I don't even know how many different distros I've installed, tested, and used as a VM within Parallels Fusion on MacOS. A bunch. Never before have I had any graphics issues. The window manager appears to be crashing just about as soon as it launches. Any thoughts? I've heard some glowing reviews of KDE Neon and I really want to test it out.

Here's the link to a video of what happens. https://vimeo.com/258632560

I've been tried different things, no luck so far. Anyone got ideas?

I have the EXACT same issue. What I've had to do is type startx at the command prompt. That allows me to get to the desktop to install it.
