In response to Wayland Breaks Your Bad Software
I say that the technical merits are irrelevant because I don’t believe that they’re a major factor any more in most people moving or not moving to Wayland.
With only a slight amount of generalization, none of these people will be moved by Wayland’s technical merits. The energetic people who could be persuaded by technical merits to go through switching desktop environments or in some cases replacing hardware (or accepting limited features) have mostly moved to Wayland already. The people who remain on X are there either because they don’t want to rebuild their desktop environment, they don’t want to do without features and performance they currently have, or their Linux distribution doesn’t think their desktop should switch to Wayland yet.
I have a laptop with hybrid Intel+NVIDIA graphics, and I can say that offloading games and such to the dGPU while letting the iGPU handle everything else works with zero issues for me on Wayland.
On desktops where the NVIDIA GPU handles everything I don’t have that much experience on Wayland although when I did try it earlier this year it was surprisingly good, but with occasional dumb bugs like Plasma panels freezing or XWayland apps breaking in funny ways. Although honestly just a few years back running Plasma X11 on NVIDIA wasn’t much better than Wayland now.
