I need help for calibration color display in linux mint

[obsidian crane]

I moved windows 10 to linux mint, when i was using windows 10 it has accurate colors, but agter changing to linux mint the color of the display became very dull, if anyone knows how to fix this please let me know

[kind dust]

The only thing I can think of is brightness controls but I'm not sure that is even what you're talking about

[obsidian crane]

no its not about brightness bro its about gamma

[obsidian crane]

its so frustrating i love mint, in windows it has accurate color idk why in mint showing dull color

[red blaze]

https://cinnamon-spices.linuxmint.com/applets/view/286

[obsidian crane]

i tried this bro, but still the color its not accurate, red colour looks soooooooooooo dull

[red blaze]

well I don't know much about colour profiles, my guess is you'd have to download one from your monitor's manufacturer, then set it up in Mint under the appropriate settings thing for that

[obsidian crane]

okay how to do that

[red blaze]

also make sure ur not in software-rendering mode.

check in terminal with inxi -Gxx to be sure the GPU is in use and has driver functional

[obsidian crane]

okay i will let u know idk much about this,

[red blaze]

second line shows driver. looks good.

[obsidian crane]

u mean the device-1?

[red blaze]

yep

[obsidian crane]

okay so what should i do now

[red blaze]

Monitor-1 shows your monitor's model.. u can also confirm on its backplate

[obsidian crane]

backplate?

[red blaze]

oh it's the built-in screen?

[obsidian crane]

yea

am using it on laptop bro

[red blaze]

does it look too washed out/bright?

[obsidian crane]

yea bro its looks awful washed out and also bright, when i was using windows 10 it has accurate clr this is happening in linux mint only bro...

[red blaze]

give me me a couple minutte

[obsidian crane]

i find linux more smooth than windows i dont wanna go back to windows cuz of this problem :((

[obsidian crane]

sure bro tnx for helping me

[obsidian crane]

See this guy also experiencing same as me lol

[red blaze]

open a text editor now please

[obsidian crane]

yep done

[red blaze]

copy all of that into a new file

all you have to do is put the latitude and longitude of your general area

then save the file as redshift.conf

[obsidian crane]

i copied it and pasted it

[red blaze]

and put that file directly in /home/$user/.config

google ur city, on google maps

and click it.

then in the address bar, you will see latitude number,longitude number

or just google the coordinates, and put for lat n long in the file

[obsidian crane]

okay first i have to paste that file in the place u mentioned right, so next i have to check the longitude number?

[red blaze]

make sure u pasted every line in the file I sent. exactly as it is shown

[red blaze]

yes your city x,y coordinates

[obsidian crane]

yep

[red blaze]

just for sunrise/sunset reason

[obsidian crane]

wait lemme paste that conf file first

[red blaze]

this explains how it works

[obsidian crane]

oh lol i have to do it first

[red blaze]

the top red title is where it must live. no red writing is to exist in the file

[obsidian crane]

yep so all i have to do is to copy the longitude right

[red blaze]

latitude

[obsidian crane]

yea both

[red blaze]

both, and no spaces after the equal sign

[red blaze]

turn off and disable this applet 100%

once that file is saved with all the correct information in it, and put in the folder I told you, then type 'redshift' in the start menu, and press enter

[obsidian crane]

i have to delete that?

[red blaze]

you can just disable it from Manage Applets

do not run redshift til u do

[obsidian crane]

i cant see disable option

[red blaze]

manage applets, and uncheck it

or delete it, i dont care

[obsidian crane]

yep done

[red blaze]

the settings I put here for gamma increase the red slightly, lower the green substantially, and keep blue at a decent value of 0.8

but you can adjust them later if you don't like. you just have to fully shut down redshift from the tray , before changing the conf file,.. then save the changes in the conf file, and restart redshift again from start menu

[obsidian crane]

8.9744603,77.2360807,15z

which one is lat and long

[red blaze]

if you want the night colour temperature same as day value, then just make day value=night value

8.9 is latitude. are you in an arctic region?

siberia, finland?

