In no particular order, below is a list of commands/settings I frequently use on my machines. I’m collecting them here to avoid the hours of googling typically involved when I install a distro on a fresh machine.

  • Make current monitor configuration persistent (Gnome display manager; gdm3)

    • # Copy current config to gdm3 default settings
sudo cp ~/.config/monitors.xml /var/lib/gdm3/.config

  • Enable syntax highlighting in less

    • # Syntax highlighting with less
# Depends on: source-highlight
export LESSOPEN="| /usr/share/source-highlight/src-hilite-lesspipe.sh %s"
# Set default options: Enable raw control characters and enable line numbers
export LESS='-RN'

  • Restart pipewire (audio service).

    • Sometimes after waking from sleep, I found my audio services we’re not working properly. A quick workaround is to restart the service.

    • systemctl --user restart wireplumber pipewire pipewire-pulse

  • Disable split-lock detect: Causes CPU throttling for some games running under proton.

    • # Add kernel boot parameter (For pop_os machines)
sudo kernelstub -a "split_lock_detect=off"
# Verify boot option is added
sudo kernelstub -p

    • # Disable split-lock at runtime (Kernel >= 6.2)
sudo sysctl kernel.split_lock_mitigate=0
