The specifications of XPS15 7590 have been improved with the following hardware. It is quite the strongest at the moment. I use it by connecting it to Eizo's external LCD. 12 cores are used up, but there is still plenty of memory. If I port it to Docker or something from now on, I think it will be used up. The number of cores may be the bottleneck. By the way, the specs are good even if it is improved to a new one, but the power consumption is high, and if you run various applications you are developing, the battery will run out in about 3 hours. .. --Storage: 1TB (1TB PCIe NVMe M.2) --Memory: 64GB (PC4-21300 DDR4-2666 32GBx2)

Self-discipline

The work client machine, so as not to melt the time --Do not customize the GUI. Especially ** Conky ** is dangerous --Don't mess around with the kernel. Especially ** vanilla ** is dangerous --Use the default app mainly --Distro Doesn't shift. Especially ** Archlinux ** is dangerous --Back up as appropriate with timeshift-launcher --Prepare Boot USB just in case. Especially when playing around ** X **

desktop

So, for now, the desktop looks like this. I want to make my desktop gorgeous with Conky, but I'm holding back. The company's Google Drive is always connected by Stream using Fuse, the development machine is also mounted from the Thunar shortcut and easy to handle, and there is no complaint with visual studio code over ssh! The external display of EIZO can be used without any problem, which is wonderful!

Compile options

With makepkg, set up to compile to the best package for your machine.

terminal

$ sudo vim /etc/makepkg.conf

Please refer to the Gentoo Wiki for detailed option explanations. Refer to here for the architecture name. To put it simply, setting the O flag to 3 or more has no effect. 2 is recommended.

-O flag: This controls the overall optimization level, but especially by increasing this optimization level, the source code will take some time to compile and will use more memory. ..

-pipe flag: This flag has no effect on the generated binaries themselves, but it reduces compile time. This tells you to use a pipe instead of a temporary file between each process in compilation. This will use a lot of memory. For systems with insufficient memory, GCC may be killed. Do not use this flag in such cases.

/etc/makepkg.conf

CFLAGS="-march=skylake -O2 -pipe"
CXXFLAGS=${CFLAGS}
MAKEFLAGS="-j$(($(nproc)+1))"
PACKAGER="<Name>"`

Settings for PKG BUILDS

Set to be asked to overwrite PKG BUILDS when installing via yay

terminal

$ yay --editmenu --nodiffmenu --save

Custom kernel installation

For example, if you want to put in a custom kernel [^ 1], it looks like this. This time, install xanmod. However, there are cases where the original Manjaro is faster, so it is not necessary to install a custom kernel so much, but if you have time to play, please [^ 1]: Be careful of getting stuck

terminal

$ mkdir -p ~/opt/src #Create folder for build
$ cd ~/opt/src #Move to build folder
$ yay -G linux-xanmod #xanmod kernel download
$ cd linux-xanmod #Move to folder

And change the parameters according to the microarchitecture

~/opt/src/linux-xanmod/PKGBUILDS

_microarchitecture=42

Then compile

terminal

$ makepkg -s

Install the finished package

terminal

$ tree -sh

Library build

Create a package that suits your architecture and try to optimize it.

terminal

$ cd ~/opt/src
$ yay -G glibc
$ cd glibc
$ makepkg -si 

Download the source with the above pattern (yay -G), build and install the following library / app

atom dropbox glibc gtk2 gtkmm3 libglademm chromium glade gtk3 libglade libxml2

Required package installation

A package to put in with pacman. Here and there, you can use whatever you need.

terminal

$ sudo pacman -Syu yay vim wget curl atom fcitx-im fcitx-mozc fcitx-configtool jq sysstat plank unrar p7zip unarchiver

vim settings

Simple settings such as vim's Gruvbox schema. It seems that there are various package managers, but for the time being, at the major Vundle

terminal

$ mkdir -p .vim
$ git clone https://github.com/VundleVim/Vundle.vim.git ~/.vim/bundle/Vundle.vim

Setting

~/.vimrc

set nocompatible
filetype off
set rtp+=~/.vim/bundle/Vundle.vim
call vundle#begin()

Plugin 'VundleVim/Vundle.vim'

"The plugins you want to install are listed below
" Plugin '[Github Author]/[Github repo]'Fill in in the format of
Plugin 'airblade/vim-gitgutter'
Plugin 'morhetz/gruvbox'

call vundle#end()
filetype plugin indent on

"Write other custom settings below
syntax enable
set background=dark
colorscheme gruvbox

Run

$ vim +PluginInstall +qall

Nvidia Driver This is the part I was most addicted to. There are many ways to do it on the web, and the only one I've tried to get the nvidia driver working. I've spent dozens of hours. ..

1. Remove the nvidia driver if it is installed
2. Install nvidia driver
3. prime installation

$ sudo mhwd -i pci video-nvidia-440xx #Driver installation
$ sudo pacman -S nvidia-prime
# /etc/X11/xorg.conf.d/Or/etc/modprobe.d/Delete X-related configuration files in

WiFi There is a Mac with the same environment at about 200 Mbps, but this child is about 40 Mbps. There are various threads that the XPS WiFi module and Linux are not compatible, but communication is stable, so that's enough. But I wondered if there would be a little more. The following is what I tried. So far, there is only a change that seems to be a little faster. .. I'd like to investigate and try a method to find the cause, but I'm busy with work, so for the time being, this is it.

Once I pointed to NVMe on Windows and measured the speed with the latest Windows driver, I found that it was only about the same speed, so I found that this was probably the limit of the chip, so for the time being WiFi This is related.
