Debian and Ubuntu VMs not working properly

[Flashbin]

So I've been wanting to install a PiHole in my Network, but because it's not directly supported on FreeNAS, I tought i could try to install Ubuntu Server or Debian in a VM. So after countless tries, here are my problems:

• debian-9.11.0-amd64-netinst.iso will boot, but the screen is always a garbled mess (see screenshot). I've tried giving it more RAM. I've tried many different VNC viewers.

• ubuntu-18.04.3-live-server-amd64.iso will boot properly, but even after selecting the right keyboard layout, keys appear on random spots where they shoudn't ever be. E.g. the number 4 will be next to the enter key, whereas other keys won't do anything. Impossible to even adjust the IP configuration, because I cant find the "/". Again, I've tried multiple VNC viewers without success.

I've tried this on 11.2-U7 and 11.3-RELEASE, but both produce the same problems.

My hardware:
MB: Dell 0KWVT8
CPU: i7-4770
RAM: 16GB non-ECC

The issue is the resolution. I believe you need to set it to 800*600 under the VNC options, I think.

Thank you for the quick response, but I'm not sure how I could do that. In RealVNC and ThightVNC, there's only scale, which is set to 100%/auto.

For Debian:
Go in the "Virtual Machine" menu.
Debian VM should be in the OFF state.
Press the "3 vertical dots" on the same line as Debian VM and select "Devices".
On the "VNC" line, select the "3 vertical dots" and select "Edit".
Change "Resolution" to 800x600, save and then you can start your Debian VM. Display should now be readable.

Thank you very much, this solved it!

If using VNC regularly you might want to consider using x2go.