5 decimal places is enough for both

[obsidian crane]

nah bro i am from tamil nadu india

[red blaze]

oh right it's 8.9 degrees north of equator

[obsidian crane]

8.9744603 = lat
77.2360807 = long

[red blaze]

yep

[obsidian crane]

right

[red blaze]

even 4 decimal places enough

[obsidian crane]

wait i have to download redshift?

[obsidian crane]

yep

[red blaze]

it should be included

if it's not, then i guess do it

[obsidian crane]

i dont see redshift app in start menu

[red blaze]

get redshift-gtk package

DISABLE NIGHTLIGHT in Mint 22

[red blaze]

dont use together or crash

[obsidian crane]

middle ones right

[red blaze]

yeah, it should pull in redshift base

[obsidian crane]

i wont use night light probably haha

[red blaze]

did u put file in ur home .config folder?

redshift.conf exact spelling

[obsidian crane]

/home/$user/.config
to this directory right

[red blaze]

yes. ur own user account name ofc.

ctrl-H for hidden files

[obsidian crane]

done

[red blaze]

ok. start up redshift then. u should see the effect visually right away

[obsidian crane]

why?

[red blaze]

show the text of the file.. open it , take a screenshot

[red blaze]

error on my part, 2nd line

press enter after [redshift]

and delete any space before the word temp..

you may also want to put day colur temp to 6200 maybe now since it's probably day for you

[obsidian crane]

like this

[red blaze]

delete teh space i said

[obsidian crane]

uhh does it matter because all i want my colors to look accurate... and also should i have to change often when at night?

[red blaze]

also, another error on 7

line 7

[red blaze]

u can set it once to another colour temperature at night n leave it for ever

line 7 error

no space after location-

[obsidian crane]

that's all?

[red blaze]

error on line 6

[obsidian crane]

space?

[red blaze]

no spaces between any numbers

[obsidian crane]

how about now

[red blaze]

stretch the window wide and show ss

line 9 must be one line

stretch window wide to be sure

[obsidian crane]

its working onw

[red blaze]

put temp day 6200

[obsidian crane]

it looks purple

[red blaze]

ok nevermind.. so shut down redshift

from the tray, right click and quit

[obsidian crane]

yep i did

[red blaze]

put red value to 0.8 in file

the gamma order of numbers is red green blue r:g:b

[obsidian crane]

yep done

[red blaze]

then save and relaunch

[obsidian crane]

its blinking wtf

my screen

[red blaze]

log out and back in

[obsidian crane]

yep

in windows its so easy to calibrate,🥱

hey i think its software issue in some softwares its showing slightly accurate colors

[red blaze]

anyway, now that you logged back in, relaunch redshift. how is it?

[red blaze]

KDE Plasma desktop environment is also very easy to do it.

[obsidian crane]

See in inkscape the red is think

In 1 notification should be think clr as well but it looks dull and also in browsers

[red blaze]

idk put the red gamma lower than .8 then. maybe .7

[obsidian crane]

Which linux uses kde?

[red blaze]

Tuxedo OS, Kubuntu, Feren OS, Spiral or Sparky KDE, Fedora KDE

[obsidian crane]

fedora? bt it has less customization right

[red blaze]

not really.

[obsidian crane]

i downloaded fedora and installed linux mint lol

[red blaze]

all KDE environments are highly customizable.. only thing is Fedora uses rpm packages, not deb

so it's different family, slightly different terminal commands. though u can use KDE Discover (the graphical software center)

the other ones I mentioned, especially the first three, are all ubuntu-based, like Mint. The two S ones are Debian based

[obsidian crane]

so its very easy to calibrate display in fedora?

[red blaze]

did u try this?

