Suggested reasoning
The following are my own reasoning with least knowledge.
Question 1, 2 are relevant for users who are still trapped between upstart and systemd system management; systemd is becoming more common but remained controversial and unanswered.
Question 3, 4 are relevant for users who want to configure modifier keys on their keyboard; Sounds like common problem but unanswered.
Question 5 is relevant for users who are still struggling to use HiDPI display with certain desktop environment, in this case, kde; HiDPI users on Kubuntu might be able to answer this today.
Question 6 is relevant for users who prefer cross-desktop solution to install something, in this case, using xdg tool to install new icon; Despite cross-posted, it seems to be a straightforward question but remained unanswered.
Question 7 is relevant for users who own wacom drawing tablets and still stuggling to use in Ubuntu; While 'Wacom Intuos L' is being asked, there is no canonical answer that explains why pressure sensitivity for Wacom drawing tablets sometimes work and sometimes doesn't work. This article on Ubuntu Wiki has dated instructions that might need clarification.
How I select
At first, I use the following criteria in the search bar on Ask Ubuntu. The result was very low (4 results).
is:question views:250 answers:0 duplicate:no closed:no wiki:no score:10
So I lowered the criteria by reducing the question score filter from 10 to 5 and refine my search. Then, many questions flooded the page (133 results).
is:question views:250 answers:0 duplicate:no closed:no wiki:no score:5
From there, I browse the results briefly and proceeded to view random questions that may be relevant and somewhat familiar to many users.
Despite my suggested questions, none of those are applicable to myself. Should suggested questions above are all disqualified, then someone should refine the search and post another meta answer.
