Does anyone else here use f.lux on Linux? I installed the Ubuntu version but not only does the "pause/unpause" option sometimes do nothing at all but other times it simply forgets to change the colors.
I have it working reliably here (64-bit Ubuntu 12.04), though it is noticeably lacking a lot of the configuration options available in the Windows/OS X versions.
Tried it 2 or so years ago, had same issues mentioned by others, discovered redshift, been working perfectly since. Maybe flux is good now too, don't know.
