Ubuntu minimal installation + DWM

Download the Network Installer image of your architecture below:

https://ubuntu.com/download/alternative-downloads#network-installer

In my computer, I have to unplug the graphic card in order for the installation pendrive to boot the installer. Otherwise it freezes.

Installation

  1. Unplug the graphic card from the motherboard
  2. Insert the installation media and follow installation

Post installation

  • Reboot system
  • Sign in as user
  • Assign a password to root user: $ sudo passwd root
  • Edit /etc/NetworkManager/NetworkManager.conf and add this line under [main]:
auth-polkit=false
  • Edit /etc/systemd/journald.conf and uncomment this line:
SystemMaxFiles=1

If you don't edit the two files as explained above, you'll get huge logs files:

  • /var/log/syslog
  • /var/log/journal/

Install basic programs and libraries

sudo apt update
sudo apt install vim xserver-xorg xinit lynx zathura ranger feh -y
sudo apt install network-manager -y
sudo apt install git make libx11-dev libxft-dev libxinerama-dev -y
sudo apt install apt-transport-https curl -y

DWM installation

After performing a Ubuntu minimal installation, follow DWM installation instructions here: https://linuxdocs.netlify.app/i3wm#dwm

Once you have installed DWM and the other suckless programs, edit your .profile file and append these lines at the end:

feh --bg-scale .wallpaper/ubuntu.jpg
.config/dwm/dwm-bar/./dwm_bar.sh &

Now create/edit your .xinitrc and add:

dwm

You can automate the installation by running these commands:

wget https://raw.githubusercontent.com/cheomanigua/config/master/suckless/ubuntu/ubuntu_autoinstall_dwm
sudo chmod +x ubuntu_autoinstall_dwm
sudo ./ubuntu_autoinstall_dwm

Install CUDA driver

Note: There must be NO nvidia driver installed, nor nvidia card inserted in the PC prior to following the installation process below

sudo apt install gcc
wget https://developer.download.nvidia.com/compute/cuda/repos/ubuntu2004/x86_64/cuda-ubuntu2004.pin
sudo mv cuda-ubuntu2004.pin /etc/apt/preferences.d/cuda-repository-pin-600
wget https://developer.download.nvidia.com/compute/cuda/11.1.0/local_installers/cuda-repo-ubuntu2004-11-1-local_11.1.0-455.23.05-1_amd64.deb
sudo dpkg -i cuda-repo-ubuntu2004-11-1-local_11.1.0-455.23.05-1_amd64.deb
sudo apt-key add /var/cuda-repo-ubuntu2004-11-1-local/7fa2af80.pub
sudo apt-get update
sudo apt-get -y install cuda
nvidia-smi

The original instructions are in this page.

You can now poweroff the computer, insert the graphic card, plug the hdmi cable in the graphic card, and start the computer.

Install DaVinci Resolve Studio

  • Download the Linux version of Davinci Resolve from https://www.blackmagicdesign.com/products/davinciresolve/
  • Go to the directory where you downloaded Davinci Resolve
  • Unzip: $ unzip DaVinci_Resolve_16.0b7_Linux.zip
  • Install: $ sudo ./DaVinci_Resolve_16.0b7_Linux.run -i
  • Launch: Activities -> Search box -> Type "Davinci"

Note: The first time that Davinci Resolve 16 is launched, the welcome screen will get stuck (it will remain white). Launch "System Monitor" and end the process "DaVinci_Resolve_Welcome". Davinci Resolve 16 will get "unstuck" and open up normally.

Debian minimal installation + Openbox

Download the Small CDs or USB sticks image of your architecture below:

https://www.debian.org/distrib/netinst

In my computer, I have to unplug the graphic card in order for the installation pendrive to boot the installer. Otherwise it freezes.

Installation

  1. Unplug the graphic card from the motherboard
  2. Insert the installation media and follow installation

Post installation

  • Reboot system
  • Sign in as user
  • Assign a password to root user: $ sudo passwd root
  • Edit /etc/NetworkManager/NetworkManager.conf and add this line under [main]:
auth-polkit=false
  • Edit /etc/systemd/journald.conf and uncomment this line:
SystemMaxFiles=1

If you don't edit the two files as explained above, you'll get huge logs files:

  • /var/log/syslog
  • /var/log/journal/

Install Openbox

Note: You can skip the manual instructions below by running the script at GitHub. Follow the instructions on the README file.

