Doesn’t seem to be an option in the MATE settings panel for loading a colour profile… Perhaps I need to install some extra MATE desktop environment addons for this?
So I’m not entirely sure the display profile has been installed, I certainly don’t notice any difference in the display…
Perhaps more research is needed! Or perhaps something like the Cinnamon desktop may be more suitable considering it already has colour management installed?
Until a few days ago, I had Linux Mint 19 Cinnamon on one of the SSDs, but since then I switched to Manjaro (got a slight touch of DIstro fever, you know). Give me a few moments to see if I can dream up a swift experiment to show what will/does not happen.
On the Desktop you have your monitor profile, entitled myProfile.icc
Open a colourful image somewhere on the monitor, to make it easier to spot any changes. Start a terminal.
Type dispwin -c <Enter>
then dispwin -I myProfile.icc <Enter>
a) Did you spot any difference when executing the first -c?
b) Did you spot any difference when executing the first -I?
I recommend that you use a distribution and desktop envireonment, that does proper color managment such as Mint Cinnamon. I have had the same problems as you with other distros. Actually as far as I know the only DEs that can deal properly with color managment are Mint Cinnamon and Gnome. I you use dispwin to set the profile, the system eventually forgets to load it. Also, darktable has a nice command line tool which can check whether your color managment works properly, the command is in the darktable manual, don’t know it by heart.
@betazoid Thanks for the reply, betazoid The reason I opted for Mate / XFCE in my various distro hopping hops was I baulked at Cinnamon using 1.2Gb after logging onto the Mint Desktop! Mate & XFce idle at 400-550mb. Although I do have 16gb ram on my system, so perhaps not really an issue…
Here is the output of the darktable-cmstest:

darktable itself was built with colord support enabled
primary CRTC is at CRTC 0

Your system seems to be correctly configured
But yes, perhaps a distro & desktop environment which has color management from the outset may be a good idea, particularly since I’m using my system for photo editing. Hmmm.
@Claes, I can’t say I’ve noticed any difference between loading a linear profile with dispwin -C, and loading my calibrated profile using dispwin -I myprofile.icc . I used a profiling image (PDITarget.jpg off the internet), displayed in Xviewer. So either my monitor is pretty close to calibrated from the outset (It’s a Benq PD2700Q Designer Monitor which is supposed to be pretty well calibrated by the manufacturer), or my spyder2express isn’t actually doing anything calibration wise.
Not true, KDE also has color management. In fact, KDE’s system settings also includes a calibration feature that will use a colorimeter to calibrate your monitors, without you needing to use DisplayCal
However, I still use DisplayCal as it provides a vastly superior set of features. This particular KDE settings feature is new though, so it makes sense for it to be somewhat barebones.
OK, then: who has a really lousy monitor profile to send to Brian,
like one with switched channels or whatever, just to make it easy to
see whether profile on/off works? @Elle ?
