I wonder how representative that is of actual software used. I would imagine hardware probes are run from installers and live systems quite frequently. I would certainly not expect several percentage points of "neither" in practical settings.
Yeah, but when was the last time you decided to upload hardware device data for a root server to some hardware survey? That is something almost exclusively done by the kind of people who want to show off their system in some way.
Especially on servers I make sure to attend in the software packages survey.
Just so that the holy-gods and kings of maintainers are aware of me, the peasant running old packages.
I would guess not very representative at all. I don't believe wayland usage is higher, like at all. Maybe in a limited setting like NEW installs of the most popular distros, just because they default to it. But the existing install base? No way.
This is a graph of recent reports (one year time frame). The total reports from all time are over 70% X11.
But since the statistics are based on one time uploads, there's no way to know how many of those systems are still in use, or still run X11.
