F.lux simply doesn't work...
I love f.lux, I use it every time in my Windows partition. Nevertheless, on Linux, more precisely on Ubuntu, that doesn't work.
I've installed the package through the PPA repository, like it is mentioned on this github page, I lauch f.lux. Then I enter my location and... that is where I'm stuck. I'd like to mention I have already tried to change the color temperatur but after that, it's still don't work...
If someone could help me I would be grateful :)
Diclamer : I'm French so I have erase the ZIP code location, and I'm not an English people so it is possible that there are mistakes in my text. If so, forgive me!
Same thing here: because I'm french, I have entered the lat/long information of my place.
With or without f.lux: no difference, even at 8 PM.
In the console, some errors are displayed:
(fluxgui:13053): dbind-WARNING **: 09:03:56.541: Couldn't register with accessibility bus: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.
As root, no error but f.lux doesn't do anything else displaying an applet.

Welcome to xflux (f.lux for X) This will only work if you're running X on console. Found 1 screen. Sorry, we only support 8 and 10-bit displays right now.
Same exact issue here, but I am in the US.
I've installed the PPA via the install instructions from the github page. I can open the f.lux indicator applet and enter my lat/long. But I never see the lighting change on my monitor. Even when setting to a lat/long that I can confirm is at night.
After some digging, seems f.lux may just be broken. I followed the steps from this ticket and confirmed I'm having that issue:
I went and installed redshift, and that works for me.
