Calibrating HDR possible?

Hi,

Ive got a great HDR monitor and i've been using it for gaming. Its an awesome miniled (Q27G3XMN).

Colour's looks very different to windows though. Im on KDE bazzite atm and I feel like there's a greenish tinge. Its very obvious when going from SDR (which is calibrated from windows) to HDR.

I havent been able to go deeper and improve/change it.

\- Can i calibrate colours? Or is there a way to override?
\- Is there an app to do it?

Thanks.

What specifically sets your preferred distro apart from the others, FOR YOU?

I recently bought a new laptop and while I wait for it to be delivered I've been reading a bit about the various linux distros and their advantages / disadvantages. Now, I've used Debian (and a bit of Ubuntu) as my main OS on various laptops and desktops for about a decade now, but I think I want to branch out and try something new. I'm particularly interested in trying one of the rolling release distros like Arch or OpenSuse tumbleweed, mostly just because I've never given them a fair shot. That being said, it's difficult to find good comparisons online that aren't just repeating the same high-level talking points like "Kali is for security while Debian is for sys-admins".

What I really want to know is, what are some of the key features unique to your distro of choice that really sets it apart from the rest in interesting ways? I'm looking for neat things you can do with your package manager, useful software packages, or interesting design choices that affect the way YOU, specifically, interact with your OS; not things like desktop environments that aren't inherently tied to the distro.

Also I'd love to hear about the interesting ways you interact with your OS, what you use it for, and any sort of unique customizations that are possible because of your choice of distro.

Thanks y'all!

I want to get into utilizing optical storage mediums (blurays) for media preservation and long-term/archival storage but I need some insight!

My interest in bluray and optical storage mediums in general have grown exponentially for the last few days and I want to get myself an external bluray reader/writer for my Linux PC (Im on Fedora 42 KDE) and some blurays for long-term storage and media preservation. I however have never used bluray before or used optical discs in any advanced technical sense. I know how to create partitions and filesystem's for hard drives but no idea how optical drives work exactly.

I also wonder how blueray utilization (burning, playback, storage etc) is done today as finding clear up-to-date info about it seems to be a little fuzzy. What is the go-to software? What filesystem's are being used for storage on blurays that are available on Linux? Is there any general knowledge that I should know? And are there any newer optical storage mediums on the horizon that might extent from bluray?

I'm up for questions if you want further information!

KDE Haruna video player is surprisingly good after years with smplayer

I've been using smplayer for the last 10 years, it was an ok replacement for PotPlayer when I switched away from Windows, over time I got used to its quirks and it did most of what I wanted, but unfortunately it has a tendency to break with updates.

Rotating videos worked on and off. And for the last few years it just became unresponsive for the first 5 seconds after loading a video. After last smplayer or mpv update broke the aspect ratio of rotated videos, I started looking for alternatives.

VLC doesn't have all the features. QMPlay2 is closer but isn't as customizable and wasn't stable for me.

And then I stumbled on Haruna and it's just... perfect.

Performance is much better than smplayer, no issues with rotating video and aspect ratio according to metadata. It took me 10 minutes to rebind all the keyboard shortcuts to the same ones smplayer uses via a familiar UI. And it has all the features I want, autoloading files from a directory into a playlist, single instance, adjusting speed via keyboard, screenshots, zoom, per-frame navigation, subnoscripts support... The only thing missing so far is an OSD with video technical details (resolution, code, bit-rate).

I never heard Haruna mentioned before, and it's surprisingly powerful. Kudos to George Florea Banus and other contributors.

IF you dualboot with Windows, how often and why do you boot into Windows?

I keep Windows 11 installed for those (more and more rare) times that I just can't figure out how to do or run something in Linux. Typically it's just my GPU glitching out in Linux that forces me to consider booting into Windows. What I mean is, when I'm experiencing crashes in Blender, sometimes I boot into Windows, load the same file up, and I don't get the same annoying crash in Blender, for whatever reason.

Other than that, I haven't used Windows for anything in the past year, even for gaming, or video conferencing for work. And every stinking time I need to get into Windows, there are forced updates waiting to be installed.

I'm getting to the point where I think I'm ready to completely nuke my Windows install and go 100% with Linux. Fedora 42 is completely stable, no glitching, all my hardware works, all default drivers, nothing broken. (Well, except my 8-year-old Microsoft Modern Keyboard with Fingerprint ID which doesn't have a BT pairing button. For that one edge case I have to copy the bt keys from windows registry and import them in Linux to get it working. But I am annoyed about it enough that I'll probably just go get a different wireless keyboard.)

Anyone else in a similar situation? Any similar/different experiences?

Capture scrolling screenshot in Linux?

Hello. I'm using KDE on Fedora and CachyOS. I want to capture a scrolliing screenshot, i.e a screenshot of an entire long webpage as one image in any of the tools in Linux. Is this possible?

I already tried Spectacle, a default screenshot tool and it did not work. Any ideas on how to capture such long screenshots of web pages is much appreciated.
