libvibrant Legacy

NOTE: This library is in the process of being replaced.

A simple library to adjust color saturation of X11 outputs.

vibrant, with it's library libvibrant and it's command-line tool vibrant-cli, allows you to adjust the color saturation on X11 outputs, as long as the CTM property is supported.

Usage

$ vibrant-cli OUTPUT [SATURATION]

Get or set saturation of output.

OUTPUT is the name of the X11 output. You can find this by running xrandr. SATURATION is a floating point value between (including) 0.0 and (including) 4.0.

• 0.0 or 0 means monochrome
• 1.0 or 1 is normal color saturation (100%)
• if empty the saturation will not be changed

Examples

150% on DisplayPort-0

$ vibrant-cli DisplayPort-0 1.5

Monochrome on DisplayPort-0

$ vibrant-cli DisplayPort-0 0

Reset DisplayPort-0

$ vibrant-cli DisplayPort-0 1

Only query current saturation on DisplayPort-0

$ vibrant-cli DisplayPort-0

Compatibility

vibrant supports most modern GPUs.

AMD GPUs

• Your card needs to be supported by the AMD Display Code kernel driver

NVIDIA GPUs

• Currently only the NVIDIA proprietary driver is supported
• Support is handled by libXNVCtrl, which should be bundled with most installations of the driver

Confirmed working

• NVIDIA GeForce GTX 660
• Radeon RX 5700 XT
• Radeon RX 5600 XT
• Radeon VII
• Radeon RX Vega 56
• Radeon RX 580
• Radeon RX 470
• Radeon R9 270

Building

This project uses CMake.

Dependencies

• libX11
• libXrandr (possibly bundled with libX11)
• libXNVCtrl (possibly bundled with nvidia-settings)

For Fedora

dnf install cmake make libX11 libX11-devel libXrandr libXrandr-devel libXNVCtrl libXNVCtrl-devel

Basic building

$ cd <project directory>
$ mkdir build
$ cd build
$ cmake ..
$ make install   ## Please note that if you get an error, you might have to run this particular command as root.

Additional steps if it won't build

If you get the error ./vibrantLinux: error while loading shared libraries: libvibrant.so.1: cannot open shared object file: No such file or directory, you need to run echo "/usr/local/lib64" | sudo tee /etc/ld.so.conf.d/local-x86_64.conf and then sudo ldconfig.

The binary will be called vibrant-cli and will be linked to libvibrant.so.0
