Comment 60 for bug 938751

same happened to me. I've never got to experience Linux in my whole life.
my post is here if anyone interested- https://askubuntu.com/a/1301856/1162787
I install Linux/Ubuntu, looked at the colour, not satisfied, think I can accept and use, after a few days- I move to Windows again. Totally unacceptable colour of display. I just wanted a peaceful OS, not garbage like Windows but Samsung gave Proprietary motherboard software for display colours on laptop pcs. The only way is Intel HD Graphics Control Panel, I found after I change display colour profiles from "Samsung Settings" software, the HD Graphics Control Panel- Display values got changed. Thats good news, I can use those values and change in Linux. But the problem is I can't choose contrast, saturation in xrandr! I can't choose the exact value of "Brightness : -11(minus)", in linux xrandr (0.99? 0.991?) neither can increase contrast in xcalib. What can I do? I got no option.
Summery: Some motherboard software changes HD Graphics Control Panel Display values, you can exactly use that info. But you can't convert them nor use them correctly in linux. there is no way!
So low priority. Not a single software made to fix this. Nobody cares? Just buy a colourimeter hardware? If UI, Display experience is worse, no one comes to Linux just to have Privacy stuff.
