Ubuntu mate 16 refuses to rotate on odroid C2

i tried to rotate using xorg.conf as seen here: https://unix.stackexchange.com/questions/103460/how-to-change-gnome-default-screen-rotation
Section "Monitor" Identifier "Monitor1" Option "Rotate" "left" EndSection

i even tried xrandr
xrandr -o left
but getting crazy errors

any ideas we can try?

got it working with xorg.conf by adding a single line from https://forum.odroid.com/viewtopic.php?f=136&t=18709&p=168184&hilit=rotate#p168184

Section “Device”
Identifier “Mali FBDEV”
Driver “fbturbo”
Option “fbdev” “/dev/fb0”
Option “Rotate” "CCW"
Option “SwapbuffersWait” “true”
EndSection
