Linux Setup

Intro

Private notes on setting up (or re-setting up) my Linux/Ubuntu/Debian system

Bash-completion

To autocomplete and make life easier

apt-get install bash-completion

Syncthing

To sync my document and files

apt-get install syncthing

Note: You can’t run syncthing as a daemon in a chroot. So like on a chromebook/crouton, you simply have to run it from the command line as syncthing and then control it throught the browser

Next we need to set up syncthing to autostart on the system and run in the background as a daemon. Daemons are managed by systemd. For a description see: http://n0where.net/understanding-systemd

We will run syncthing as a system-service so it runs even when you’re logged out. It can also be configured to run as a user-service that runs only when a user is logged in. This is described in the documentation. To create the system service, run:

systemctl enable [email protected]

geokon is my user name (replace is appropriate). Why does the system service require a username? Because “The Syncthing system service must be started for a user with a home directory because Syncthing needs to store configuration files under the user’s home directory.”

This creates some symlink from the systemd config files to some other stored file (for syncthing) that Debian has added to systemd for us. (these paths don’t make sense to me… but okay)

/etc/systemd/system/multi-user.target.wants/[email protected] -> /lib/systemd/system/[email protected]

Next we launch the service we’ve added

systemctl start [email protected]

To check it’s status there is the following systemd command

systemctl status [email protected]

But it’s a bit last-resort. It’s easier to check through the control panel
https://localhost:8384/

Fluxbox

apt-get install fluxbox
apt-get install xorg
apt-get install xserver-org

First install is about 20MB
Second is around 200MB to launch the X11 server and run fluxbox

startfluxbox

Other

fstab settings for autmounting device

/dev/disk/by-id/usb-SanDisk_Cruzer_Blade_4C531001550107103073-0:0-part1 /home/geokon/USB auto nosuid,nodev,nofail,x-gvfs-show,auto,exec,uid=geokon,gid=geokon,x-systemd.automount 0 0

this goes into /etc/fstab/ on a separate line on its own

In another version it looked like this for me

/dev/disk/by-id/usb-Samsung_Flash_Drive_0376618030015678-0:0-part1 /home/geokon/USB auto nosuid,nodev,nofail,x-gvfs-show,auto,exec,uid=geokon,gid=geokon,x-systemd.automount\0400\0400 0 0

giving permissions to sigrok

Need to be done by adding permissions files into /usr/lib/udev/rules.d/ https://sigrok.org/gitweb/?p=libsigrok.git;a=blob;f=README.devices https://raw.githubusercontent.com/sigrokproject/libsigrok/master/contrib/60-libsigrok.rules https://raw.githubusercontent.com/sigrokproject/libsigrok/master/contrib/61-libsigrok-uaccess.rules

Fonts

This is super confusing.. so this is just a list of notes

Ubuntu blocks bitmap fonts by default for some reason - so you need to delete some special file to reenable them. Details are here: https://wiki.ubuntu.com/Fonts#Enabling_Bitmapped_Fonts

If a bitmap font comes in a TrueType format, don’t use that! It will come out looking weird and will scale in strange ways

The tewi font has instructions on how to install things; https://github.com/lucy/tewi-font#installation You need to download the BDF file, then convert it to a PCF file, put them into a directory and use xset +fp /path/to/fontdir/ to then add that directory to the list of font directories. Then run fc-cache -fv to rescan all the fonts on the system. After that it should show up in the font menues

The .Xresources file will have two lines to setup Emacs and Xterm:

Emacs.font: Zpix
XTerm*faceName: Zpix

Emacs Daemon

The Daemon

In ~/.config/systemd/user/emacs.service you need to add a new service to run the Emacs daemon which should look like this

[Unit] Description=Emacs: the extensible, self-documenting text editor

[Service] Type=forking ExecStart=/usr/bin/emacs –daemon ExecStop=/usr/bin/emacsclient –eval “(progn (setq kill-emacs-hook ‘nil) (kill-emacs))” Environment=”LC_CTYPE=zh_CN.UTF-8” “XMODIFIERS=@im=fcitx” Restart=always

TimeoutStartSec=0

[Install] WantedBy=default.target

Then you launch it for the user

systemctl --user enable emacs.service
systemctl --user start emacs.service
#systemctl --user status emacs.service

The Client

In ~/.local/share/applications/ You need to remove the Emacs entry (usually emacs.desktop) and replace it with ~/.local/share/applications/emacsclient.desktop

Which will look like this

[Desktop Entry] Name=Emacs GenericName=Text Editor Comment=Edit text MimeType=text/english;text/plain;text/x-makefile;text/x-c++hdr;text/x-c++src;text/x-chdr;text/x-csrc;text/x-java;text/x-moc;text/x-pascal;text/x-tcl;text/x-tex;application/x-shellscript;text/x-c;text/x-c++; Exec=emacsclient -c Icon=emacs Type=Application Terminal=false Categories=Development;TextEditor;Utility; StartupWMClass=Emacs

Firefox

To use the downloaded verison of Firefox you need to add it to the menus and stuff so you can set it as default browser more easy.

In ~/.local/share/applications/ Add a firefox.desktop with:

[Desktop Entry] Type=Application Exec=/home/geokon/bin/firefox/firefox %u Icon=firefox Name=Firefox Categories=Internet; Comment=Custom definition for Firefox

fcitx

Once you install it and the frontend you need to run im-config and then select to configure fcitx (so click Yes when it suggests to click No and then you will see the option there). Then restart
