I installed f.lux via apt-get and replaced xflux in /usr/bin with the daemon for X-window (32-bit build with support for multiple monitors). I launched it, set my location and chose my favourite colour temperature (4200 K) and clicked Preview.
So far everything was fine, both my laptop and external monitor began to turn 'warm'. But after a second it lost efficiency and came back to '6500 K'. How to fix this problem?
