power off lcd display

[Kj4bnh]

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.

[Kj4bnh]

Rich, no joy, xset command not found.

Then you did not load Xlibs.

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

... but the 14 does not turn the back light off.

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

[Kj4bnh]

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.

[Kj4bnh]

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

[gerald_clark]

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.
