I run a dual boot of Ubuntu and Windows.
Windows running f.lux has a noticeable effect.
I have redshift and flux installed on Ubuntu but neither has an visible effect.
I'm looking for help in debugging this or any alternative software to make the light less harsh on the eyes.
Installation of flux from ppa see here: f.lux setup.py on xubuntu 16.04 results in error
While I believe I installed redshift from the software installer app.
redshift into terminal results in this.
Trying location provider `geoclue'... Started Geoclue provider `Geoclue Master'. Using provider `geoclue'. According to the geoclue provider we're at: 43.64, -79.39 Gamma ramp size too small: 0 Failed to start adjustment method randr. Trying next method... Using method `vidmode'.
And it just seems to stall from there.
The details of package for
redshift installed from the Ubuntu Software Centre says this package provides gtk+ integration.
xrandr: Failed to get size of gamma for output default Screen 0: minimum 1920 x 1080, current 1920 x 1080, maximum 1920 x 1080 default connected 1920x1080+0+0 0mm x 0mm 1920x1080 77.0*
redshift -v results in the same thing as redshift but followed by
Status: Enabled Period: Night Color temperature: 6500K Brightness: 1.00 Period: Night Color temperature: 6471K Brightness: 1.00
Then the same combo of 3 statements, with color temperature decreasing until it reaches 3700k, and it just repeats the fact it's at 3700k
Period: Night Color temperature: 3700K Brightness: 1.00
No redshifting visible effect as far as I can tell, still.
