It is something I was about to ask long time ago - could anyone give me a tip on how to, conveniently (terminal command, for example) disable screen backlight all-together?

It would be very nice for using device outdoors, in direct sunlight - our trans-reflective screen does awesome job to light-up image just by the power of sun (when holding device in position that gives max sun reflective illumination - indicated by seeing everything very clearly, but in b&w/greyscale only, kinda like e-ink, increasing brightness to max only makes picture *less* visible), and backlight, even on min, not only waste power, but get in the way, too.

Ideally, it would be best to integrate 0-backlight into Simple Brightness Applet package - as an additional "check field", like "backlight always on" is already - but, for a starter, knowing a sole terminal command would do.

Thanks in advance,
/Estel

Setting brightness in settings to max or lowest first, and disabling power save feature, could perhaps stop it from changing brightness again when ambient light changes.

That'd be fantastic.

The natural question then is, is it possible to turn the backlight off and keep the lockscreen on to continuously display the clock, missed calls, messages, etc?

I got the opposite: I want to have my screen enabled but have a disabled TS, makes it all easier in my bike mount [no accidental clicks while navigating]

Cool...although, having tried it now, it seems that the disabling doesn't survive locking the screen.

Which is good, as you would need ssh to re-enable touch input, otherwise
