Fancontrol (Linux)

Warning: Don't use this. The fan controller IDs may change on every reboot which breaks the config.

Configure Sensors

1. Install lm-sensors.
2. Run sensors-detect.
   1. Answer with the default answers.
   2. At the end, allow it to add the modules to /etc/modules.
3. Reload the kmod service to reload the modules.
4. Watch the kernel log to check for sensor errors. If so, try to remove the modules added to /etc/modules with modprobe -r <module> to see if the error goes away. If so, remove it from the modules file.

Configure Fancontrol

1. Install fancontrol.
2. (Optional) Install gnuplot if you want pwmconfig to generate graphical plots.
3. Run pwmconfig.
   1. Use manual mode for when asked.
   2. Generate detailed correlations when asked.
   3. Set up the config file when asked (/etc/fancontrol).
   4. Decide which sensor each controller should depend on.
   5. Configure all fan controllers.
   6. Save and quit.
4. Tweak the config:
   1. Open /etc/fancontrol.
   2. Round up all numbers, just to make it a little cleaner.
   3. Set interval to around 2 seconds.
5. Restart the fancontrol service.

Firefox

Config

Git

Config

• Location: ~/.gitconfig
• Example.

Nvidia Settings (Linux)

• To save, use the "save current configuration" button and save it to /etc/X11/xorg.conf.

Piper (Linux)

GUI for configuring gaming mice.

Setup

1. Install the piper PPA.
2. Install piper.
3. Configure the mouse using the GUI application.

PuTTY (Windows)

• In Terminal > Features, activate Disable application keypad mode.
• In Window > Appearance, change font to Consolas, regular, size 10.
• In Window > Colours, set all ANSI non-bold colors to the same as the bold ones.

Screen

Usage

Serial

• Open serial session: screen /dev/ttyUSB0 38400,-crtscts (38400 baud, no flow control)
• End session: Ctrl+A, \
• Note: For some devices, you may need to use Ctrl+H instead of backspace.

SMB

Troubleshooting

• If using DNS instead of NetBIOS and the client freezes while connecting to a share, try enabling the "Routing and Remote Access" service.

Speedfan (Windows)

• Warning: The controller symlinks likes to change on boot, meaning the config may break every boot. This makes it literally useless.
• Manually add startup shortcut.
• Disable Do SMART Summary Error Log scan on startup since it may cause the PC to freeze.
  • Alternatively, use the CLI argument /NOSMARTSCAN.
• Set the PWM mode for fans which will be controlled by Speedfan to manual.

SSH

Usage

• New key (RSA): ssh-keygen -t rsa -b 4096

Config

• Location: ~/.ssh/config
• Example.

Steam (Linux)

Installation (Kubuntu)

Using Kubuntu Repos or Downloading the Officlal DEB File

Note: Since Steam requires 32-bit (i386) variants of certain NVIDIA packages, and NVIDIA not releasing i386 variants any more as of driver version 465 ish, any normal installation is impossible. The Ubuntu dudes have a PPA containing unofficial i386 variants for the relevant NVIDIA driver packages, but it conflicts with official CUDA packages, which is not nice if you need CUDA.

Using Flatpak

• See Steam (Flatpak).
• This doesn't require the dumb i386 NVIDIA driver packages.
• As long as ValveSoftware/steam-for-linux #7847 isn't fixed, make sure to not enable "remember my password". If you do and it crashes on the next start, run flatpak run com.valvesoftware.Steam --reset (if using Flatpak) to reset the user config and then lanuch it normally afterward.

Miscellanea

• Windows home dir (typical save location): ~/.local/share/Steam/steamapps/compatdata/<some_id>/pfx/drive_c/users/steamuser/

ZSH (personal) (Linux)

This is my personal ZSH setup using Oh-My-ZSH with the Powerlevel9k theme and Hack font.

1. Install ZSH:
   1. apt install zsh
2. Install Oh-My-ZSH:
   1. See ohmyz.sh.
   2. When it asks, set it as your default shell. This won't take effect until the next login.
3. Setup Powerlevel10k theme:
   1. Download and install the suggested fonts (manually is simplest): Fonts (powerlevel10k)
   2. Open a new terminal window and set change the profile to use the new font.
   3. Clone the theme: git clone --depth=1 https://github.com/romkatv/powerlevel10k.git ~/.oh-my-zsh/themes/powerlevel10k
   4. In ~/.zshrc, set ZSH_THEME="powerlevel10k/powerlevel10k".
   5. Open a new ZSH session (or restart your terminal).
   6. Configure the theme (if it didn't automatically start): p10k configure
4. Make zprofile include profile (to avoid breaking certain things):
   1. In ~/.zprofile, add: emulate sh -c "source /etc/profile"
5. Setup syntax highlighting plugin:
   1. Clone it: git clone https://github.com/zsh-users/zsh-syntax-highlighting.git ~/.oh-my-zsh/custom/plugins/zsh-syntax-highlighting
   2. Add it to plugins in .zshrc (e.g. plugins=(git zsh-syntax-highlighting)).
6. Configure ~/.zshrc:
   1. Example zshrc.
