No graphical / lightdm boot on Lubuntu 18.04?

I'm able to get graphics up on the initial installation phase of Lubuntu 18.04, however after the system installs it doesn't seem to start up lightdm or xorg at all - no graphics, just console. Any idea as to what might be going on here that's preventing it from starting?

I was able to install other Linux distros such as q4os and get the graphical interface up just fine, but Lubuntu is proving to be a real hassle.
Its a known issue/bug on Ubuntu, hopefully they include the fix soon.

the easy workaround:
=> Change the virtual graphic card to "VirtIO-GPU" or to "vmware" or use SPICE.
Interesting, there is no "VirtIO-GPU" in Hardware -> Display:

But "VMware compatible" does get it going...
So while VMware compatible does work on 18.04, when I try Lubuntu 19.04 beta the system hangs at:
[drm:vmw_driver_load.cold.19 [vmwgfx]] *ERROR* Hardware has no pitchlock
Strange, I am running Proxmox 5.3 already... but I think I just figured out the issue. Since I'm not an enterprise user I would need to disable the enterprise repository and add the non-subscription repo, is that correct?

Ie, to `/etc/apt/sources.list` add:
# PVE pve-no-subscription repository provided by,
# NOT recommended for production use
deb stretch pve-no-subscription

Then `apt update && apt dist-upgrade`. I suspect when I do this things will work as you're explaining...
So after the update as per above and a reboot I'm unfortunately still hitting this black screen on 19.04. Hmm.
