The Night Light filter, also known as Blue Light filter or Color Temperature filter

Hi,

I would like to use the

The Night Light filter, also known as Blue Light filter or Color 
Temperature filter,

Is there a package in Guix to support this?

I am using MATE Desktop and I couldn’t find anything.

I heard that Gnome supports that, also KDE but both I haven’t installed 
(yet).
I don’t know if Enlightenment Desktop has that option, but because of 
several problems I don’t use Enlightenment often.

My laptop Tuxedo (german company) supports that, but to enable it in 
Guix, I would have to write a programme to use the Tuxedo programme, 
which is impossible for me.

Kind regards

Gottfried

If you're looking for an external tool (not included in the desktop
environment), I'd suggest gammastep.  I'm not sure whether it works both
on X and Wayland, but I think it does!

I use redshift — does that do what you need?

Best wishes,

Hi,

thank you very much.

I installed redshift,
but where can I find it?

in the shell:

gfp@Tuxedo ~$ redshift
Trying location provider `geoclue2'...
Using provider `geoclue2'.
Using method `randr'.
Waiting for initial location to become available...
Unable to obtain GeoClue client path: Timeout was reached.
Unable to get location from provider.


what can I do?


Kind regards

Gottfried

For Germany I use this:

redshift -l 48:8 -t 6500:3500 &

Actually, there is a Redshift service for this functionality,
documented here:
https://guix.gnu.org/manual/en/html_node/Desktop-Home-Services.html

I am not familiar with Tuxedo software, so I hope this matches your
needs.

For some reason, my response was not posted by the list - I used a "respond to the list" option of Evolution.

Here it is again:
