Exploring with Gentoo Linux (Part 2)

Part 2 - Configuring Other Applications

Git:

Git is distributed revision control and source code management software. I need to install git first because I have dotfiles and config files for the applications I need. # emerge --ask dev-vcs/git

After the installation, following config settings need to be done at least.$ git config --global user.name "my_username" $ git config --global user.email "my_email"

Then, download the dotfiles from Github.$ cd ~/ $ git clone https://github.com/ubyt3m3/dotfiles.git ... $ ls dotfiles

st:

st is a simpke terminal for X. I use this terminal until I finish setting up urxvt. savedconfig USE flag lets you save a customized configuration file to /etc/portage/savedconfig/x11-terms/st.# echo "x11-terms/st savedconfig" > /etc/portage/package.use/st # emerge --ask x11-terms/st

Rxvt-unicode:

Rxvt-unicode (urxvt) is THE terminal emulator that I must have in my work environment since OpenBox days. It's fast, lean, highly customizable and can display different fonts. I have another post regarding how I customize it.

Gentoo Linux allows you to choose what options to enable or disable using the USE flags. The options I wanted to enable were the followings:

  • 256-color: Enable 256 color support
  • unicode3: Use 21 instead of 16 bits to represent unicode characters
  • xft: Build with support for XFT font renderer (x11-libs/libXft)
  • gdk-pixbuf: Build with support for image loading and manipulation. Need this for image previewing in ranger

There are a few ways to do this in Gentoo. Since I wanted to do per package base, I set it in the /etc/portage/package.use/ directory:# echo "x11-terms/rxvt-unicode 256-color unicode3 xft gdk-pixbuf" > /etc/portage/package.use/rxvt-unicode # emerge --ask x11-terms/rxvt-unicode or set it during the installation:# USE="256-color unicode3 xft gdk-pixbuf" emerge --ask x11-terms/rxvt-unicode

Its config file is ~/.Xresources.

Neovim:

Neovim is a fork of Vim that promised to fix issues with Vim and provide a better out-of-the-box experience for Vim users. It also includs a built in terminal emulator.

Installation is simple.# emerge --ask app-editors/neovim

Its configuration file is in ~/.config/nvim/init.vim and I use vim-plug plug-in to handle installation of other plug-ins. Once my init.vim is copied to its config directory, run nvim. It should install defined plug-ins automatically. If it doesn't, go into the Normal/Command mode by hitting Esc. Then type :PlugInstall. This should trigger installation of plug-ins.

PCManFM:

PCManFM is a GUI file manager. It's light weight and has features like displaying mounted drives and dual panes. I don't usually use it but it's good to have as a backup.# emerge --ask x11-misc/pcmanfm

Faenza Icons and gtk2 theme:

Faenza is an icon theme for Gnome. I've looked around and liked it the most. It can be installed from Portage. # emerge --ask x11-themes/faenza-icon-theme

Icons and GTK2 theme can be applied from lxappearance, but it needs to be installed first. # emerge --ask lxde-base/lxappearance

My customized Morning Glory needs to be extracted to ~/.themes/.$ tar -xzvf MorningGlory.tar.gz -C ~/.themes/

Once the icons and theme have been prep'ed, run lxappearance to apply them.

For the theme, click on the Widget tab. Morning Glory should be listed in the left pane.

Icons

For the icon theme, click on the Icon Theme tab, and choose Faenza from the list in the left pane.

Ranger:

Ranger is a text-based file manager. The best feature for me is the vi-style keybinding. # emerge --ask app-misc/ranger

The default directory is ~/.config/ranger/ and you can copy the default configuration files to this directory.$ ranger --copy-config=all

Copied files are the followings:

  • rc.conf - startup commands and key bindings
  • commands.py - commands which are launched with :
  • rifle.conf - applications used when a given type of file is launched.

For image preview, w3m needs to be installed.# emerge --ask www-client/w3m

Then, enable image preview in ranger's config file, ~/.config/ranger/rc.conf.$ nvim ~/.config/ranger/rc.conf ================================== ... set preview_image true ... set preview_images_method urxvt

Cmus:

Cmus is a small, fast and powerful console music player. # emerge --ask media-sound/cmus

TO DOs: set ups

Scrot:

Scrot is a command line screen capture utility.# emerge --ask media-gfx/scrot

Neofetch:

Neofetch is a bash script that displays the system information such as installed OS, kernel version, CPU, memory, etc... next to an ASCII operating system logo.# emerge --ask app-misc/neofetch

Chromium

Chromium is a free and open-source web browser from Google. It features a minimal user interface, powerful web development tools, and a built in task manager. There is a proprietary version of browser called Google Chrome

with more features than Chromium.# emerge --ask www-client/chromium

Be warned: Compiling Chromium can take a significant amount of CPU time and system memory, and it took nearly 7 hours to complete compiling.

Fonts:

I use following fonts for urxvt and i3.

  • Inconsolata
  • Kochi (for Japanese)
  • Font Awesome (for font icons)
  • Deja Vu
# emerge --ask media-fonts/inconsolata # emerge --ask media-fonts/kochi-substitute # emerge --ask media-fonts/fontawesome # emerge --ask media-fonts/dejavu

That's all!

Exploring with Gentoo Linux (Part 1)

Part 1 - Base System

In my previous post, I mentioned that my 10-year-old PC went haywire and upgraded some components to fix them. One of them was the main hard disk that had Slackware installed. I replaced it with a new SSD disk, hoping to get some speed in processing (my PC was so old that I'm not expecting much of speed boost). Since my primary drive needed a replacement, I had to install new OS on it. I was thinking of putting Slackware as usual but it got me thinking a bit. Its last release was 4 years ago. I love its simplicity and stable build but didn't feel like installing a 4-year-old OS.

