This guide assumes you have a freshly-installed Ubuntu 18.04 installed on your Dell G3. Following the following steps will recreate the configuration that Dell ships on Ubuntu-preinstalled G3 laptops.

You have to make sure to get a recovery disk before making these changes.
Dell OEM customizations
Dell does quite a few modifications to Ubuntu official 16.04 ISO. This is a non-exhaustive list of what Dell changed. Please note that there is no solution yet to make the Goodix fingerprint sensor works.
Dell customizations that can be skipped
- Bluez 5.37: Bluez 5.48 is default in Ubuntu 18.04,
- Dell e-star (
dell-e-star_0.05_all.deb): e-star logo in unity control panel,
- Dell Super key (
Superkeyboard key (the one with Windows logo) with a gschema1,
- Google Chrome (
google-chrome-stable_64.0.3282.140-1_amd64.deb): can be installed easily,
- Add Google Chrome to launcher (
oem-add-google-chrome-to-launcher_1_all.deb): add Google Chrome to Ubuntu desktop launcher with a gschema1,
- A more recent Mesa (libdrm 2.4.83-1): 2.4.91-2 is default in Ubuntu 18.04,
- Dell blacklists
psmousekernel module to remove some warning in kernel logs.
- Dell EULA (
dell-eula_1.03_all.deb): useless information,
- Dell repository: useless for this specific laptop.
In the package
config-prime-select-intel-all_0.15_all.deb, Dell ships a config file to make Ubuntu
announces itself as
Linux-Dell-Video to the ACPI BIOS.
To do the same without a Debian package, create
/etc/default/grub.d/Linux-Dell-Video.cfg and write:
Then update GRUB configuration by executing in a shell:
Better battery life
Dell uses TLP to manage power consumption and to preserve battery life.
To get the same config as the one Dell ships, install
tlp-rdw then reboot.
Dell also includes a custom TLP configuration
tlp-sensible_1.1_all.deb but it is useless with recent versions of Ubuntu.
r8168-dkms and reboot to get a fully-working ethernet card.
Dell ships Ubuntu 16.04 with a preconfigured Optimus-ready (PRIME) Nvidia driver and CUDA. It uses Nvidia 390.25 driver that is older those available in Ubuntu 18.04. The way Optimus works in Ubuntu 18.04 changed a lot and now installing a recent Nvidia driver will be sufficient to get a working setup.
You can use
ppa:graphics-drivers/ppa to have newer Nvidia drivers.
Before november 2018, the only way to get a proper PRIME support was to follow the instructions on Tim Richardson’s Prime-Ubuntu-18.04 project. This has been fixed in Ubuntu 18.10 and backported in 18.04.
Tear free screen with Nvidia PRIME
To use PRIME-sync and remove tearing, create
/etc/default/grub.d/Nvidia-DRM.cfg and write:
This will load Nvidia at boot enabling some experimental features that might create instability. I have been using this configuration so far and I had no issues with Xorg.
Make sure you are running a kernel newer than 4.17 to make Linux will announce itself compatible with native Thunderbolt to the UEFI. You can upgrade to a newer kernel using Ubuntu LTS Enablement Stack:
