Bios setup
- have to disable Raid ... Enable AHCI
- Disable secure boot in bios to permit Hibernate
in case you wanted to change zpool passwd
$ zfs change-key rpool
create swap partition to permit Hibernate
create a swap partition right sized for hibernation.
add theses 2 lines in : /usr/share/ubiquity/zsys-setup
MEMSIZE=$(cat /proc/meminfo | grep MemTotal | awk -F' ' '{print $2}')
SWAPVOLSIZE=$(( MEMSIZE / 1024 ))
like bellow :
# Convert to MiB to align the size on the size of a block
SWAPVOLSIZE=$(( SWAPSIZE / 1024 / 1024 ))
MEMSIZE=$(cat /proc/meminfo | grep MemTotal | awk -F' ' '{print $2}')
SWAPVOLSIZE=$(( MEMSIZE / 1024 ))
prepare_target "${TARGET}"
format_disk "${DISK}" "${PARTBASE}" "${PARTESP}" "${PARTBPOOL}" "${PARTRPOOL}" "${SWAPVOLSIZE}"
init_zfs "${TARGET}" "${DISK}${PARTBASE}${PARTBPOOL}" "${DISK}${PARTBASE}${PARTRPOOL}"
init_system_partitions "${TARGET}" "${DISK}${PARTBASE}1" "${DISK}${PARTBASE}${PARTESP}"
Run ubiquity to start the installer and install as normal, selecting “Use entire disk” and the option to use ZFS.

console grub ...
Boot menu uses a tiny font (GRUB menu).
Best way to address this would be to have GRUB automatically select the right font, but GRUB is kept small on purpose, or to install a larger GRUB font when installing Ubuntu.
Workaround: let the default GRUB terminal driver, gfxterm, switch to a supported mode such as 1600x1200 (NB to list video modes, disable secure mode in the BIOS and run the videoinfo command in the GRUB shell accessed by pressing "c" from the GRUB menu):
GRUB_GFXMODE=1280x1024
update-grub
Splash screen uses too small logo and somewhat too small fonts (Plymouth).
Plymouth has logic to detect the proper scaling to apply, but it's still too small; workaround by forcing the scale on the kernel cmdline:
Add to GRUB_CMDLINE_LINUX in /etc/default/grub.
plymouth.force-scale=3
update-grub
Console terminal uses too small fonts.
Note that the package shipping the Ubuntu Monospace font for the terminal, fonts-ubuntu-console, is not installed by default and only ships 8x16 fonts.
Change the font by running :
dpkg-reconfigure console-setup
select a font face that supports a larger font size, for instance the Terminus font, and select a large font size such as 16x32; you need to reboot for the new font to be set.
activate hibernation in system
Disable secure boot in bios to permit Hibernate.
apt install pm-utils
update-initramfs -u -k $(uname -r)
pm-hibernate
printf "RESUME=UUID=$(blkid | awk -F\" '/swap/ {print $2}')\n" | head -n 1| sudo tee /etc/initramfs-tools/conf.d/resume
you can check with : blkid
update-initramfs -u -k all
change /etc/default/grub : add your resume UUID into GRUB_CMDLINE_LINUX_DEFAULT
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash resume=UUID=75034ff5-...-9e4564e16d34"

configure hibernate to auto switch from sleep to hibernate
edit : /etc/systemd/sleep.conf
And add this value to it (The number represents seconds you want to pass in sleep, after which the computer will switch to hibernation, so you can put it in 60 seconds or something short just to check it's working and after that you can put whatever ammount of time you want):
[Sleep]
HibernateDelaySec=7200
