Razer Blade 15 Base Model (Early 2020) Installation Log

This page is an installation log of gentoo linux on a Razer Blade 15 Base Model with an OLED. I won't go into detailed technical explanations in this log. I may drop a number of links which may eventually die and become inaccessible. I will however document everything that I've done, what worked well and what didn't. I will try to log everything in a neutral position as much as possible. I'll set my own requirements, and make my own choices. Some of which will most likely be wrong, so don't take this page as a Guide without asking for multiple opinions on it. If you find some problematic setup, don't hesitate to share it under the Discussions tab.

This is the product string I get from dmidecode:

user $dmidecode -s system-product-name

All the above worked fine, however I had to use a different key server ( to retrieve the public key from Gentoo Release Engineering. Found this domain on some random forum post. Booting the Razer was successful with the livecd prompt showing up.

Connecting to the Network

Basically followed the Network Guide, but this always fails on WIFI for various reasons. My network is under WPA-PSK, so I used net-setup and followed the setup wizard. This gave me an Unreachable Network problem, which I had to fix by adding the default gateway manually with:

root #route add default gw
I didn't need to install or deal with wpa_supplicant to have a connection initialized with net-setup

Creating the Partitions

LVM will be used on this laptop, so only 2 partitions are really needed: The standard EFI partition required for booting in UEFI mode and the actual Luks encrypted partition that will contain all other partitions.

root #fdisk /dev/nvme0n1

With fdisk, we create a new GPT partition table and dump whatever was there before (g). After, it's simply a matter of creating an EFI partition (n, default, default, +512M, t, 1) and then an extended Linux Filesystem partition. (n, default, default, default)

This is a log. Only do this if you don't want to dual boot
root #fdisk -l /dev/nvme0n1
Disk /dev/nvme0n1: 476.94 Gib, 512110190592 bytes, 1000215216 sectors
Disk model: NVMe CA5-8D512
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: gpt
Disk identifier: ...

Device           Start        End   Sectors   Size Type
/dev/nvme0n1p1    2048    1050623   1048576   512M EFI System
/dev/nvme0n1p2 1050624 1000215182 999164559 476.4G Linux filesystem

EFI Partition

Needs to be vfat according to the EFI System Partition Guide.

root #mkfs.vfat -F 32 /dev/nvme0n1p1

LUKS Partition

First step is to erase or randomize the disk data to avoid usage pattern attacks. Taken from Arch's DM-crypt Drive Preparation

root #cryptsetup open --type plain -d /dev/urandom /dev/nvme0n1p2 crypt-wipe
root #dd if=/dev/zero of=/dev/mapper/crypt-wipe status=progress
root #cryptsetup close crypt-wipe

Encryption scheme is chosen to match cryptsetup's default values:

root #cryptsetup luksFormat /dev/nvme0n1p2
This will overwrite data on /dev/nvme0n1p2 irrevocably.

Are you sure? (Type 'yes' in capital letters): YES
Enter passphrase for /dev/nvme0n1p2:
At this stage a simple passphrase is used to keep things simple. An encrypted key file will be added later.
root #cryptsetup luksOpen /dev/nvme0n1p2 gentoo
Enter passphrase for /dev/nvme0n1p2:

LVM Partitions

The LVM partitions created are: swap, /, /var, /var/log, /var/tmp, /home and a toy partition on /media

Format all partitions, XFS will be used for all /var reads/writes whereas the other file systems can just use EXT4:

root #mkswap -L "swap" /dev/mapper/vg0-swap
root #mkfs.ext4 -L "root" /dev/mapper/vg0-root
root #mkfs.ext4 -L "root" /dev/mapper/vg0-home
root #mkfs.ext4 -L "root" /dev/mapper/vg0-media
root #mkfs.xfs -l internal,size=128m -d agcount=2 /dev/mapper/vg0-var
root #mkfs.xfs -l internal,size=128m -d agcount=2 /dev/mapper/vg0-varlog
root #mkfs.xfs -l internal,size=128m -d agcount=2 /dev/mapper/vg0-vartmp

Installing Gentoo from Stage 3

Following the Handbook closely:

root #swapon -v /dev/mapper/vg0-swap
root #mount -v -t ext4 /dev/mapper/vg0-root /mnt/gentoo
root #mkdir -p /mnt/gentoo/var/{log,tmp}
root #mount -v -t xfs /dev/mapper/vg0-var /mnt/gentoo/var
root #mount -v -t xfs /dev/mapper/vg0-varlog /mnt/gentoo/var/log
root #mount -v -t xfs /dev/mapper/vg0-vartmp /mnt/gentoo/var/tmp
root #mkdir /mnt/gentoo/{boot,home,media}
root #mount /dev/nvme0n1p1 /mnt/gentoo/boot
root #mount -v -t ext4 /dev/mapper/vg0-home /mnt/gentoo/home
root #mount -v -t ext4 /dev/mapper/vg0-media /mnt/gentoo/media

