screen rotation

tiras

can i ask the advanced users how to rotate the screen.
I tried third party applications with no luck.

also tried a tv which has portrait mode but it didnt help either.

editing build.prop line: "ro.sf.hwrotation=270″. didnt do the trick.


what else i could try?

spirit

I was able to get screen rotation working in linux, but not in android. I think the problem is that RandR is not supported by the default drivers, but since hardware acceleration isn't working yet in linux anyway, you can just rotate the framebuffer device:

/etc/X11/xorg.conf

1. Section "Device"
   
2.         Identifier "default"
   
3.         Driver "fbdev"
   
4.         Option "Rotate" "UD"
   
5. EndSection

Copy code

This rotates by 180 degrees, but replace 'UD' with 'CCW' or 'CW' if you want to rotate it by 90 or 270.

I tested this with OrangePi One using loboris' image OrangePI-PC_Ubuntu_Vivid_Mate.img. I'm afraid I can't help with android.
