This is a new install.

I downloaded the server image.

Hitting the alternate console I can see CMA errors being posted.

On the primary console I get a mouse pointer, but its just a black screen.

There seems to be GUI elements posted that I can't see as moving the mouse around changes the pointer from a arrow to a finger.

The bootup looks like it went fine.  Looks like it is at a post setup screen of some kind.

If there is specific info needed I can post that would help?

Is this an update, new install, what Desktop image are you using?

It should work with that.

Yes, you can edit the grub cmd line, it's also dependent on the
desktop. It could be things other than CMA though, but you'll need to
provide more detailed information.
