Hi guys
How do we load & tweak color profiles in Fedora
(without using external sensor-devices) ?
My Lenovo Thinkbook built-in screen has different (and
not adjustable in BIOS) color temperature what my
external DELL shows - they are quite different thus
annoying.
https://wiki.archlinux.org/title/ICC_profiles: Monitor
profiling without additional calibration hardware
It has been a few years since I used this. No idea if it
works under Wayland, so you might have to
chose Xorg at login. Once you have acceptable profiles
Wayland should use them.
It's been a while and I've changed my hardware setup - which
now makes it even more puzzling.
Now I have two "identical" Dell monitors - P2418D - and
colors are different, one has whites cooler whereas the
second's whites (thus other colors) are warmer.
I've been playing with 'colormgr' but am unable to make
screens to look the same.
I've also done simple "factory reset" within monitors.
Perhaps that "warmth" is something else and 'colormgr'
cannot fix it - would anybody know?
Or hardware calibration - event though it's the same monitor
- is the only "fix" here?
thanks, L.
