Disclaimer :

This Gist mostly consist of this previous gist (created on 08/02/2018), but with a more recent flavor (more accurate and up to date).

Part 1 : Starting config

Vulkan

sudo dpkg --add-architecture i386 \
&& sudo apt update \
&& sudo apt upgrade \
&& sudo apt install libgl1-mesa-dri:i386 mesa-vulkan-drivers mesa-vulkan-drivers:i386

Change cursor (link)

Download cursor theme from Gnome Look or other sources (Breeze).
Untar it in /usr/share/icons.
In Gnome Tweak Tool, change the cursor theme.

Change GTK theme

Download GTK theme and install required dependencies (Vimix).
Untar the theme in /usr/share/themes.
Change theme with Gnome Tweak Tool.

Custom prompt for the Termial

Install Oh-my-Posh :

wget https://github.com/JanDeDobbeleer/oh-my-posh/releases/latest/download/posh-linux-amd64 -O /usr/local/bin/oh-my-posh
chmod +x /usr/local/bin/oh-my-posh

Intall a theme, for exemple (add this line in your .bashrc) :

eval "$(posh-linux-amd64 --init --shell bash --config ~/.poshthemes/agnoster.omp.json)"

Install a Monospace Nerd Font (should be in the ~/.local/share/fonts/).
Rebuild cache if you don't see it : fc-cache -fv

Part 2 : Package list

Gnome applet :

# Base packages
inxi (system info)
gnome-tweaks
vlc
unar (support RAR archive files)
checkinstall
etcher (Live CD)
JDownloader (use executable jar file on the editor's website)
antimicro (GUI for gamepad to keyboard, like JoyToKey) > (https://launchpad.net/~mdeguzis/+archive/ubuntu/libregeek/+files/antimicro_2.23~artful-1_amd64.deb)

# File managers
thunar

# Others
numix-icon-theme-circle
menulibre
realvnc-vnc-viewer
lftp (segmented download)
pv (progress)
dialog

# Emulators

Dolphin (Build from sources)

Part 3 : Apps config

Steam

Download and install steam deb package, witg dpkg -i (Steam will handle the 32bit architecture libs and prompt you if you have missing package).

Remote play config

Save yourself some time and disable a remote play setting, to fix a black screen issue in a game (Heave Ho).
Go to Settings | Remote Play | Advanced Client Options and disable (uncheck) hardware decoding.

Proton debug log

You can track down some info by launching the game with : PROTON_LOG=1 %command%
It will dump a useful debug log to $HOME/steam-$APPID.log
The APPID can be used to delete the Proton environment for a game, located in …steam/steamapps/compatdata (usefull if the game doesn't launch and you have tried everything).

Kill all steam process

When Steam is freezing like hell, you can kill all the process with pkill -9 steam.
This does not remove hanging executables (you still have to kill them with their PID).

Java

fix connection with PipeWire

To see if you run pipewire, use : pactl info.
There is a bug in Java that prevent it from using PipeWire.
Open (or create) the file /etc/openal/alsoft.conf.
Add/change this line : drivers = alsa.

Pipewire config

fix audio crackling source

Under heavy CPU load, audio crackling can occur if latency is too low and the system can't keep up.
Tldr, use this config in the file /etc/pipewire/pipewire.conf :

default.clock.rate          = 48000
default.clock.allowed-rates = [ 48000 ]
default.clock.quantum       = 800
default.clock.min-quantum   = 512
default.clock.max-quantum   = 1024

Lutris

fix "game need microsoft visual c++ runtime" error

GUI :

  • select game in Library
  • select Winetricks (arrow next to wine bottle)
  • choose the wineprefix and select "Install a Windows DLL or component"
  • find "vcrun2019" and go trough the installation process

CMD :

  • start GUI by hand : WINEPREFIX=/path/to/wineprefix winetricks
  • install one liner : WINEPREFIX=/path/to/wineprefix winetricks vcrun2019

LAZY :

  • download this all in one package
  • use "execute EXE inside wineprefix" or change the EXE location in lutris (run the bat file)

Part 4 : Misc

  • Good old ifconfig with the new IP command : alias ifconfig='ip -4 -o -c addr'.
  • Display current graphical server : echo $XDG_SESSION_TYPE.
  • Info about drivers : lspci -k | grep -EA3 'VGA|3D|Display' then modinfo <driver>.
  • List current broken packages : dpkg-query -f '${status} ${package}\n' -W | awk '$3 != "installed" {print $1 " " $2 " " $3 " " $4}'.
  • Change DNS server in /etc/resolv.conf file.
    • Permanently change DNS with : echo "nameserver 1.1.1.1" | sudo tee /etc/resolvconf/resolv.conf.d/base > /dev/null
  • Partition tools recap : fdisk (MBR - <2To) - gdisk (GPT - >2To) - parted (both) (source).
  • FFMPEG (guide)
    • interpolation : ffmpeg -i input.mkv -filter:v "minterpolate='mi_mode=mci:mc_mode=aobmc:vsbmc=1:fps=60'" output.mkv
    • x264 convertion : ffmpeg -i input.mkv -vcodec libx264 output.mvk
      • keep all streams : ffmpeg -i input.mkv -map 0 -c copy -c:v libx264 output.mvk
      • convert specific audio/video/subt stream : ffmpeg -i input.mkv -map 0:a -map 0:v -map 0:s -scodec mov_text output.mp4
    • upscale : ffmpeg -i input.mkv -vf scale=4096:2048 -c:v libx264 -crf 20 -preset slow output.mvk
    • merge audio into another file : ffmpeg -i <file1> -i <file2> -filter_complex "[1]adelay=1000|1000[s1];[s1]amix=1[mixout]" -map 0:v -vcodec copy -map [mixout] <fileOut>
      • one line loop : for i in {01..51}; do ffmpeg -i aFile$i* -i bFile$i* -filter_complex "[1]adelay=1000|1000[s1];[s1]amix=1[mixout]" -map 0:v -vcodec copy -map [mixout] outFile\_$i\_stuff.sample; done
      • [1]adelay=1000|1000[s1] : add a 1s delay to the 2nd input and output it to [s1]
      • [s1]amix=1[mixout] : use the new audio as [mixout] for the "map"
  • Num Lock at startup (set numlock-state with command line or dconf-editor) :
    • sudo -H -u gdm -s /bin/bash
    • dbus-launch gsettings set org.gnome.settings-daemon.peripherals.keyboard numlock-state 'on'

Part 5 : Ubuntu stuff
