Title: power off lcd display
Post by: Kj4bnh on August 04, 2014, 01:56:29 AM

Why does this code not work?
sudo sh -c 'echo -e "\33[14;10]" >dev/console'
If I change the 14 to 9 this activates the screen saver but the 14 does not turn the back light off.  Any hints?  Thanks Jim

Hi Kj4bnh
How about:

Code: [Select]

xset dpms force offI think  xset  is part of base. If not, you'll need to install  Xlibs.tcz.

Then you did not load Xlibs.

Hi Kj4bnh
Also, in your original post, you meant  /dev/console  not  dev/console , right?

You do realize you set it to wait for 10 minutes before powering down. Did you wait that long?

Hi Rich, Yes I meant >/dev/console, typos.  And yes to waiting ten minutes.
I hope that I/we can resolve this issue so can use Core to replace another live-cd that I am using now.  I believe this is the final hurdle.  Rock on, Jim

Hi Kj4bnh
I suggest you install the  Xlibs.tcz  extension and then try the command in my original response again.

Hi, loaded Xlibs and getting "unable to open display" when using xset dpms force off.  No joy.

Xset works on your X display.  Aparently you are not running X.

I have migrated to Tiny Core 5.3, screen turns off like I wanted.  Low overhead using 20MB of ram.  Someday I will figure which extension and commands power down the display by comparision.  Rock on.
