INFOS:
Armbian Bionic mainline kernel 4.19.20

System: OrangePi Pc
Monitor, full HD (1920*1080), over HDMI.

 

SOLUTION, ROTATE SCREEN:
My rotation Settings that i try:
1. xrandr (not permanently, only for this session)
2. echo n   > /sys/class/graphics/fbcon/rotate_all
n=0,1,2,3  (permanently solution)
See: http://linux-sunxi.org/Display  <-Point:Rotation

 

PROBLEM:
Screen rotation problem:
On every boot the rotation is correctly applied BUT:
Turn Monitor off an then on again, the rotation is NOT applied. 

 

PROBLEM SINCE :
Quarterly update cycle, until november 2018 everything works fine and i did not have this problem.

 

QUESTION:
Is this still the right way rotate the screen, or is there a different/new way.
Whats happend, that the Screen is not rotated after switching on again, how to solve it?

Try this:

/etc/X11/xorg.conf.d/01-armbian-defaults.conf
Section "Monitor"
        Identifier "HDMI-1"
        Option "Rotate" "normal"
EndSection

 

normal(0)/right(90)/inverted(180)/left(270)

Hey thanks,

I added the rotation option to the X11 config but the problem still exists...
