Im using Linaro Raring Server for Cubieboard A20 from here:

www.cubieforums.com/index.php?topic=807.0

After about 10 minutes, the screen goes to black, even I'm using keyboard or mouse, so seems not be a screensaver to me, since not idle. Nothing I can do brings the screen back again, only a reboot. My system still alive (my TV shows signal is active).

I'm not using GUI, so answer in terminal commands.

I don't use GUI, but have a X11, because xbmc is installed on system. At startup, xbmc starts without login.

Steps I've done:

1) Start system and XBMC. Auto login (root). Black screen after 10 min even using keyboard/mouse.

2) Start without XBMC (and GUI). Auto login (root). Black screen after 10 min even using keyboard/mouse.

Tried this https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1072531

and this How to stop screen going black after 10 min

I don't have xset and can't find where xorg.conf is.

There is a X11 in init folder. XBMC is using framebuffer.

I figured out by adding consoleblank = 0 in /boot/uEnv.txt file. I think this file is the same as kernel commands in boot process.

extraargs = disp.screen0_output_mode=1280x720p60 consoleblank=0

Try setting the option "LOCK_SCREEN" to false in /etc/default/acpi-support

Another place to try is via grub, edit /etc/default/grub, change GRUB_CMDLINE_LINUX="" to GRUB_CMDLINE_LINUX="acpi_osi=Linux acpi_backlight=vendor"
