I wish Ubuntu (or other distributions) would give out numbers how many people install the proprietary drivers. So many Linux guys seem to dismiss games and 3D (which is certainly also used for VR, architecture, 3D modeling, simulations - and not just for games), so I'm somewhat curious how much it matters on the Linux desktop. At least personally I know more people using proprietary drivers on Linux than not using them, but I guess that's to be expected for a 3D developer ;-)

For me the thought of losing nvidia driver support on Ubuntu is rather scary given the current state of all other 3D drivers (and certainly other Distro's might follow with Wayland). I hope the status of other drivers improves a lot before that switch or 3D on Linux will be set back a lot.
