Questions tagged x
This tag can be used for questions regarding the X Window System. For X Version 11 you can use the tag x11.
I guess people know they are running X, but they are less confident about the exact version. I think this tag description is misleading: it will always be "X Version 11".[*]
Anything that asks about different versions of X11 is probably a history question about how x11 came to be. Or a question about some successor to X. These uses don't seem important enough, to justify preserving the x tag.
I asked about this on Chat. Jeff Schaller suggested a Meta question to gather consensus. Stephen Kitt noted that there is a site privilege that allows you to propose tag synonyms, but that this particular case is only allowed to be handled by a moderator. (The system detects x11 as a "version-specific synonym" of x).
Please up-vote, down-vote, comment or answer accordingly :-).
[*] See "Why do we never hear of X10 or X12?", answered by the very same Stephen Kitt on Retrocomputing StackExchange. (I was told my original explanation of why was misleading, due to omission of essential details).
As per the link, X11 has been used since 1987. And there will probably not be an X12. In the unlikely event that X12 does appear, I expect we can easily sort out any resulting problem when it happens.
