Recently Grub has been changing to a high resolution mode. On some systems this is really slow, presumably due to having a crap BIOS. On kvm/qemu systems it doesn't work with -display curses.
How do I get grub to stick to 80x25 text?

I decided my home Linux server had been through too many LTS upgrades, and
did a fresh install of Ubuntu Server 18.04.
The old /etc/network/interfaces.d system has been replaced by netplan and
I was able to configure a bridge device and attach ethernet devices, but
setting the MTU doesn't work. (I have the MTU configured in netplan for
both the ethernet device and the bridge device)
I managed to hack in a workaround by making a networkd-dispatcher script
(routable.d) that calls `ip link set mtu ...`, but wondered if there's a
proper way to make this work on netplan?
My problem is that I cannot get the ethernet card on the local network to get up. I'm new to debian after many years of red-hat/fedora. The machine: HP Compaq Elite 8300 SFF (Core i5). The system: debian buster (testing)

The eno1 is onboard, connected to adsl and works fine. If I restart the network with 'systemctl restart networking', or, './etc/init.d/networking restart', the network goes down and fails.
The enp3s0 is connected to a switch on a local network which has two other fedora computers on it. With a previous debian box all I did to have it work on this network was write the following config, reboot, and it worked. I was guided by https://www.debian.org/doc/manuals/debian-reference/ch05. That old box went bung, so I acquired the current one and tried the same config, with the appropriate name changes. That config is in /etc/interfaces (which I created on this machine):
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
# The loopback network interface
iface lo inet loopback
# The primary network interface
iface eno1 inet dhcp
# This is an autoconfigured IPv6 interface
iface eno1 inet6 auto
# local net
iface enp3s0 inet static
There is no /etc/network/interfaces.d/ on this machine. And this particular ethernet card is the same one that worked in previous debian box.
Here are the commands I've used, but none has succeeded in getting the card up, though the ip address was assigned and shown in the 'ip addr' output. There were no error messages other than "FAILED" in the systemctl status output.
ip addr add 192.168.0.3 dev enp3s0
ip addr add 192.168.0.3/24 dev enp3s0
ip link set enp3s0 up
I was hoping for some help to let me know what I need to do to get this ethernet working?
