Post subject:  Power on off monitor from keyboard/remote R6

I have a cheap remote that actually sends keystroke commands so no lirc is involved, very responsive. I wanted to use the power button to turn the monitor off and on. After searching I found several scripts none that worked for me.
Problem one
dpms force off blanked the monitor but did not turn off the backlight

Problem 2
no version of script seemed to toggle on although any button would unblank the screen

solution

xmodmap to map keys (plenty of info on setting this up)

vbetool dpms off turned the monitor off sadly turning it on required a ctrl-alt-bksp

Then reading about fluxbok keys I found the simple answer

Open /home/mythtv/.fluxbox/keys

add the following line (assuming you have used xmodmap to map the power key to XF86PowerOff

XF86PowerOff :ToggleCmd {ExecCommand sudo vbetool dpms on} {ExecCommand sudo vbetool dpms off}

Restart X and test.

It has no logic it just toggles the commands but assuming after turning it on the next likely command it to turn it off it works great and is simple.

I would love it if that worked with my tv. Do you know of many displayes/monitors support that method of turning off/on.

Damn near any relatively new one.

There are some posts for the lirc method just substitute the vbetool command if the dpms force off does not turn off the back-light

obviously if you use a keyboard or a remote like mine that emulates one, my method would work great.

This is like the remote I got

I gave it a go, but my TV (samsung la46m81) kept the backlight on and displayed HDMI2: No Signal. I was hoping the TV would actually turn off.
