Linux-setup

My setup scripts and configurations for Ubuntu 20.04 LTS. Largely a repo for keeping track of all the little tweaks and common fixes that I seem to end up dealing with when working with Linux systems.

• always sudo apt update first
• see refresh_ubuntu_install_scripts.sh for install scripts for Ubuntu 20.04 refresh
• see portable-linux.md for how to install Ubuntu on a portable SSD that can work on almost any computer of the same architecture.
• see bash_aliases for some of my common bash aliases (need to update)

Different Backgrounds for Different Monitors

• https://gitlab.com/gabmus/HydraPaper#flatpak-universal-package

• Assume flatpak is already installed (https://flatpak.org/setup/Ubuntu)

  sudo apt install flatpak
  flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo
  

• restart the system

  flatpak install flathub org.gabmus.hydrapaper
  flatpak run org.gabmus.hydrapaper
  

A good start to drivers

• Automatically install drivers, and this can streamline the installation of Nvidia drivers https://askubuntu.com/questions/543325/how-to-download-all-required-ubuntu-drivers

  sudo ubuntu-drivers autoinstall
  sudo reboot
  

Oh my zsh

More featured terminal, also applicable for Mac OSX

• Main oh my zsh program sh -c "$(curl -fsSL https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"
• Powerlevel10k https://github.com/romkatv/powerlevel10k#oh-my-zsh
• Fuzzy logic finder, fzf: https://github.com/junegunn/fzf, note: brew for MacOS, or sudo apt for Ubuntu. The second line below installs useful key bindings and fuzzy completion

brew install fzf
$(brew --prefix)/opt/fzf/install

• zsh-suggestions: https://github.com/zsh-users/zsh-autosuggestions/blob/master/INSTALL.md
