I've installed the fluxgui package from Killian Valkhof's PPA (https://launchpad.net/~kilian/+archive/f.lux) and started the applet by pressing alt+f2 and typing in fluxgui.

The inidcator icon shows up and I've entered my latitude/longitude, but my screen colors aren't changing. The applet fails to open its preferences dialogue as well.

What gives? Any solutions?

    so is there anyone who have done it? –  Mar 22 '13 at 21:33
  • f.lux is now available for Ubuntu through Launchpad PPA. You can install this using Terminal. Execute the following commands one-by-one to install f.lux on Ubuntu. sudo add-apt-repository ppa:kilian/f.lux sudo apt-get update sudo apt-get install fluxgui After installation it'll appear in Ubuntu indicator. Click the f.lux icon from the app indicator menu and click on Preferences. Now give your latitude and longitude. If you don't know yours, that's okay. You'll find an option beneath to find your latitude and longitude. It'll direct to a web address. Name your area in the search bar. Select t – ZachM1 Jan 23 '13 at 06:36

    This actually installs and launches fine, but it does not change temperature at all on Ubuntu 12.10. – Yuan Mar 30 '13 at 10:25

    I got f.lux running but the preference panel won't open. So not sure if it's actually doing something. – Voles Oct 22 '13 at 14:51
  • @Voles, I think you're having the same problem as the rest of us. The good news is that F.lux just pushed an update (the first in a number of years), so these issues may soon get fixed... maybe. – Louis Thibault Oct 23 '13 at 10:47
  • I've got f.lux working on OSX, exited about the update! However I'd like to use it on Ubuntu as well. Thanks for you reply! – Voles Oct 23 '13 at 11:56

Having the same problems with f.lux and there doesn't seem to be any fix for this right now.

But Redshift seems to work fine on Ubuntu 12.04.

I got f.lux working by downloading the xflux daemon available from http://justgetflux.com/linux.html. I cannot get the GUI panel to open but can configure xflux via the command line and the f.lux icon says it is active.
