    First of all, this depends on the display type.

    Rule of thumb:

    Monitor --> 'Full' color range

    HDTV --> 'Limited' color range

    Now, the evil devil called nVidia makes changing this setting dead-easy via GUI.

    However, everyone else can enjoy some quality time with their PC to try to change this setting, especially so on Wayland:

    So, what are you waiting for?

    Go on, spent some well deserved time with your PC this holiday season.

    Cheers!

    Please read his statement agian.

    And the winner of the awkward, run-on sentence award goes to...

    Can you explain a bit more? at SDDM before I login, I switch between X11 and Wayland, I mostly use Wayland now after tons of bugs got fixed but dont see any issues hopping back and fourth.. Arch btw

    One of waylands most promised feture was - we are dropping all this Xorg legacy layer, so we will be more power efficient. An years, ans years - wayland was eating battery as t-rex, while Xorg with all that legacy was doing way better. Ok - finally in XXX years - in GNOME!!!! session ( I bet they nbever touched a single app requiring Xwayland to show this bullshit benchmark) - wayland has some advantage. COme on , guys - you promised efficiency by design and at the end it takes years of work and huge pack of investment RedHat put in this piece of garbage.

    My main feeling - it personal, so may be wrong - wayland by design is ugly piece of garbage. It is good for paranoid corporations for all this bullshit security. Its my desktop. I see it all - so I do not care if one of my apps will be able to capture screen of my other app. For personal linux this security is useless. Ok - lets see if the moner RH invested into wayland will finally make something better that my beloved stone-age Xorg, bu so far I do not trust this tests. By the way my Mate Xorg session use kind of 3-4 watts with firefox, thinderbird, messengers etc lounched if i do not have anything running. Up to 1.7 watts on minimum brightness on pure Mate (no browsers, vibers, telegrams) , 0.8-0.9 watts when screen off. So all those measurements looks like dirty wayand marketing.

    Then you know it works pretty much exactly the same as waypipe for Wayland over SSH. The main difference is that the former is built into OpenSSH, the latter not yet (probably just a matter of time though).
    Its interesting; I can't see the OpenBSD developers adding waypipe for something they don't use. Perhaps someone will add it to the openssh-portable release as a set of patch kits?

    But if it is anything like tunneling VNC, you don't particularly need it integrated with SSH. Mainly because the server is the server (Xvnc) rather than the client providing the server (Xorg).

Yes it also runs into the reverse where you have a Wayland settings from running Plasma and you attempt to run back on X11 and now X11 Plasma fails to start and is throwing you back to SDDM. Yes this is KDE Plasma known issue.

    Ideal world you would be able to switch between X11 and Wayland modes with the same user account but we are not there yet.

    Plasma 5 works here on Wayland, it feels snappier, but it still has bugs that overall render the X11 experience better, which is why I'm still on X11. This is mostly KDE's fault because Gnome on Wayland works far better (at least for me), but I hate Gnome, so...

    IIRC traditionally laptops have been more problematic on Linux than the PC.
