[LINUX] Building the strongest environment after introducing Manjaro to Dell XPS 15


Based on the fact that Manjaro installation and basic settings have been completed, this is a memorandum of subsequent settings. Please refer to others for installation etc. Assuming the Dell XPS15 7590 model. Please let me know if there is a better setting. Also, update accordingly.

As a background, I got a MacBook Pro and a Dell XPS15 7590 on my work machine, but I had a MacBook Pro as my main development machine, but last night I had a problem that keyboard did not work, so I got it with a repair program Since I will be away from the Dell machine, I hurriedly put the Dell machine in the development environment. This time, I made a note of the settings that I tend to forget after putting Manjaro in the XPS 15 7590. By the way, my Linux history is about 20 years +, and my personal distro itinerary is Redhat => Ubuntu => Mint => Manjaro => Archlinux => Manjaro (here and now), but I still don't know anything. .. Akan. .. Linux has a high degree of freedom, so you can customize it in various ways, but if you stick to the GUI, dozens of hours of precious time will melt, so if you are not careful, you will be abandoned like me because of your main business. Absolutely no Conky.

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)


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 **


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! screenshot.png

Compile options

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


$ 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.


CFLAGS="-march=skylake -O2 -pipe"

Automatic key addition


keyserver-options auto-key-retrieve
auto-key-locate hkp://pool.sks-keyservers.net

Settings for PKG BUILDS

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


$ 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 こんなロゴ


$ 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



Then compile


$ makepkg -s

Install the finished package


$ tree -sh

Library build

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


$ 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

$ fc-cache -f -v

zsh settings

In the past, I added it by referring to the pages of various smart people, but since there are various machines and I want to reduce environment dependence as much as possible, I will omit it as much as possible and keep it simple. ..

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


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



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


$ vim +PluginInstall +qall 

Then it looks like this Screenshot_2020-04-05_15-27-06.png

plank settings

After all, Dock is convenient. So I set it up quickly. Auto start setting

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
  4. Delete unnecessary X-based config files that have been tampered with so far


$ sudo mhwd -li #List of installed drivers
$ sudo mhwd -r xxx #Driver removal
$ 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

And after entering the settings, restart

Touchpad related

Make it possible to swipe with Touchpad or like a Mac. There is a developer description on Github, so if you want to know more, go there


$ sudo pacman -S xdotool wmctrl libinput-gestures libinput-gestures-setup
$ sudo gpasswd -a $USER input

$ sudo libinput list-devices
$ libinput-gestures-setup autostart
$ libinput-gestures-setup start

Then, create a mapping file. The following is changed according to your WM environment.


gesture swipe up    3 xdotool key ctrl+alt+d
gesture swipe down  3 xdotool key alt+Shift+Tab
gesture swipe left  3 xdotool key ctrl+Tab
gesture swipe right 3 xdotool key ctrl+Shift+Tab

After that, it will be enabled by restarting the service or logging in again.

Scanner related

I am using EPSON EP-882A. Scanning via Network is also OK below


$ avahi-browse --all -t -r #IP search with Network scan
$ yay imagescan imagescan-plugin-networkscan 

And if you put the IP of the scanner in the configuration file, you can also scan via Network


dev2.udi    = esci:networkscan:// #IP is above avahi-Browse for scanner
dev2.model  = EP-882A
dev2.vendor = EPSON

Now, hit utsushi from the terminal to launch the front-end scanner app. Since it is not displayed in the Xface menu, enter the following settings

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.

I will measure the speed. With speedtest-cli, you can check it with one command from the terminal, which is convenient. Bandwidth is crowded at the time of measurement, it is a little slow
