Redshift is an application that filters blue light by changing the color temperature of your
monitor based on the time of day. This helps mitigate eye fatigue and even aids in
improving sleep patterns by not interfering with the daily rhythm. The application
communicates with the graphics driver, which enables it to modify the gamma ramp, the
device that controls how color is represented on the monitor.
This guide covers every possible installation method for Linux Mint 22. Each step is
explained in detail.
What is Redshift?
Redshift is an application that reduces blue light on the screen at night to reduce eye
strain. It makes the monitor appear less bluish in the evening and more bluish during the
day, and follows natural light rhythms projecting across the day, aiding the circadian
rhythm.
Redshift shifts the color temperature of your display automatically with time of day. During
the day, it uses standard colors (approx 6500K), and gradually shifts to warmer (3000K)
redder colors in the evening by curtailing blue light.
Prior to the installation of Redshift, ensure that your system is up to date and meets all
prerequisites. This is the complete guide for the installation of Redshift on Linux Mint 22,
step by step, so that it is simple to follow:
Checking System Compatibility
First, check if your system has the required graphics capabilities:
lspci | grep -i vga
Listed below are explanations for each part of the command line:
lspci:ThiswilldisplayallPCIdevicescurrentlyattachedtoyourPC.

3. 2/14
lspci: This will display all PCI devices currently attached to your PC.
grep -i vga: This will snipe lines with “vga” regardless of its case for the graphics
card.
You get something like “VGA compatible controller: VMware..” or “VGA compatible
controller: Intel Corporation…” This is useful in knowing what graphics drivers you have,
which will determine if Redshift will work with your system.
Method 1: Install Redshift Using CLI
This is the simplest and most reliable method for the users. The APT (Advanced Package
Tool) approach is recommended because it provides stable, tested packages that work
well with your system. It provides automatic dependency resolution and allows easy
upgrades using the system update routine.
Step 1: Update Your System
Package updates keep the security patches, bug fixes, and compatibility changes up to
date. It is important to check for conflicts when installing new software:
sudo apt update && sudo apt upgrade
Step 2: Install Redshift and Redshift-GTK
The redshift-gtk package is mainly used to freely control Redshift via a tray icon and
GUI, while redshift itself is the main utility:
sudo apt install redshift redshift-gtk

Here,
redshift: a command-line application that allows a user to control the color
temperature.
redshift-gtk: System tray integration, Toggles On/off, indicator, Menu for
configuration as key provided.
Step 3: Verification
Check if the installation is successful:
redshift -V
This command prints the version and build details.
Step 4: Launch Redshift
This will start Redshift in command-line mode (you won’t see a tray icon):
redshift

5. 4/14
Method 2: Install Redshift Using GUI
Using GUI (Software Manager) turns out to be the easiest way of installing Redshift and
also provides an easy way (but no terminal) to access Redshift GTK which has a tray
icon.
Step 1: Open Software Manager
Click on Menu, on the bottom left side of the screen. Look for Software Manager, click
on it (the icon is a bag with the Mint logo):
Step 2: Search for Redshift
Software Manager is opened, go to the search bar, look for redshift, you can type
redshift and press Enter:

6. 5/14
Step 3: Select Redshift from the Results
Redshift or Redshift GUI will be listed. Click on the specific package to view its contents:
Step 4: Click the Install Button
Most users will prefer Redshift-gtk more because of how user-friendly and convenient it
is. Click the Install button:

7. 6/14
On the Redshift package page, click the Install button:

8. 7/14
You’ll be asked to enter your password (your user account password):
This installs the package using your administrator privileges. The Software Manager will
download and install Redshift. Once done, the Install button will change to Remove,
indicating successful installation.

