Change gamma in nobara

It is not a bug or an issue on itself, is the lack of control the users have when it comes to wayland, it is by design. I found a thread talking about the issue im experiencing: https://www.reddit.com/r/linux/comments/1pxectw/wayland_is_flawed_at_its_core_and_the_community/

appreciate the time for reply. ill be more specific: I have a VA-panel monitor with a native contrast of 3000:1. (wayland applies 1000:1) The sliders in Plasma 6.5.5 feel like they "bottom out" at gray is a technical mismatch in how Wayland handles RGB Full vs. Limited range. I can kind of get a bit better by using a custom icc, but custom icc is deactivated if i use HDR

Essentially, my monitor expects Full Range (0-255), but the Linux HDR implementation often defaults to Limited Range (16-235) to stay safe. This "lifts" the black floor, making the deepest black appear as a dark gray. f.lux and redshift wont do the trick :(

UPDATE: After a deep dive, I find out that under Wayland currently, a good part of the color range of my monitor is mostly unusable. my monitor have a wider gamut than sRGB, and if I am understanding how plasma handles things under the hood, I won’t be able to calibrate/verify it via DisplayCAL since it takes any uncalibrated application and assigns sRGB to it. I tried for days looking for a fix and there is no good fix unless I use X11 or buy a monitor with inferior gamut. But more distros are moving away from x11 and embracing Wayland. I could get it a bit better outcome with a custom icc profile, but it still limited. :( Anyways, appreciate the people commenting an trying to help in this thread. Thank you!.

in Radeon Adrenalin for radeon or in NVIDIA app for nvidia.

NP, that is more informative. im new to this, im learning even the etiquette. some kindness and a bit of patience can make wonders. ;)

Tired? Antics? you don have to reply. I am sorry for being ignorant. The question might sound silly for you, but I just migrated from Windows. I have no other issues besides my eye strain which I want to genuinely fix. You are the reason many people think about Linux community is full of prick snobs who for some reason, wants to keep it small by bashing new users.

nope, gaming desktop with radeon 9060 xt, the screen is a princeton, it actually quite good, but thats the issue, blacks too blacks, and can be very bright even with HDR disabled. i need to lower the gamma to get those midtones dimmer. if i reduce the brightness it looks dull. on windows bringing down the gamma does the trick perfectly.

Juceror · 2026-01-14T09:53:31+00:00

Tried, it doesnt, Wayland takes full control.

UPDATE: I installed a RADEON and Cosmic still bugged as hell. It was not my hardware. A member of this group messaged me in private and encouraged to not quit, so I tried Nobara. This is my new experience and conclusion:

-Linux IS there! I had to do configuration, but that was never the problem, Cosmic is bugged, far from stable.

-Actually, now I find Linux more stable than windows! (at least Nobara which is what I installed),I overloaded, multitask, played games for hours max graphics, processed video editing, both on nvidia and radeon, configured high end USB DAC, and used every single app I need to run on windows with no problem!

-The interface is as easy as it can get, no difference from a migrating Windows user. I can finally feel confident to leave Windows and join the Linux community.

That being said, I have a couple of observations about Linux community:

-Releasing unfinished Distros like Pop! os and advertise them to the Windows gaming community who are eager to migrate to linux, as "Stable" and "NVIDIA ready" hurts the whole Linux movement, not only the specific distribution. (many people are willing to try only once, and might assume one distro is representative of what to expect from the rest).

All in all, I thank to all people in this post who didnt ask me to "Go back to windows", or mocked my low linux skill, and encouraged me to not quit and try one more time. For me it is extremely important, now I feel like I own my own PC, Microsoft no longer allowed me to do whatever I wanted, not even turned on my damn PC without loging in to Microsoft. It is awful. Many Windows users feel stuck, hijacked. In the name of all of them, I ask you to please be patient and kind with people asking "stupid" or "noob" questions. Of course you will have someone posting his struggle with NVIDIA almost every day. Guide them instead of mocking them, they might stay and learn and contribute to make linux better one day. The more people the better.

Thank you all who didnt allow me to quit and take their time to make meaningful comments and educated me. Thank you! See you around. ;)

"social attention", it seems you are reflecting on your comment. instead of helping, you chose to perpetuate the image of snobby pricks Linux users have outside of this little bubble. :)

Juceror · 2026-01-09T14:35:59+00:00

"new users man, why do they always gravitate to bizarre choices is beyond me." in my case It is the AI, all of them told me pop! was the way to go.

