OS: Poky ( Yocto Project Reference Distro ) 1.6.2
Board: i MAX6QI am trying to adjust the display contrast by this command:
xrandr --output output_name --gamma 1:1:1
Result as fellow:
Desktop Ubuntu : work fine Yocto : not work
BSPs older than the 3.10.17-1.0.0 release do not support xrandr. I would recommend migrating to the newest BSP possible.
These newer BSP releases do include some documentation regarding the use of the Xserver video driver so you may want to review this documentation as well.
Thanks for your answer.
the BSP version is imx-3.10.53-1.1.0_ga, and other xrandr command has properly worked, like size,only except xrandr gamma, typed the command into console and nothing happened.
