I want the night light applet from GNOME shell 3.24
You can install redshift
from the following command:
sudo apt install redshift
You can just add redshift
to your startup if you are OK with redshift
pulling its own default settings. Or, you can configure it manually like I have laid out below.
You can get your Longitude & Latitude from https://www.latlong.net/
You can then create a config file that redshift
will use in your home folder at ~/.config/redshift.conf
. Add the following lines to it, and I added the lat
and lon
for Portland, OR. But you can add the ones for your location. Make sure to set location-provider=
to manual
then if you want to use the LAT and LONG. However, the application geoclue2
should be able to find your location. Change the temp-day
and temp-night
to your likings.
~/.config/redshift.conf
; Global settings
[redshift]
temp-day=6500K
temp-night=3500
transition=1
gamma=1.000:1.000:1.000
location-provider=geoclue2
adjustment-method=randr
; The location provider and adjustment method settings
; are in their own sections.
; These are the location for Portland, OR.
[manual]
lat=45.523062
lon=-122.676482
Then all you have to do is to add just the application of redshift -c ~/.config/redshift.conf
to your startup applications and it will use your config file at startup by default.
You can check your redshift
parameters by running redshift -pv
or redshift -p
:
terrance@terrance-ubuntu:~$ redshift -pv
Location: 45.55 N, 122.68 W
Temperatures: 6500K at day, 3500K at night
Solar elevations: day above 3.0, night below -6.0
Brightness: 1.00:1.00
Gamma (Daytime): 1.000, 1.000, 1.000
Gamma (Night): 1.000, 1.000, 1.000
Solar elevation: -22.482371
Period: Night
Color temperature: 3500K
Brightness: 1.00
terrance@terrance-ubuntu:~$ redshift -p

Hope this helps!