[obsidian crane]

its looks so blue bro

[red blaze]

any kde distro

[obsidian crane]

okay wait a minute i have fedora file i will text u after booting it

[red blaze]

typically, the Applet i had u turn off or remove would allow u to adjust R,G,B easily and perfectly

[obsidian crane]

i already deleted that bro

[red blaze]

but u must turn off redshift 100% (logout and back in and make sure the icon is not in tray) to run that gamma applet

[red blaze]

are you going to do a test drive of it from USB?

[obsidian crane]

yea lets see if its easy calibrate

[red blaze]

alright

[obsidian crane]

i will text u in a min bro

btw bro am i interupting u😅

[red blaze]

nah

[red blaze]

are you sure you got the fedora kde ISO last time, or the gnome one?

[obsidian crane]

I already have the fedora 41 workstation iso file bro

Gnome is linux mint right

[red blaze]

NO

Fedora is GNOME. unless u specifically got the KDE ISO

[obsidian crane]

So there is 2 version of it?

[red blaze]

yep

[obsidian crane]

U said fedora is kde lol

[red blaze]

what's the iso filename exactly

[obsidian crane]

Wait I'll show u

Here

[red blaze]

hard to tell from that

check fedora website

[obsidian crane]

Can I show u the site that I downloaded

I downloaded the for Intel and amd x86_64

Lol there is separate site

[red blaze]

https://fedoraproject.org/spins

[obsidian crane]

Should I download this one

[red blaze]

i think Fedora will be using KDE as its official desktop this year. For now, the workstation version is Gnome.

get that one in ur last pic

[obsidian crane]

Gnome???

Sry I don't get it 😅

[red blaze]

just get that one in last pic. delete old file

[obsidian crane]

Yep

I'm downloading the kde plasma now

[red blaze]

do u have ventoy usb?

or UUI usb, also good

[obsidian crane]

In Linux mint it has usb writer for bootable

Usb image writer

[red blaze]

it may work

[obsidian crane]

Yea I used fedora writer for Linux mint

[red blaze]

if not get ventoy flasher from ventoy.net

[obsidian crane]

Yep

Btw what's the difference between gnome and kde

[red blaze]

see youtube. huge difference

[obsidian crane]

Yep I find some softwares like inkscape is works smoother without lag in Linux rather than windows

I mostly do game dev on godot and Capcut for edit that's all...

[red blaze]

kde desktop is more traditional desktop layout like windows 95-windows 7 /cinnamon

gnome is more keyboard based and operates and looks very different

[obsidian crane]

I see

Btw where you from tho

[red blaze]

plasma 'classic' application menu

Reactionary theme used.

Just right-click menu button and choose 'Alternatives' to pick it.

[obsidian crane]

U r saying I should use this theme?

I am on fedora kde plasma rn

[red blaze]

u dont have to, just saying there's efficient menu options

[obsidian crane]

Yep I love old looks lol

[red blaze]

and if u want settings to look more familiar, set it to ICON mode, instead of text list modee

[obsidian crane]

What's that

[red blaze]

when u hover on any setting icon, it shows sub-categories it contains

[obsidian crane]

Bro it looks neat bro ngl

[red blaze]

open settings. it's in menu as a favourite (probably an icon of switches box)

from there u can find Display and mess around

[obsidian crane]

For display calibration?

[red blaze]

and resolution, screen scaling, everything

[obsidian crane]

Lemme check

I think it's working

Right screenshot is crct accurate clr

I used icc profile

[red blaze]

i cant tell from shots

[obsidian crane]

I took it from my phone camera

[red blaze]

there's also RGB gamma in advanced i think, or scroll down

i mean if it looks good to u, great.

[obsidian crane]

Yea it looks yoor like my windows

😁

[red blaze]

cool

check if Discover works

and internet, video playback, mic and sound output

[obsidian crane]

Yep bro

[red blaze]

see what version plasma . just search 'info center' in menu

or do inxi -SGxx in terminal

anyways, im out. goodbye

[obsidian crane]

Yep see u later thanks for help bro
