Jokes on me. The new driver fails at the most basic of levels. turns out, the display device no longer exists in any internal directory the external devices can find. I can't even project my screen. Rolled back the update, F.lux works fine, will continue to use and support, best wishes~ Silverfish Disaster

@herf Is there something new? I really miss this feature too.

Do you have an antivirus running that might have f.lux as a false positive? And can you find an update to your display drivers?
