I watched this video earlier today. I’m not sure how I feel about it. Some of the results sound like legitimate issues and some are kind of vague. Are the people having multi-monitor support issues using Gnome/KDE or are they setting up a niche tiling WM with a highly custom config?
It’s good that he has an audience where he can gather this kind of information but much of it isn’t very actionable. I don’t know how I as a developer or Linux user can help improve anything from this data.
I’d wager that good old fashioned bug reports to the specific software having the problem is a more useful tool.
