24, 2016 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 Rob

June 27, 2016 at 12:48 PMJun 27, 2016 Author 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 X Error of failed request: BadMatch (invalid parameter attributes) Major opcode of failed request: 140 (RANDR) Minor opcode of failed request: 2 (RRSetScreenConfig) Serial number of failed request: 14 Current serial number in output stream: 14 tf@red-brick:~$ Rob
