LVDS brightness problem

using 10.1 inch LVDS Capacitive Touch Display 1280x800.

proceeded to bring up the screen using setenv.

The screen is too bright, so I tried setting the backlight, but nothing changed.

setenv vidargs ‘video=mxcfb0:dev=ldb,1280x800M@60,if=RGB666 ldb=sin0 video=mxcfb1:off video=mxcfb2:off video=mxcfb3:off fbmem=32M’

I changed the two settings as below and it became normal.

imx6qdl-apalis.dtsi → fsl,data-width = 24

setenv vidargs → 'video=mxcfb0:dev=ldb,1280x800M@60,if=RGB24 ldb=sin0 video=mxcfb1:off

Hello @rynforce ,

Greetings from ToradexCommunity!!
Could you maybe try to adjust the backlight setting as suggested in this article: https://developer.toradex.com/knowledge-base/backlight-linux#PWM
