Burned ubuntu-19.10-preinstalled-server-arm64+raspi3.img.xz. First boot on RaspberryPi 4 looked ok until it hung after
[ OK ] Reached target Cloud-init target.
Power cycled, and boot ended with
Ubuntu 19.10 ubuntu tty
Ubuntu login: [ 23.431015] cloud-initâ¦
Then no response to keyboard input, in USB2 or 3 port. The same procedure worked fine (successful login, etc) on first boot with a RaspberryPi 3.

Set total_mem=3072 in /boot/firmware/usercfg.txt
(If you mount the sd card in another computer, the usercfg.txt is on the small vfat partition.)
