Installation
Start with Try Ubuntu…
Install Ubuntu on encrypted BTRFS volume. This type of installation make 2 subvolumens: @ and @home. They are mounted on / and /home. We need to make other subvolumes before restart and edit /etc/fstab on new system with hardening and SSD optimization options.
Custom partitioning and BTRFS installation.
| Part | Size | Mount point | type |
|---|---|---|---|
| 1 | 512M | /boot/efi | EFI |
| 2 | 2048G | /boot | ext4 |
| 3 | ~500G | LUKS crypt |
| Subvolume | Mount point |
|---|---|
| @ | / |
| @home | /home |
Post installation – add more subvolumes to match this schema.
/dev/mapper/nvme1n1p3_crypt – BTRFS subvolumes
| Subvolume | Mount point |
|---|---|
| @ | / |
| @home | /home |
| @opt | /opt |
| @var | /var |
| @var_log | /var/log |
| @var_log_audit | /var/log/audit |
| @var_tmp | /var/tmp |
| @backup | /var |
Create BTRFS subvolumes.
mount /dev/mapper/nvme1n1p3_crypt /mnt
cd /mnt
btrfs subvolume create @opt
btrfs subvolume create @var
btrfs subvolume create @var_log
btrfs subvolume create @var_log_audit
btrfs subvolume create @var_tmp
btrfs subvolume create @backup
Move files to new subvolumes.
umount /mnt
mount -o subvol=@,ssd,noatime,space_cache,commit=120,compress=zstd /dev/mapper/nvme1n1p3_crypt /mnt
mount -o subvol=@home,ssd,noatime,space_cache,commit=120,compress=zstd /dev/mapper/nvme1n1p3_crypt /mnt/home
mkdir /mnt/var2
mount -o subvol=@var,ssd,noatime,space_cache,commit=120,compress=zstd /dev/mapper/nvme1n1p3_crypt /mnt/var2
mv /mnt/var/* /mnt/var2/
mkdir /mnt/var2/log2
mount -o subvol=@var_log,ssd,noatime,space_cache,commit=120,compress=zstd /dev/mapper/nvme1n1p3_crypt /mnt/var2/log2
mv /mnt/var2/log/* /mnt/var2/log2/
Edit /mnt/etc/fstab to match your UUID and partitions.

Now reboot.
Configuration
Nvidia
Install Nvidia proprietary driver.
sudo ubuntu-drivers autoinstall
Now we can use hybrid (Prime) setup.
Power Management
To save power use integrated Intel GPU. In Nvidia configuration select “Nvidia (on-demand)” or Intel.
tlp
Install tlp tlp-rdw
sudo apt install tlp tlp-rdw
sudo reboot
powertop
Install powertop.
sudo apt install powertop
Calibration to prevent inaccurate measurement
Note: Calibration will toggle various functions like backlight or wifi. Thus, it may turn your screen black for some time, lose your connection, and so on. Do not touch the machine during the calibration.
powertop -c
