Title: Disable console screen blanking
Post by: tohox on September 30, 2016, 12:00:23 PM

Hi,

I noticed that the console screen goes blank after a few minutes and would like to disable this. Under Raspbian in /etc/kbd/config one could set BLANK_TIME=0 and POWERDOWN_TIME=0 to achieve this. What would the equivalent be under PiCore 8.0?

Thanks,

Not sure for the RPi but one of these usually work for me

Code: [Select]

setterm -blank 0


Code: [Select]

echo -e '\033[9;0]'

Setterm doesn't seem to be available (I assume it is part of util-linux.tcz?) so I'll try echo -e '\033[9;0]'

Must this be entered on the console itself or would entering it from any SSH terminal window or a startup script work as well?

Thanks,

I don't know. I'd add it to  /opt/bootlocal.sh .

Try: xset s noblank

So far echo -e '\033[9;0]' works if entered from the physical console or a startup script but not if entered from an SSH terminal window which is fine for me.

Xset also appears to require the installation of a separate TCE extension as it isn't available to me currently.

Thanks!

@Beerstein, thanks for the suggestion but I assume xset is used with X? My system is currently running headless.

echo -e '\033[9;0]' did the trick though.

thanks,

For the sake of completeness, here is where ESC[9;#] and other codes come from:
