I've replaced my screen with "special" screen (Pixel Qi) that when the backlight is off, basically doubles as e-paper so it is visible in sunlight. The Fn+F6 shortcut works great to turn the backlight off while keeping the LCD active (which is exactly what I need).
The problem is that the moment i move the trackpad or use the keyboard, it "wakes" and turns the backlight back on.
The obvious easy solve would be being able to turn the brightness all the way down, but the lowest setting is still SOME backlight, and i need it off.
So the goal is either:
1) use terminal to turn backlight off while keeping LCD/computer on and usable
2) find out how to turn backlight all the way down using "slider" or terminal input ("echo" a setting)
3) keep whatever Fn+F6 does from caring that the keyboard/trackpad is being used and not turning backlight back on
I working with an Acer Aspire One running Mint xfce (would this be unique to that distro? I'm open to switching distro's if there another where this wouldn't be an issue)
A few things I've tried that DIDN'T work...
- Using xrandr to turn the display off didn't work, as it appears to control the entire screen, not just the backlight.
- xbacklight. The lowest setting is not off and so had the same effect as turning the screen all the way down with the slider.
- echo'ing the backlight setting files themselves, of which there are two: intel_backlight and acpi_video0. Even at 0 for either/both, this didn't get the backlight off. (Btw, is the fact that there are two different controllers messing me up?)
I did run a check to see if Xorg recognizes the Fn+F6 keystroke and it does NOT, so I'm wondering where/how that change is being effected in the first place and how to override the waking from that "lever".
I'm fairly new to Linux and command line, so descriptiveness and small words are appreciated!
Thanks for any all help!
