    While not talked about as much as raw performance and other factors, but in the recent testing of the Lenovo ThinkPad T14s Gen2 laptop with AMD Ryzen 7 PRO 5850U, it was observed that the GNOME Wayland session by default on Ubuntu 21.10 is delivering better battery life / lower power consumption than using the GNOME X.Org session.

      Please read his statement agian.

        Anyone can comment about X11 vs Wayland color reproduction? Intel (8 gen & 6 gen) / HDMI Port / Arch / Plasma X11 have better color reproduction vs Wayland.

          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!

            Sorry to say there are a set of different bugs like above. Where different setups you will go splat swaping backwards and forwards between plasma on X11 and plasma on Wayland.

              I did read his statement. He was not clear on if user had already gone into x11 version of KDE. The hard reality here there are bugs that if you have logged into KDE Plasma as X11 then you attempt to use Plamsa on particular hardware and software configurations you are doomed.

              Yes and if you are following the pattern over and over again of trying X11 KDE first then trying KDE wayland second on trouble hardware you will keep on getting the same failure result.

But now I'm on my new Ryzen 9 PC with built-in AMD GPU (APU?) and I still can't get it to work. On various distros, that is.

                Makes me wonder if the Wayland fanboys are secretly not on Wayland either, but love it so much that they trick people into thinking it works.

                  I dipped into Plasma Wayland briefly last week. Chromium still doesn't behave correctly. Loads of "papercuts" and when I tried benchmarking Horizon Zero Dawn I was getting 65fps rather than 85pfs on Plasma X11

                    This is a new PC, so yes, it's a clean account. I never restore any settings. On my laptop it was a relatively clean account as well.

                      Again, waypipe works fundamentally the same as X11 over SSH: There's a proxy display server on the SSH server side and a proxy display client on the SSH client side. (Yes, this means X11 over SSH doesn't really require X11's network transparency, which is just as well, since X servers haven't enabled network sockets for client connections by default for years)
