F.lux for Linux

We're happy to announce a proper Linux f.lux GUI, along with a ton of bugfixes to the command-line app.

PPA install instructions are on the github page.

Here's how it looks!

xflux daemon (command line, but for X-Windows)

September 2013

A 64-bit version with multiple monitor support is available here: xflux64.tgz

A 32-bit build with support for multiple monitors is available here: xflux-pre.tgz

Sometime back in 2009

The 32-bit command-line version is available here: xflux.tgz.


The indicator project (GUI) was begun by Kilian Valkhof (creator of trimage) in 2010. A group of volunteer maintainers are fixing bugs currently.

f.lux maintains the command-line daemon.
