Hi,

Carlos Soto uses a Karo mx25 and he noticed that the LCD only works if we do:

echo 1 > /sys/class/graphics/fb0/blank
echo 0 > /sys/class/graphics/fb0/blank

I can confirm the same on mx25pdk running 3.19 [1], but I could not
understand why the display does not start turned on by default.

Any ideas?

Thanks,

Fabio Estevam