# apt install openbox lxdm obconf obmenu qterminal featherpad pcmanfm tint2 gsimplecal feh numlockx lxappearance 
# apt install firefox vlc
# wget -qO- https://git.io/papirus-icon-theme-install | sh
# apt install build-essential

build-essential is only necessary if you are a developer as npm will need it in order to install packages.

Configure Openbox

Wallpaper and Tint2 panel

  • Create file ~/.config/openbox/autostart.sh and add:
feh --bg-scale ~/.wallpaper/image1.png &
(sleep 2s && tint2) &

Calendar

We installed gsimplecal in the installations steps above. To make it show when clicking on the clock of the panel, edit ~/.config/tint2/tint2rc and change this line to this:

clock_lclick_command = gsimplecal

Icon Themes

We can select an icon theme launching lxappearence. We downloaded and installed the papirus icon theme with the command wget on the step above Installing Openbox.

Mouse cursor Themes

  1. Install one of the cursor theme packages:

sudo install dmz-cursor-theme

  1. Launch LXappearance and select 'Mouse Cursor' tab and 'DMZ (White')' theme.

  2. Edit ~/.icons/default/index.theme:

[Icon Theme]
Name=Default
Comment=Default Cursor Theme
Inherits=DMZ-White
  1. Create a symlink:

ln -s /usr/share/icons/DMZ-White/cursors ~/.icons/default/cursors

  1. Check that symlink was created successfully:
$ ls -l ~/.icons/default/cursors
/home/cheo/.icons/default/cursors -> /usr/share/icons/DMZ-White/cursors
  1. Reboot

Extra: If for whatever reason you want to delete the symlink in the future:

rm ~/.icons/default/cursors

Disk Management

Automount an external disk

  1. Check where the external disk is:
$ lsblk
NAME   MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
sda      8:0    0 111.8G  0 disk 
├─sda1   8:1    0   499M  0 part 
└─sda2   8:2    0 111.3G  0 part /
sdb      8:16   0 223.6G  0 disk 
├─sdb1   8:17   0    16M  0 part 
└─sdb2   8:18   0 223.6G  0 part
  1. In this example, the disk we want to automount is the partition/sdb/sdb2. We need to find out the UUID and TYPE of /dev/sdb2:
$ sudo blkid /dev/sdb2
/dev/sdb2: LABEL="Datos" UUID="368A7A9A8A7A5679" TYPE="ntfs" PARTLABEL="Basic data partition" PARTUUID="670e8067-f3d4-44db-a493-d69e4c9e2e9e"
  1. We now create a directory to accomodate /dev/sdb2 when it automounts:
$ sudo mkdir /media/datos
  1. We can now edit /etc/fstab and add:
UUID=368A7A9A8A7A5679 /media/datos ntfs rw,exec 0 0

rw,exec gives write, read and execute permission to all users.

Remove Snap from the system

snap list
sudo systemctl stop snapd
sudo systemctl disable snapd
sudo apt purge snapd
rm -rf ~/snap
sudo rm -rf /snap /var/snap /var/lib/snapd /var/cache/snapd /usr/lib/snapd
snap list

Leafpad from source

The reason to compile from source instead of using the package manager is because Leafpad has the tab width hard coded and cannot be changed from the application menus. I want to use a tab width of 2 instead of the default tab width of 8.

Download and unpack the tarball file

$ wget http://savannah.nongnu.org/download/leafpad/leafpad-0.8.17.tar.gz
$ tar xzvf leafpad-x.x.x.tar.gz       # unpack the sources
$ cd leafpad-x.x.x                    # change to the toplevel directory

Change the tab_width

Edit src/indent.c and find the following lines and change the values as below:

static gint default_tab_width = 2;
static gint current_tab_width = 2;
if (default_tab_width == 2)
  current_tab_width = 1;
else
  current_tab_width = 2;

Compile

Note that you will first need to installthe GTK+-2.x.x libraries if you don't have them installed already:

$ sudo apt install libgtk2.0-dev

Then you can compile:

$ ./configure                         # run the `configure' script
$ make                                # build Leafpad
$ sudo make install-strip
