Auto adjusts screen gamma based on notebook battery life for Linux systems.
GammaDaemon should work with any Linux laptop.
Run either of the following:
bash
cargo install gamma_daemon
bash
cargo install --path ./
If you do the above method, it has to be in the root folder.
First, run
bash
cargo build --release
Then copy the binary to where you want to put it; For example, in /usr/bin/:
bash
$ cp target/release/gamma_daemon /usr/bin/
To run GammaDaemon without running as root, create a udev rule that will allow users in a certain group to read and write
to /sys/class/backlight/(backlight)/brightness. For example, udev rules for users in the video group listed in the documentation for bulbb:
bash
ACTION=="add", SUBSYSTEM=="backlight", RUN+="/bin/chgrp video /sys/class/backlight/%k/brightness"
ACTION=="add", SUBSYSTEM=="backlight", RUN+="/bin/chmod g+w /sys/class/backlight/%k/brightness"
For more information, see the bulbb documentation.
GammaDaemon is configured in a .toml file. You can specify where to find the config file in a command argument: ```bash
gamma_daemon /home/
```
If no config path is provided, GammaDaemon will look in $USER/.config/GammaDaemon/conf.toml for gamma configurations. If GammaDaemon cannot find this file, it will use a default configuration.
Here is an example config:
toml
full = 240
low = 100
low_perc = 25 # out of 100
charging = 255
discharging = 134
unknown = 255
ac_in = 255
