I'm using an imx6slevk board with yocto BSP

I use linuxfb as the display driver and run a qt app (rastor window: prints a message on the lcd console)

I observed that when the app is running the screen doesn't timeout after 10 minutes of staying idle

How can I change this?


I tried modifying /drivers/tty/vt/vt.c file but the screen doesn't turn off 

I also observed that the weston feature is not supported in linuxfb 

does anyone have an idea how to implement this without weston?
