We have a LVDS LCD working using the imx_lbd driver, however it insists on turning off about 15 minutes after power-up. Any ideas on how to turn off this "feature" ? I have tried
echo -e '\033[9;0]' > /dev/tty1
echo 0 > /sys/class/graphics/fb0/blank
echo 0 > /sys/class/graphics/fb1/blank
echo 0 > /sys/class/graphics/fb2/blank
echo 0 > /sys/class/graphics/fb3/blank
and that did not help. We are using a i.MX6Q on the Linux 3.0.35-4.1.0 BSP. Gnome is not used
Any help would be appreciated

Hello Otto,
By default, the blank interval of a terminal is 10 minutes and the screen will automatically blank when the terminal has no activity after this interval.
You can goto the file "linux/drivers/tty/vt/vt.c" and change the static global "blankinterval" to 0 and then rebuild the kernel. Alternatively. if your build has added the "util-linux" package, you can use command "setterm -blank 0" to disable this feature.
