Re: not excited about the 'wayland' thing
Ive been using Linux on my workstation and my laptop for 5 years or so now. X11 is *fine*, but PulseAudio is a complete mess. Where X11 falls down is handling multiple GPUs properly and HiDPI support, which I do admit is down to the desktop environment/display manager I am using. Oh and not to mention the whole weird configuration of it all.
I'm currently on 20.04 with Budgie on top of GDM and whilst I can technically use Wayland, it doesn't work quite right outside of Gnome. But with 7 virtual desktops and it all setup right once you go past a certain number of windows the whole thing crawls to a juddering mess on a dual E5-2660 v3 20 Core setup.
Running Gnome with Wayland is super smooth, things seem snappier despite the fact it is the more heavyweight DE. Real world numbers I can't provide but I think given the kind of stack I would be measuring the only metric can be snappiness/responsiveness; super subjective I know. I find X11 just seems to lag or judder at times, no matter what DE/Display Manager you are using. I didnt *feel* this with Wayland until the system was entering swap and was under extremely heavy load, but the juddering wasn't as jarring.
I'm going to try a test move to Fedora 34 using KDE on top of ZFS. PulseAudio on 20.04 is broken and I think Wayland needs the support of people using it for it to get to where it needs to be. As for X11 forwarding, VS Code over SSH is far superior IMHO and NoMachine is superb as well. I imagine Wayland will screw me on NoMachine Virtual Sessions though. Oh and everything over WireGuard keeps it uber secure. Haven't needed X11 forwarding for some time now.
