Hi

I have installed turnkey LAMB server to my old dell laptop. That LAMB is based on Ubuntu 10.04

It works well, but I can't turn that LCD off.

Laptops LCD is on even when its closed, so its eating a lof of energy.

I have searched a lod, and xset doesnt find my screen.

I can use "fn"keys to dimm screen, but not to switch it off.

So How could I switch of that lcd?

Does it have a screen saver function? If so, tell it to use blank screen. Most OSs have a screen saver function, unless its a headless server with no gui, even then, they usually have a timer that turns the screen off after a certain amount of time under power settings. Im not sure where you would go to configure this for linux.

Does this laptop have an external display port? Maybe use the fn + # key to toggle to the second monitor, blanking the LCD, and see how the battery life is after that.

Something interesting, might have to install this or may be installed already - https://bbs.archlinux.org/viewtopic.php?pid=506200#p506200

It has no gui, only webmin. AFAIK it has no screensaver, atleast it wount start automatically.

Its turnkeylinux LAMB server, Installer disk was <200MB so there is not much other than whats necessary.

Xset might work, but it doesnt detect display. Even if I add to /etc/environment "DISPLAY=:0.0" it doesnt detect display.

[code root@lamp ~# xset dpms force off

xset: unable to open display ""

[/code]

FN +key to use external motitor doesnt work eighter.

EDIT: Thanks, vbetool works well.
