From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Looking for a simple, time-based night color control (self.linux)

I used to be on KDE. It had night color control integrated. Then I switched to XFCE, and it did not. So I installed Redshift.

Oops! Redshift requires location access so it can automatically set the color temperature based on the sun's position in the sky. Now it doesn't work when the network is deactivated. And on my system, I can't set it to redden/bluen based on the time only.

I go to AlternativeTo, to find an alternative. It looks like all of them do the same thing, or are discontinued.

Is that what everyone wants? Is that all that's out there? Just ""smart"" programs that access your location to automagically change the colors based on astronomical events?

Even on Windows you could set the night color control based on the time. Am I living in a backwards world where Linux uses the invasive complicated way and Windows uses the private simple way?

Is there a simple program out there that can set night color control with only the time, none of that other crap?

I don't have an alternative program to suggest, but there are some workarounds for using redshift.

First, in the config file, you can set the location provider to manual, then specify a lat/lon and it will use that location in its time calculations. I do this on my laptop, and it works well except for when I cross multiple timezones - things are obviously off a bit.

Second, with the caveat that I haven't tried this, it looks like you can also manually set dawn/dusk times in the config, which sounds like what you're after.

See man 1 redshift for more info.