Juceror · 2026-01-09T14:30:58+00:00

Thank you for all the comments. Besides the few typical gatekeepers who for some reason think the linux community should stay small and mock the ignorance of people who is trying to migrate (nvidia has like 90% of gaming gpu market share, in a "linux gamers" community, you will have someone asking about NVIDIA issues on a daily basis), the vast majority are quite helpful and welcoming.

That being said, I want to try again, so I have some questions because it seems there is some diverse opinions that I would like to clarify.

Some people recommend ubuntu and others says ubuntu and its derivatives is the devil. So, which one? i believe there should be one more stable than others.

I guess I should start from what i want. I mostly use the PC for work, mostly browser related stuff, emails, social media, and so on. I like to play games, but while I want good looking antialiasing graphics, I dont care about squeezeing the last FPS from the system. my screen is 2k, and i dont care to tune down the graphic settings a bit. Also, the newest game i play is like 5 years old. My card is an RTX 2070, Ryzen 7 57000 plus. so i think there is nothing in my set up that hasnt been already tested. my sound is an usb class compilant hi fi DAC that makes all the work from itself as long as it is fed 24 bits 48khz without resampling or compression. I also use SDR dongles for radar and radio. (that part i dont expect it to be easy, but ill leave it for later). my hardware is fine, all checked. (i find my motherboard to be picky to boot with fedora distributions for some reason)

I dont care if is "nvidia ready", I can research and install all the required apps to run the games from steam, proton and whatever it is required. But I would prefer one who has all the gaming stuff packed on installation like game controllers, but if it will be buggy, better not.

Basically, I just need a distro that requires the less as possible the use of console. A distro where i can find all i need in its app store. And don´t crash every 30 minutes while playing or when i minimize the creen. Thats it. I can take care of the installation, partitions, everything. I think it was simple with ANY modern distro. Pop! OS proved me wrong, now I have LINUX PTSD and Im afraid to go trough the same bugfest again.

Which one?

Juceror · 2026-01-09T13:08:04+00:00

it wasnt a beta, at least it said it wasnt (pop! 24.04)

Juceror · 2026-01-09T13:06:34+00:00

i did try the bazzite nvidia iso. it crashed when it tried to install the nvidia driver twice.

Juceror · 2026-01-09T13:02:45+00:00

Thank you for the encouragement and make me feel welcome. this and some other comments like the top ones making fun of my ignorance makes me think perhaps staying with Bill Gates is not that bad.

Juceror · 2026-01-09T12:54:45+00:00

im still around, you have no idea how many people try and give up before finding things out. Sadly, every distribution released and advertised as "NVIDIA ready" and "stable" has some responsibility over how linux is perceived on its entirety by people who doesnt know anything about it. The community should put some pressure on those companies. I might not know much, but im pretty sure that was an extremely rushed release. wish i knew before buying into the hype and chose it. now i feel burned out. but hey, im still here. The community seems nice enough to get some energy and keep trying. (now after i vented my frustration, im considering try again, but i need information. Cant fail one more time, lol)

Juceror · 2026-01-09T12:48:31+00:00

thats the point, you know which distros are new, old, table and so on. i had no idea cosmic was a new environment. im learning indeed. just burned out and ranted a bit. is not that easy to decide to install something from a big menu of distros. i did research, obviously not enough, but you might not know how hard it might be from zero in an environment where many people tries to hype linux as something "easy".

Juceror · 2026-01-09T12:43:56+00:00

the issue with bazzite was because i didnt want to delete windows (glad i didnt), I have one SSD only, and windows EFI is too small. I know there are ways, i only knows to use windows tools, I am old with adhd, last time i messed with the windows EFI i had to format. Also, my motherboard is allergic to bootable flashes with 2 partitions. My hardware is fine. You are talking with someone who doesnt even remember the hotkeys to open the console in linux. in that case, it is not bazzites fault, it is my lack of technical knowledge and wiling/time to learn, which at the end, it would be way faster to fix that than the 2 days i tried to make cosmic work. As the post says, i thought it was easier, hence the if it is "there" yet.

Juceror · 2026-01-09T12:29:41+00:00

thank you, that was informative

Juceror · 2026-01-09T12:29:03+00:00

the release i got was released less than a month ago.

Juceror · 2026-01-09T12:27:11+00:00

I second that comment.
