Turn off X screen blanking

Turn off X screen blanking

I am trying to disable screen blanking in X by default.  This bug talks
about doing the same thing but it is not currently completed:
https://bugzilla.yoctoproject.org/show_bug.cgi?id=7278

I am using "dizzy" for compatibility with the meta-amd layer.  I found the
xserver-common recipe in meta-oe and I suppose I could add another patch
like 0015-xserver-common-disable-TCP-connections.patch, but I'd rather do
it using a .bbappend file in another layer.  My question is how I might go
about doing that using a bbappend file?

Thanks,
Bob Kocisko

add something like

/usr/bin/xset -dpms s off s noblank s 0 0 s noexpose

to rc.local or systemd service file whatever you are using.
ensure that X server has initialised fully before running this and ofcource
add xset to your image.

Thank you Khem.  I was thinking that modifying the X command line to do
this would somehow be more 'low-level' and more 'official' than using
xset.  Does anyone know if there is a difference?

I also realized that it would probably work to .bbappend the SRC_FILES
variable with another patch file that tweaks the command line.  I haven't
tried it yet though.
