content: I installed 18.3 last week after a linux-haitus of a year or so. No drivers for my Vega64 and no way to make it work. Dicked around for hours testing the latest and recent kernels, latest mesa and dependencies, etc. Nada, neither open source or proprietary would work. Couldn't really verify if anyone else had got it working again on 18.3 either... So I deleted it and installed Fedora 28 Workstation. Full GPU acceleration OOTB with open source drivers, along with everything else. Probably won't go back to mint tbh. Not really sold on Gnome 3 though - might see what XFCE looks like these days - haven't used it in about 15 years!
