I am using Ubuntu 22.04 LTS on an HP Laptop. In Settings, there is a section for Colors under which my Laptop Screen is Not calibrated and when I try to Calibrate it, the button is greyed out, as shown in the picture.
A bit of searching shows that you need something else to actually know what the color profile is, and Add that profile.
However, I clearly remember checking out the Settings when I first installed the OS, and at that time, I remember clearly that the Laptop Screen had a profile. And that was after I changed the theme and Night Light, so it's not those things that are affecting it.In addition, I have the Bootable USB with Ubuntu 22.04 LTS, and when I did 'Try Ubuntu,' sure enough, the Laptop Screen was already calibrated with the profile being Default - HP Laptop 15g-br0xx.But even there, the View Details button was greyed out, and there isn't such a profile as that in the list on my installed OS.
My question is: is there a command to know exactly what color profile is the so called 'Default'? And is there a way to kind of auto detect that on my installed OS? I can, of course, reinstall, but if there's a way to do this without reinstalling, I'd prefer that.
