Dell Precision 3470
This article is a work in progress as I manage thru the installation and initial setup. Please add from your experience.

Look at the troubleshooting section for info about installation media not loading.
For installation use kernel 6.1 and above (the 5.15) doesn't work. In order to do so, it is necessary at this time (January 4th, 2 3) to use the testing package. In order to do so add the ~amd64 keyword to the relevant packages. If using distribution kernel one can do so by creating the following file:
~sys-kernel/gentoo-kernel-6.1.2 ~amd64 ~sys-kernel/dist-kernel-6.1.2 ~amd64
In order to get the framebuffer working at the earliest time possible (necessary for example if using encrypted LUKS root partition), you should enable the EFI framebuffer support:
Device Drivers ->Graphics support ->Frame buffer Devices ->Support for frame buffer devices [y] ->EFI-based Framebuffer Support [y]
Alternatively, if you use the distribution kernel, you can create the following file to add the option:
#EFI framebuffer support CONFIG_FB_EFI=y
(Optional section. If the platform requires any user space packages or kernel patches, mention them here).
emerge --ask category/package
In order to boot the Gentoo installation media, first you need to disable secure boot.
Make sure to run appropriate service according to Bluetooth:
rc-service bluetooth start
rc-update add bluetooth default
Fprintd does not recognize the fingerprint reader out of the box.
It seems that Ubuntu has a propriety driver for this fingerprint reader.
Intel video driver with <=5.15 kernel
Using distribution kernel version 5.15 result in video freeze due to incompatible Intel display driver. One should use kernel 6.1 from testing. As long as kernel 6.1 is in testing, this can be done by adding the ~amd64 keyword prior to emerging the kernel. If the Gentoo liveUSB is used for the installation, it also sometimes freezes during loading. If that the case, either try again (for some reason this is not consistent with the liveUSB unlike with the install) or use a different distro liveUSB for the installation.
Xorg fails on boot but works later
This is due to a race condition while loading the kernel modules and Xorg. Please add the i915 driver to the initramsfs.
force_drivers+=" i915 "
Regenerate the initramfs image:
Please see NVIDIA/Optimus.
