search command to turn off screen Solved

Question

Hello everyone!

It's all in the title: no, I am not a lazy person who is too lazy to press the screen power button...

I have a laptop and I am looking for the command that allows me to put the screen to sleep (to turn it off)

It must exist because we can set the screen to turn off in power management.

Thank you for your help!

Configuration: Debian Sid / kernel: 2.6.32-5-amd64 / KDE 4.4.3 / iceweasel 3.6.3

GOT IT !!!

found the solution: just type
xset dpms force off

and there you go, the screen turns off but ONLY the screen (the rest continues to function).
to wake it up, just move the mouse (or press a key...)

Good evening...

Often, you need to hold Fn+F4 or Fn+F5.. the function key is marked by a black screen with a star and an arrow pointing to a white screen... not always!
Best regards,
See you later

Hi!

Thank you for your response. Unfortunately, I don't have that option... I only have a button to put the computer to sleep (Fn+F1) but it doesn't work (not even under Windows, actually, you need to install the Dell-made program for it to work). But I don't want to put my PC to sleep, just turn off the screen...

After doing some further research, I found this: https://www.commentcamarche.net/faq/10146-mise-en-veille-activation-d-un-ecran
but it's not very nice...

I'm just looking for a command that turns off the screen and that can be turned back on by a simple mouse movement for example (exactly what the power management does when it turns off my screen after X minutes, but I want to be able to do it manually).

I understand what you want to do... but I don't have a Dell laptop!
It's strange that such a command doesn't exist... have you tried all the "function" keys?
Or Fn + arrow keys...?
On Acer laptops, for example, (Fn + arrow keys) is used for sound and brightness... you never know?
Otherwise, you can set the shutdown for a short time; if you're using it, it will stay on, otherwise it will turn off by itself after 2 or 3 minutes... removing the screensaver makes it manageable...
Good luck with your search...
Best regards,

Hello,  You need to use DPMS (Display Power Management Signaling): See: https://www.commentcamarche.net/faq/10146-mise-en-veille-activation-d-un-ecran  Best regards, Mr.

I can dim the brightness, but not all the way to off :D

@ swed: thanks, that's the link I posted just above... it seems quite complicated for not much, but well, if that's all that's left, I'll dig into that...

thank you for your help!

And in the ergonomics options, there's nothing for that? @+ -- "Who wants to climb a mountain starts from the bottom! " Signed: "Gillette" a.k.a. "nobody"! ;) (°!°)

To keep it "simple", just go to Control Panel => Hardware and Sound => Power Options => Change plan settings => and where you see "turn off the screen", you choose how long you want.

For me, this works and I have a DELL.
