Got two machines running with Fedora 26. Both have been almost flawless. Really solid.
What qualifies as "almost flawless" ?
One of the two machines, the HP Envy, has a weird graphical artefact that happens through a combination of the lock screen and automatic screen rotation when being picked up causing the screen to get weird and show part of hte desktop. Everything still works, the lock screen just doesn't get 100% coverage. Probably Cinnamon only issue.
I know with Fedora Gnome, we can switch between Wayland and Xorg. Cinnamon still uses Xorg but it could be happening because Fedora doesn't include any proprietary drivers too.
Actually, I got it working with bumblebee-project installed. It did not work in Korora 25, but seems to be working in 26.
I prefixed the wow-64.exe with optirun and it just worked. Great framerate too. I just need to work out the mouse capture part yet. But that's not a big deal since I don't play that game much anyways. It was just easy to test with because it's on an external drive. Hopefully it's not like that in NMS.
My cpu fan is still running full speed from the glxgear test, even though it's way cooled down by now. A reboot may fix that, though.
I hope Fedora 26 stays just as it is. "Works" great so far. More so than 25.
