    But why does it end up washing out colors unless I amplify them in kwin? Is just the brightness absolute in nits, but not the color?

    The desktop runs in SDR and the color space differs between SDR and HDR, meaning you will end up with washed out colors when you display SDR on HDR as is.

    When you increase the slider in KDE, you change the tone mapping but no tone mapping is perfect so you might want to leave it at the default 0% and use the HDR mode only for HDR content. In KDE for example, colors are blown out when you put the color intensity to 100%.

    Why does my screen block the brightness control in HDR mode but not contrast? And why does the contrast increase the brightness of highlights, instead of just split midtones towards brighter and darker shades?

    In SDR, your display is not sent an absolute value. Meaning you can pick what 100% is, which is your usual brightness slider.

    In HDR, your display is sent absolute values. If the content you’re displaying requests a pixel with 1000 nits your display should display exactly 1000 nits if it can.

    Not sure about the contrast slider, I never really use it.

    Why is truehdr400 supposed to be better in dark rooms than peak1000 mode?

    Because 1000 nits is absurdly bright, almost painful to watch in the dark. I still usually use the 1000 mode and turn on a light in the room to compensate.

    Why is my average emission capped at 270nits, that seems ridiculously low even for normal SDR screens as comparison.

    Display technology limitations. OLED screens can only display the full brightness over a certain area (e.g. 10% for 400 nits and 1% for 1000 nits) before having to dim the screen. That makes the HDR mode mostly unuseable for desktop usage since your screen will dim/brighten when moving large white or black areas around the screen.

    OLED screens simply can’t deliver the brightness of other display technologies but their benefits easily make it worth it.


  • Yeah, I’m also on my third controller RMA. First the stick on the left controller started drifting, then the right controller’s plastic started peeling off and finally the right controller stopped working altogether.

    At least they did the third RMA for free way out of warranty.

    Had to buy a new headset cable on my own though when the display started flickering after 2 years. They also sent me a new plastic clip for the cable on the back when the old one broke and a new left speaker when it started crackling instead of requiring me to send in the full headset so that’s pretty cool.







  • It caters to a middle ground that barely exists, meaning it doesn’t have enough options for a power user and too many for a newcomer.

    For example, a newcomer doesn’t know what a root account is and doesn’t have to care, yet they have to choose if they want to enable or disable the account. They can also remove their administrator privileges without knowing what it means for them. I get asked what a root account is every time somebody around me tries to install Fedora.

    I recommend spinning up a Ubuntu 24.04 VM and taking a look at their installer.

    They have a clear structure on how to install Ubuntu step by step while Fedora presents you everything at once. They properly hide the advanced stuff and only show it when asked for it. They have clear toggles for third party software right at the installer and explain what they do. Fedora doesn’t even give you the option to install H264 codecs or Nvidia drivers.

    It also looks a lot cleaner and doesn’t overload people with too much info on a single screen. And yet it can still do stuff like automated installing and has active directory integration out of the box, where the Fedora installer miserably fails for a “Workstation” distro.

    The Fedora installer works, but it doesn’t do much more than that and the others do it better in many areas.


  • Long-time Fedora user here. I do not think Fedora is noob friendly at all.

    • Their installer is awful
    • Their spins are really well hidden for people who don’t know they exist
    • The Nvidia drivers can’t be installed via the GUI
    • There’s no “third party drivers” tool at all
    • The regular Flathub repo is not the default and their own repo is absolutely useless
    • AMD/Intel GPUs lack hardware acceleration for H264 and H265 out of the box, adding them requires the console
    • Their packages are consistently named differently than their Ubuntu/Debian counterpart

    I really like Fedora for their newish packages without breaking constantly. I still would not recommend it for beginners.



  • Yes, but it is the cause for having issues jumping between networks and never having proper IPv6 support.

    What issues are you having? I have no issues with switching between networks and using IPv6 on Fedora KDE.

    The only thing I ever noticed was that its stubborn with releasing its DHCP IP addresses and there is no refresh button in KDE. Disabling and enabling again usually solves that, although not sure if that is on NetworkManager or dhclient.

    Everything is “out of scope” with GNOME these days it seems.

    It is, that’s why it is not a suitable DE for people that need more than the basics. I wish they were better with adding advanced features but they are not and probably never will be.

    KDE might not be as pretty and flashy but it is pretty extensive when it comes to settings and fast with implementing new features.
