If so, what is preventing you from switching to > the port? I'm running -CURRENT on all my systems. I have a "3rd Gen" HD Graphics 4000 that I'm running drm-next on but I'm about to revert to drm2 because of instabilities. Xorg spontaneously crashes, and doesn't on drm2. I also have a Haswell system running drm2 which I have not tried drm-next because SWMBO is particularly intolerant of stuff not working. I also ran drm-next successfully on a Sunrise Point-LP system with "Intel UHD Graphics 620" because drm2 didn't support the graphics chip before switching to linux to get the trackpad and sound working. I guess the situation is that your mileage may vary depending on your system. I'm OK with installing drm2 from ports, but at this point I'm not really OK with loosing drm2 at this stage because of the instability in drm-next on my one system. Ian --help
