Cannot support Xrandr rotation under Allwinner A33 (AccelMethod = CPU) #46
Comments
I cannot use Rotate=UD now, because it will disable XRANDR, but my window manager (Mutter) do not support X Server without XRANDR. |
Changing the display output configuration at runtime via XRANDR is not supported at the moment. Not that it can't be done, but this:
I don't know if the A33 kernel from Allwinner has the disp ioctl API, which is fully backwards compatible with A10/A13/A20. For example, do you get Xv overlay working in mplayer? Can you paste your current /var/log/Xorg.0.log somewhere (via gist)? |
At least it do not have g2d, so AccelMethod is set to CPU. And as I know, sunxi disp interface do not support rotation(otherwise I won't refer to X.Org Driver to find a way to rotate the display ---- Siarhei Siamashka编写 ---- Changing the display output configuration at runtime via XRANDR is not supported at the moment.

xrandr --output default --rotate inverted returns "xrandr: output default cannot use rotation "inverted" reflection "none""
How can I fix it?
