As Patrick pointed out, this is clearly not an NVidia device.  You can
find out which driver is actually handling it, by running "lspci -v".
There will be a line with "Kernel driver in use:".

"lspci -v" gives me the following output:

This output is under Wayland. I have previously installed the nvidia
proprietary driver from Negativo17 via dkms, and from what I can see
from the Xorg log, Xorg is loading that driver and the corresponding glx module just before the message that Xorg can't find any display devices
to use.

I also checked the xorg.conf file and it specifies to use the nvidia
driver, should I change it to the above driver or is the above driver
unique to Wayland?
The driver has nothing to do with Wayland as such. Clearly an Nvidia
driver isn't going to work with a non-Nvidia GPU, which is what your VM
has. If you're loading the Nvidia driver anyway, this may be the source
of the problem. Remove the Nvidia stuff and try again.

Kernel driver in use: vmwgfx

vmwgfx is VMWare guest GL driver

If it were nVidia it would read

Kernel driver in use: nvidia

I have tried removing the nvidia entries from the device group in xorg.conf, and, also specifying driver "vmware" instead of "nvidia", and in both cases Gnome and KDE can be started with Xorg. In both cases though they start with the wrong screen resolution relative to the resolution that the vmware player is using. Gnome under Wayland is capable of re-setting its resolution to match that of the vmware player when maximizing the player, but KDE is not capable of doing so under Wayland. I might have to play around with the resolution configuration parameters to try to get Xorg to set its resolution to match vmware's.

Putting the following section in xorg.conf caused Gnome under Xorg to start with the resolution of the Maximized vmware player, which was 1600x844, as desired. KDE did not start at the resolution of 1600x844, instead starting at 640x480, but the display configuration facility including 1600x844 as one of the resolutions it now provided, which then switched KDE into the desired resolution.
