L3.10.53 Xorg xrandr command

Hi Chip experts,

According to the document, xrandr command already supported.

i.MX_6_Graphics_Users_Guide.pdf

https://community.freescale.com/message/520370

So I tried to change --brightness or --gamma of my SabreSD board but nothing changed.

Have those xrandr parameters been supported?

If somebody knows, please let me know. Please see attached log.

Thanks.

Hi torus1000,

Current xrand is supported however there are some features that are not accelerated by GPU, and this is marked as a bug.

Reduced graphic performance with rotated screen (imx6, sabresd)

Hope this helps
