qtcurve-gtk3

end users might want to run Gtk applications (e.g. Firefox).

major pain points. For instance, until a few years ago, getting uniform looks between GTK, KDE and Qt applications was largely a solved problem, thanks to e.g. projects like QtCurve (there were several other solutions, QtCurve was just the one I liked most). Good luck with that today (see e.g. https://github.com/QtCurve/qtcurve-gtk3) Basically, except for Bluetooth and proprietary graphics driver, there's nothing that "almost works" today which didn't "almost work" ten years ago, either, except it probably got rewritten at least once. > Also what is IVI? this: https://www.ni.com/ivi/what.htm ? Nope, it's short for In-Vehicle Infotainment systems. It's one of the very lucrative markets for Linux solutions, because the competing solutions are either tied to a specific big player's interest (Android) or super expensive (QNX). Video entertainment in general (IVI, smart TVs etc.) is the main force that drives graphics and UI-related development in Linux. It's not a bad thing (quite the opposite, I certainly don't miss using VESA drivers...). But it does mean that, for the people doing work on major components of the graphics infrastructure, desktops aren't a priority. It needs real community effort in order to be turned into a viable desktop option, and that's pretty hard considering the rate at which developers are being driven away.
