Dual screen support

[babolivier]

Hi,
I've seen that I'm not the first one asking this question, but I didn't find an answer to it, so here I am: I'm using a dual screen configuration with my laptop's screen and an external one. Once I've set up f.lux on this laptop (Ubuntu 14.04 LTS), I clearly see changes on my laptop's screen, but not on my external one (even if the first one isn't the primary display). Is there a way to have f.lux effective on both screens (as it is on my Windows session)?
Thanks.

I think there are two ways:

1. Install A 64-bit version with multiple monitor support - https://justgetflux.com/linux.html (link on the bottom of the page)
   OR
2. Follow the guidelines from this gist - https://gist.github.com/robertboloc/9feaa9150926efa4175a

[I've tried the first one with Ubuntu 14.04 and the second one with Ubuntu 15.04]

I have a setup with two AMD Radeon HD6450, Debian, Xfce and four monitors.

With Xinerama xflux starts, but doesn't change the color temperature.

Today I disabled Xinerama and switched from the propritary to the radeon oss driver and configured my multimonitor setup with Xrandr by hand.

Now xflux changes the color temperatures, but only on one graphics card/two monitors. The other card/monitors just stay like they are. :/