9. 8/14
Step 6: Launching Redshift
Go to your menu for the Redshift section, where the application should appear, and click
it:
How to Configure Redshift on Linux Mint 22?
You can fine-tune Redshift’s performance by making a config file, even though it operates
effortlessly. It also has an interface with the system package manager. This is useful for
maintaining regular updates via system updates.
Commands for additional checks:
which redshift # Shows installation path
dpkg -l | grep redshift # Shows installed package details
Verify the version you have post-installation:

10. 9/14
apt policy redshift
This tells you the repository that provided the version you have installed, as well as other
available versions.
Understanding Redshift Configuration
Familiarizing yourself with configuration enables you to customize Redshift using terminal
commands/ arguments, but the config file method is much more suited for permanent
changes.
Creating the Configuration Directory and File
mkdir -p ~/.config
nano ~/.config/redshift.conf
Comprehensive configuration file:
[redshift]
#Global settings section
temp-day=6500
temp-night=3000
fade=1
gamma=0.8
location-provider=manual
adjustment-method=randr
[manual]

11. 10/14
#Manual location settings
lat=40.7
lon=-74.0
Detailed configuration parameter explanations:
[redshift] section – Global Settings:
temp-day=6500:
Color temperature during daytime hours in Kelvin
6500K is neutral white, similar to daylight
Higher values (7000K+) are cooler/bluer
Lower values (5000K-) are warmer/yellower
temp-night=3000:
Color temperature during nighttime hours in Kelvin
3000K provides significant blue light reduction
2700K-2500K for a very warm, candlelight-like appearance
4000K+ for a minimal but noticeable reduction
fade=1:
Enables a smooth transition between day and night temperatures
1 = enabled, 0 = disabled
When enabled, changes occur gradually over time

12. 11/14
When disabled, changes are instant at sunrise/sunset
gamma=0.8:
The gamma correction value affects the overall brightness curve
Values less than 1.0 make images appear brighter
Values greater than 1.0 make images appear darker
0.8 provides a slight brightness increase for easier viewing
location-provider=manual:
Specifies how Redshift determines your geographical location
Options: manual, geoclue2
The manual requires you to specify coordinates
geoclue2 uses system location services
adjustment-method=randr:
Specifies how Redshift communicates with your graphics system
Options: randr, vidmode, drm
randr: Modern X11 method (recommended)
vidmode: Older X11 method (compatibility)
drm: Direct driver communication (newest systems)
[manual] section – Location Settings:
lat=40.7:
Your latitude in decimal degrees
North is positive, South is negative
Example: New York City ≈ 40.7°N
Used to calculate sunrise/sunset times
lon=-74.0:
Your longitude in decimal degrees
East is positive, West is negative
Example: New York City ≈ 74.0°W (hence -74.0)
Used to calculate local solar time
Redshift is now installed and running. Your screen will adapt to day and night
automatically with the changes.
How to Uninstall Redshift on Linux Mint 22?
Uninstalling Redshift on Linux Mint 22 renders the tool for adjusting screen colors
useless, thereby regaining system resources. This is helpful if the user no longer requires
it or prefers another method.

13. 12/14
Method 1: Uninstall Redshift Using CLI
In case you have installed the GUI version (redshift-gtk). First, we need to uninstall the
entire package:
sudo apt remove redshift-gtk
Second, if you only installed the command-line version:
sudo apt remove redshift
Remove Leftover Config Files
To remove personal configuration files as well, running the following command is
suggested:

14. 13/14
sudo apt purge redshift redshift-gtk
Removing purge will erase the program and the system-wide config files as well.
Delete User Config Files
If you wish to erase the config that Redshift holds, located at the user directory, you can
run the command:
rm -r ~/.config/redshift.conf
Otherwise, if you used a folder, run this command:
rm -r ~/.config/redshift
Method 2: Uninstall Redshift Using the GUI
You can also uninstall it through the GUI. Go to Software Manager -> top right search
bar -> type redshift. Look for the two options, which are ‘Redshift’ or ‘Redshift GTK’.
Redshift is the command-line version. Redshift GTK (or redshift-gtk) has the tray icon and
GUI.
In the Redshift package, you will see a Remove button if it is installed. Click Remove:

15. 14/14
You can then confirm that Software Manager will uninstall the package, and the Remove
button will switch to Install, confirming Redshift has been uninstalled.
Conclusion
As for installing Redshift on Linux Mint 22, start by accessing the Software Manager
from the application menu, and then search for Redshift. You can either install Redshift
for the command line or Redshift GTK, which has a system tray icon. After selecting a
package, click install, and input your user password when prompted to authorize the
installation. Post installation, launching Redshift from the application menu allows it to set
the screen color temperature based on the time of day automatically.
