Difference to Redshift
Closed this issue · 4 comments
I'm wondering what bluegon can do better/different from Redshift? Maybe you should also add that to the README.md.
I myself am not too familiar with redshift and also f.lux which seem to be the most popular competitors to blugon. One major reasoned I created blugon for, was the ability to control the gamma values on particular daytimes instead of the way redshift does it which is only night and day.
Blugon is also a lot simpler and you can even say less sophisticated.
I like the idea of a comparison table for the readme, but would like to hear from other people what their reason for using blugon was!
I would really like someone to look at #8. I am not sure with all the comparisons! Are there other categories that are missing?
From my limited interaction with Redshift (thank you for suggesting it btw), all I know is that it can apply color temperature relative to the current color temperature, such as:
redshift -O 3000 (for 3000K)
as opposed to absolute: redshift -P -O 3000 which would act like blugon -r -o -b scg if /home/user/.config/blugon/current contains the value 3000.0.
-O TEMP One shot manual mode (set color temperature)
-P Reset existing gamma ramps before applying new color effect
for tty/drm you'd have to append -m drm or else -m randr is assumed! (edit: and it won't fallback to drm if randr fails, although it says that it's trying next method but no more methods to try)
-m METHOD Method to use to set color temperature
(Type `list' to see available methods)
$ redshift -m list
Available adjustment methods:
drm
randr
vidmode
dummy
Specify colon-separated options with `-m METHOD:OPTIONS'.
Try `-m METHOD:help' for help.
I initially thought it was a bug, but I can see its usefulness as a feature now.
My only usage of blugon thus far was to set color temperature in Kelvin (once! and leave it like that, regardless of time of day), for both tty/drm and for X. So I made this blugon-inspired toy(to do just that) before I knew of Redshift.
