The Night Light filter, also known as Blue Light filter or Color Temperature filter, is a bit hard to find in Ubuntu 20.04. The Night Light tab is now in shown in the title bar, next to the Displays tab. These 2 tab labels look like they are just a title, but in fact they can be clicked on. (BTW it's Settings -> Devices -> Displays: Night Light in Ubuntu 18.04.)
I just switched to Ubuntu, and on Windows I was using f.lux. I was able to set the temperature to a certain time and leave it at that, it wouldn't change at all.
Now I installed Redshift and I can't do that anymore. Could some one help, please?
I would like to see everything on my computer screen in grayscale (like say the kindle screen). How do I do this?
What is the procedure to calibrate the monitor and what software to use?
Edit: I think what I mean is "colour profile" if that's what it is called. I happened to notice that the same photos look very differently indeed on my home laptop and on other computers…
How do I go about changing my laptop's display's color temperature? And I don't mean through something like the Red, Green, Blue sliders in the NVIDIA config menu. I'm talking about like adjusting in degrees, like editing a photo's white balance.
So now I've found Redshift and it's doing me pretty good. I thought it might be helpful if I out here the command I'm using.
redshift -t 5000:5000 -g .5
By adding this to my start up commands I should be good.
I'm still open to other suggestions, because I'd like something that actually edited my xorg.conf or something like that.
