Re: Amber screen?

f.lux appears to be abandonware; redshift totally did the job. 

I am so one of the cool kids now. (Get it? Get it?) 

Thanks for indulging me...

Redshift is probably the thing to use with X11.

The docs on that say that "color temperature is changed by
setting appropriate gamma ramps", but it looks like it's actually using XCB
to scale *all of the points* on brightness-curves rather than just
adjusting the exponent used in normal gamma correction. I guess that
makes sense: you can't change your whitepoint by messing with the "xgamma"
command, because changing the gamma value just changes the exponentiation
of the values *between* a given blackpoint and whitepoint.

You could presumably also do this by defining a custom color-profile
using Argyll or something, but I have no idea how to do that.
It looks like Gnome Color Manager will let you tune your whitepoint
*after you calibrate*, but you need to hook up and ColorHug or other
calibration hardware first and actually get through the calibration step.

If anyone knows (or finds out) how to actually generate a custom color-profile
without doing calibration per se, I'd love to hear about it.

I'm a fan of f.lux and redshift (the linux equiv).

Was he running vintage terminal emulator Cathode?
http://www.secretgeometry.com/apps/cathode/

Looks like the glass screen of a  VT420 (in my experience) and friends.