Configuring make.conf

This is a minimal make.conf file:

FILE /etc/portage/make.conf
# These settings were set by the catalyst build script that automatically
# built this stage.
# Please consult /usr/share/portage/config/make.conf.example for a more
# detailed example.
COMMON_FLAGS="-march=skylake -O2 -pipe"
CPU_FLAGS_X86="aes avx avx2 f16c fma3 mmx mmxext pclmul popcnt rdrand sse sse2 sse3 sse4_1 sse4_2 ssse3"

# NOTE: This stage was built with the bindist Use flag enabled

# This sets the language of build output to English.
# Please keep this setting intact when reporting bugs.

I avoid setting USE flags globally. The only exception is X and this flag will be added later in the log. Notice I don't add VIDEO_CARDS or INPUT_DEVICES at this time either.
I accept all licenses, avoiding having to figure out license names individually or in groups.

Helper commands that I used:

root #grep -m1 -A3 "vendor_id" /proc/cpuinfo
vendor_id       : GenuineIntel
cpu family      : 6
model           : 165
model name      : Intel(R) Core(TM) i7-10750H CPU @ 2.60GHz

From Safe CFLAGS, that is -march=skylake

root #emerge --ask cpuid2cpuflags
root #cpuid2cpuflags
CPU_FLAGS_X86: aes avx avx2 f16c fma3 mmx mmxext pclmul popcnt rdrand sse sse2 sse3 sse4_1 sse4_2 ssse3

Chroot to /mnt/gentoo

Largely from the Installation Guide:

root #mirrorselect -i -o >> /mnt/gentoo/etc/portage/make.conf
root #mkdir -p /mnt/gentoo/etc/portage/repos.conf
root #cp /mnt/gentoo/usr/share/portage/config/repos.conf /mnt/gentoo/etc/portage/repos.conf/gentoo.conf
root #cp --dereference /etc/resolv.conf /mnt/gentoo/etc/

root #mount --rbind /sys /mnt/gentoo/sys
root #mount --rbind /dev/ /mnt/gentoo/dev
root #chroot /mnt/gentoo /bin/bash
root #source /etc/profile
First I picked an rsync mirror from the list, but below when doing the first sync, this would fail. So I had to redo the selection for an https address

There's no best way to configure a kernel, you have to immerse yourself with Linux and do some research. This is by no mean authoritative. I went on pure instinct, coming up with some search hits, and deciding whether it might be needed or useful. I start by what I know I'll need and remove what i know I won't.

By far the worst section of the kernel configuration. It's very difficult to keep up to date with Docker options, cgroups and most of the kernel work done here. You'll find that the article on Docker is mostly out of date as well. The best way of reaching this configuration is to emerge Docker and read the warnings on missing kernel options, once you've booted onto your new system.

Installing kernal, modules/firmware

Initially I had the intel-ishtp module under /etc/modules-load.d/ but that never went anywhere. Still unsure if the hardware I have supports this
(chroot) root #make && make modules_install
(chroot) root #make install
(chroot) root #emerge --ask sys-kernel/linux-firmware

Installing an initramfs

Requirement is still to have the LVM partition decrypted through a key file that is itself password protected but at this point, it was getting complicated, and hardly working. I backtracked and used an initramfs made with genkernel.
I also ran into an issue where a module was missing from initramfs at some point. The issue is that if you change the kernel repeatedly adding/removing options, then the initramfs should normally be recreated if there are any modules that it'll require to boot.
(chroot) root #emerge --ask sys-fs/lvm2
(chroot) root #rc-update add lvm boot
(chroot) root #emerge --ask sys-fs/cryptsetup
(chroot) root #genkernel --lvm --luks --install --kernel-config=/usr/src/linux/.config initramfs

Resizing /var

While using the system, it became obvious that I underestimated size requirements of /var. That's mainly because the legacy /usr/portage moved to /var/... I resized /media and re-allocated some space.

root #e2fsck -f /dev/mapper/vg0-media
root #resize2fs /dev/mapper/vg0-media 290G
root #lvreduce -L 290G /dev/mapper/vg0-media
