redshift, f-lux: Adaptive screen color temperature

I think this should be interesting to investigate:

https://launchpad.net/redshift

http://stereopsis.com/flux/linux.html

Especially if you are using your devices under low-light conditions.

Re: f-lux: Adapive screen color temperature

Since we have an ambient light sensor, maybe it could be used rather than lat/long lookups. Disabling the N900's auto brightness adjustment does not disable the ALS, so it could be used instead of brightness adjustments.

Re: f-lux: Adapive screen color temperature

redshift would be better to look at. Not only is it actually open source (unlike f.lux), it also has two methods to change the "temperature" rather than just one

That is true, the source for xflux is not released. I've posted this one as an idea for maemo based light adjuster.

You meant: https://launchpad.net/redshift

Re: redshift, f-lux: Adapive screen color temperature

I've tried the redshift this evening. In the evening I usually make all rooms darker.

It really feels better, turning of backlight makes it obvious.

Re: redshift, f-lux: Adaptive screen color temperature

This seems very interesting. Are there any screenshots/images we can all see?

There is a ppa for redshift at launchpad. The thing reduces amount of blue, the display becomes redish. It is easier to read in the dark.

Re: redshift, f-lux: Adaptive screen color temperature

Have you tried it on device? It does seem interesting (doubt screenshots will help, as it is about current display settings in current ambient light)

Any thoughts?

I've tried on diablo (all packages present) and failed to configure

I think the configure script might be broken.

BTW: after several days of using redshift on my laptop, I think it really works better than dimming of the screen. If combined with dimming it works great for my eyes.
