turn off display backlight on ubuntu server

[shinew]

Hello, I have a dell xps laptop running Ubuntu Server 8.10. I can't figure out how to turn the display's backlight off. Can anyone help?

thank you very much!

I was looking to turn off the LCD backlight on a Dell Inspiron 2650 running Ubuntu Server 8.04.2. I found: http://www.installationexperiences.com/2009/01/turn-off-lcd-display-backlight-with.html
I tested by connecting to the laptop via SSH and doing
1. sudo apt-get install vbetool
2. sudo vbetool dpms off
3. sudo vbetool dpms on
4. sudo vbetool dpms off
I'm pretty new to Linux, so I don't know what the side effect to this are, but I'm happy so far, and hope this helps.

Hi 2buntu, although I've noticed that it actually turns itself off after a while, thanks for the reply and vbetool works great! good to know.

xset dpms force off

that does not work. Unlike vbetool, xset is a "X" level utility. vbetool is already in all my systems by default(Intrepid, 8.10 desktop & server, Mint Felicia 64-bit), so I didn't have to install anything.

The added benefit of using xset is you don't have to use sudo to get the access to shut down the monitor.
