Installing Gentoo On A Alienware 17 R1

The Alienware family is IMO a nice desktop replacement where space is scarce. Ive bought a used one in great shape.

Pros

Great extensibility
Great connectivity
Good processing quality

Cons

Heavy weight

Installation

Note	These are raw notes taken from my installation. Depending on your setup things may be different. Because I am not a gentoo expert there are surely better ways of doing this or that ;)

Preparartion

Follow the instructions from:

https://wiki.gentoo.org/wiki/Handbook:AMD64

I used a Linux Mint Live USB-Stick to boot the system for installation

Disk Partitioning

Note	Later I added an additional 1TB drive that caused drive identifiers to change

Kernel

Note

This is definitely not the best idea because a live CD kernel config includes everything (that means lots of modules) that are only necessary for a live CD. The system thats going to be installed only needs a small fraction of them. I would recommend to either use genkernel or step through the config manually

emerge --ask sys-kernel/gentoo-sources
emerge -av sys-apps/pciutils

use kernel config from mint live cd as base:

cp /boot/config-4.10.0-38-generic /mnt/gentoo/opt/
make menuconfig

load /opt/config-4.10.0-38-generic and save as .config

make -j8 && make modules_install
make install

To import images from a camera, plug it in, change to the image import directory, and run

$ mkdir pics && cd $_
$ gphoto2 --get-all-files

Update The System

Update The Kernel

make olddefconfig

Generates a new configuration with default values from the ARCH supplied defconfig file while, at the same time, maintaining all the previous options set in the .config file found at /usr/src/linux/.config. This is a fast and safe method for upgrading a config file that has all the configuration options it needs for hardware support while at the same time gaining bug fixes and security patches.

Use emerge -av meld to compare old/new kernel .config

emerge -av --update --deep --with-bdeps=y --newuse sys-kernel/gentoo-sources
# your old kernel-config is here
ls /usr/src/linux/.config
# this is your new kernel
cd /usr/src/linux-4.19.66-gentoo
make olddefconfig
# quick check the differences
meld .config /usr/src/linux/.config
# set your new kernel
eselect kernel list
eselect kernel set 1
# compile
make modules_prepare
make -j8
make modules_install
make install
emerge -av @module-rebuild

I recommend installing sys-boot/os-prober if you have other systems installed

emerge --ask --newuse sys-boot/os-prober

Whenever a new kernel is installed, GRUB2 must be reconfigured to recognize it

grub-mkconfig -o /boot/grub/grub.cfg

The new kernel should now be added to the bootloader. Before rebooting check the configuration generated by grub-mkconfig. If the new kernel is not the default set it with GRUB_DEFAULT=X

vim /boot/grub/grub.cfg
grep gnulinux /boot/grub/grub.cfg
# set #GRUB_DEFAULT=2
vim /etc/default/grub

Here is the current config I use on this system (still improving ;)

.config

Troubleshooting

If the new kernel fails to boot and the error messages tell you something about cannot mount root fs or anything regarding filesystems, you most likely have forgotten to:

compile the SATA controller device drivers not as module (*)
compile the root filesystem not as module (*)

grep -i btrfs /usr/src/linux/.config
CONFIG_BTRFS_FS=y
...

grep -i sata /usr/src/linux/.config
CONFIG_SATA_AHCI=y
...

# go back to cd /usr/src/linux and
make menuconfig

Managing Licenes

To accept all licenses add to @/etc/portage/make.conf@

ACCEPT_LICENSE="*"

For per package control use @etc/portage/package.license@
