Global notes about the system configuration

Notes, tips

• <Enter>, ~, . to kill ssh session that hunged up. (dot kills) <Enter>, ~, ? should print help
• rendering with GPU offload support (multiMC "wrapper command" without final program name):

  env __NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia someProgramName
  

Things I changed:

  • MenuLibre (for editing menu icons)
• PS1 customization in .prompt.sh.

• 'ffmpeg-progressbar-cli' npm global package -- a wrapper for ffmpeg that shows bar and ETA: (https://github.com/sidneys/ffmpeg-progressbar-cli)

• Short bash prompt displays in multiline with more info
• Wireguard and Openvpn configs to use on prask

  • enabled auto-switch module in /usr/share/pipewire/pipewire-pulse.conf
• enabled system prober in GRUB
• installed preload daemon
• installed reptyr - to reattach process to different parent (so that normal terminal task can be reattached to tmux)
• installed gtk-3-examples - https://askubuntu.com/questions/685507/where-are-my-gtk-3-examples
• installed encfs
• installed gdbgui
• installed gpm - github package manager
• installed glow for displaying markdown docsi nterminal
• installed btop from binary release
• installed pipx and python3.10-venv
• installed sqlitebrowser and sqlite3
• added thumbnailers for .ora .kra .psd .xcf, (the xcf one is missing xcf2png to work)
• Installed ratarmount into /usr/local/bin/ratarmount
• installed binwalk
• installed touchegg deb for 3-finger gestures on X. Remove this when migrating to wayland
  • also with it installed x11 gestures extension
• installed sourcegraph - intelligent source code index, soon with AI and sourcegraph cli as global npm module
• installed ffmpegthumbnailer and gstreamer1.0-libav, disabled totem thumbnailer inside /usr/share/thumbnailers/totem.thumbnailer (it was crashing)

Added linked /usr/local/bin/pixelart-thumbnailer script, which creates thumbnails that generates pixel-art thumbnail with filter=point if it's under certain size (thumbnail size %s). This makes displaying small pixelart textures crisp.
• ~/.selected_editor has vim.gtk3 now to support clipboard in different programs like anacron -e
• installed (a long time ago) webi
  • installed pathman for managing path entries (automatically)
  • installed bat
  • installed fd, a find on steroids
  • installed lsd, an ls and tree on steroids (although tree is not that performant)
  • installed xsv for quick csv editing in CLI
  • ! removed webi as it made locating info about packages/programs impossible and confusing. Without remembering there was no way of knowing if a program was installed with webi
• added .alsoftrc to configure OpenAL to use pulseaudio driver by default instead of JACK. This cames from this github issue
• moved from tldr++ to node client tldr
  • no special reason, I just did it during upgrade to zsh.
  • the difference is that the first has interactive selection, but sometimes locked terminal input for some reason. The first one was also faster at the time.
• installed diff-so-fancy and configured as a default git diff pager
• installed lazygit, configured to use difft by default as a diff tool
• git now uses difft by default
• installed miniconda for various AI work
  • added ~/.condarc to disable activation of base conda environment
  • to configure: use conda [de]activate
• removed Ora snap, it's available as a webapp, and it's freemium so I don't use it often
• installed blender and godot flatpaks
• removed kdenlive, I may install it from flathub one day but I don't need it for now
• removed all snaps and snapd this way:
  • blockbench
  • ora
  • blender
  • and others...
• added auto commands for opening gpg encrypted files in nvim
• removed postfix, gnome app for email (E-something)
• installed nala
  • configured /etc/nala/nala.con to apt upgrade instead of apt full-upgrade
• installed packages:
  • libimage-exiftool-perl for exiftools
  • ubuntu-restricted-extras for codecs and M$ true type fonts
  • somehow support for webp in gnome
  • libavif-gdk-pixbuf in the hopes of supporting avif in image viewers and thumbnailers
• set export MUTTER_DEBUG_KMS_THREAD_TYPE=user in the /etc/environment to solve the mutter issue in ubuntu 24 where I can't login to wayland unless I switch to TTY and back
• installed fzf by cloning into ~/.fzf and doing install
• added .config/xkb custom CAPS handling, and it should work out of the box on wayland.
  • this is a PITA to configure on Xorg so I edited /usr/share/X11/xkb/symbols/pc and changed the CAPS key
• installed mold for faster builds (used by rustc). Requires manual execution with -fuse-ld=mold flag

To backup:

• gnome shortcuts
• app list
• /etc/skel ?
• groups
• cron and anacron jobs
• ssh keys and configurations
• compose comnfigurations for X
• saved network settings
• many different config files annotated with 'tooster' - best bet is to look for strings across system
• XCompose

Dotfiles:

I manage dotfiles by running dotfiles command which is aliased to some smart git working on bare repo in ~/.git