Gentoo Linux

I've tried Debian, Arch, and Manjaro Linux before, but I always came back to Slackware before I knew it. While debating whether to put Slackware 14.2 again, I came across with Gentoo Linux. I knew the existance of Gentoo Linux and you'd need to compile every package, like Ports in FreeBSD. Well, I wanted to start a new so I decided to give it a try to see how I'd like it.

Disclaimer:
The information in this site is the result of my researches in the Internet and of my experiences. This information below is solely used for my purpose and may not be suitable for others.

Installation:

I wanted the set up of my work environment be the same as what I had before (See Building My Work Environment (Part 1)), so most of applications that'll be installed will be the same. At any rate, the installation of Gentoo was a bit of trial and error, and it took quite a while to get it installed. I'll leave the steps to its Handbook, but its installation procedure is not a menu driven, like other distos. It involes a lot of typings. It reminded me of the Arch Linux installation.

Even Slackware installation is a console menu based, so that makes a big difference between these two distros. I would think the installation procedure for Gentoo or Arch is more flexible.

Partition/filesystem Schemes:

I have this 256GB SSD as a primary disk and 1TB SATA disk for /home. The SSD disk was brand new so I partitioned it as follows with parted;

PartitionSizeFSDescription
/dev/sda12MiB-BIOS boot partition
/dev/sda2128MiBext2Boot partition
/dev/sda34295MiBSWAPSwap Partition
/dev/sda4239970MiBext4/ Partition

For the secondary disk, I converted its partition table to gpt and created one partition for /home.

PartitionSizeFSDescription
/dev/sdb1953868MiBext4/home partition

This below is my /etc/fstab. I have /var/tmp and /var/tmp/portage as tmpfs. I took an advice from Portage TMPDIR on tmpfs in Gentoo wiki.

/dev/sda2/bootext2defaults,noatime0 2
/dev/sda3noneswapsw0 0
/dev/sda4/ext4noatime,errors=remount-ro0 1
/dev/sdb1/homeext4defaults1 2
tmpfs/tmptmpfsnoatime,nodev,nosuid,size=10G0 0
tmpfs/var/tmptmpfsrw,nosuid,noatime,nodev, size=10G,mode=17770 0
tmpfs/var/tmp/portage tmpfsrw,nosuid,noatime,nodev,size=10G, mode=775,uid=portage,gid=portage, x-mount.mkdir=7750 0

SSD Optimization:

Some of websites mention the use of discard mount option in fstab, but as SSD from Gentoo wiki and Solid State Drive from Archwiki stated, using the discard mount option is called continuous TRIM and it's not recommended. Instead, it suggests to run fstrim periodically. So, that's what I did using cron.# crontab -e =================================== # Global variables SHELL=/bin/bash PATH=/sbin:/bin:/usr/sbin:/usr/bin MAILTO=root HOME=/ # For details see man 5 crontab # Example of job definition: # .---------------- minute (0 - 59) # |  .------------- hour (0 - 23) # |  |  .---------- day of month (1 - 31) # |  |  |  .------- month (1 - 12) OR jan,feb,mar,apr ... # |  |  |  |  .---- day of week (0 - 6) (Sunday=0 or 7) OR sun,mon,tue,wed,thu,fri,sat # |  |  |  |  | # * * * * * user-name command to be executed 15 04 * * 6 /sbin/fstrim /

XDG cache on tmpfs:

Many X Window System programs, such as Chromium, Firefox, etc..., make frequent disk I/O every few seconds to cache. To reduce strains to SSD, the default cache location can be changed to tmpfs. The default cache location is ~/.cache and this is HDD for my case but I sent it to tmpfs anyway.# nvim /etc/profile.d/xdg_cache_home.sh ============================================ if [ $USER ]; then export XDG_CACHE_HOME="/tmp/${USER}/.cache" fi

make.conf:

/etc/portage/make.conf is used to customize the Portage environment for the entire system (not per package or user). The settings defined in this file will be applied to all packages that are being installed (or emerged). So far, these are my custom settings: # cat /etc/portage/make.conf ================== CFLAGS="-march=native -O2 -pipe" ... # The number of parallel make jobs that can be used MAKEOPTS="-j7" # USE flags USE="-emacs -kde -gnome -bluetooth alsa" # Language codes for US English and Japanese L10N="en en-US ja"

X11:

If startx can't be found, it most likely X11 didn't get installed. # emerge --ask x11-base/xorg-server

System Logger:

During the installation, I chose to install system logger (app-admin/sysklogd) and this may display the following messages in console:

sysklogd: /dev/xconsole: No such file or directory

When the message starts to appear, updating its configuration file should solve it. # nvim /etc/syslog.conf ============ ... #daemon.*;mail.*;\ # news.err;\ # *.=debug;*.=info;\ # *.=notice;*.=warn |/dev/xconsole

ALSA Issues:

I have another post with more details about issues with ALSA sound, but to sum it up,I need to enable SND_HDA_CODEC_CONEXANT in the kernel options. The HD-audio component apparently consists of two parts, the driver and codec, and correct options need to be enabled.

eix:

eix is a set of utilities for searching and diffing local ebuild repositories using a binary cache. This is used to audit installed packages for maintenance. Use eix Gentoo wiki for how to set it up. # emerge --ask app-portage/eix
