Yubo Dotfiles

These are all my dotfiles and now a lot more. Want to be able to pacstrap, clone the repo and make install all the things.

Order of things

• UEFI + set up partitions (fdisk or through native OS)
  • Note: May need to write GPT + create EFI partition
  • mkfs.ext4 /dev/sdaX
• Mount /mnt
• pacstrap -i /mnt base base-devel linux linux-firmware
• Mount /mnt/boot
• genfstab -U /mnt > /mnt/etc/fstab
• bootctl --esp-path=/mnt/boot install, then create entries + loader.conf
  • Sample entry

title Arch Linux Macbook
linux /vmlinuz-linux-macbook
initrd /initramfs-linux-macbook-fallback.img
options rw root=UUID=<...>

• /mnt/etc/locale.conf edits, echo KEYMAP=dvorak > /mnt/etc/vconsole.conf

• arch-chroot /mnt

• locale-gen

  • NB: do not forget this step, need locales to xdg-open correctly

• pacman -S git dhcpcd zsh gvim

  • gvim since I'll want +X11 support later anyway, though it's much larger

• git clone https://[email protected]/yubo56/dotFiles.git ~/dotfiles

  • can comment out install_wpa_supplicant if have lan connection
  • use personal access token from Gmail Tasks
  • may need to grab keybase-encrypted id_rsa

• make root

• Reboot, login to new user

• sudo dhcpcd or connect to wifi

• clean /etc/pacman.d/mirrorlist

• make linux

Setup on Mac (MacOS)

• On mac, set hostname: sudo scutil --set HostName <...>

• karabiner.json belongs in ~/.config/karabiner/karabiner.json

  • Simple mods (should be in k.json): ust remap capslock -> control in system prefs, swap left_option and left_command for every individual keyboard, swap Fn and left_ctrl for MacOS (should be in Karabiner.json)
  • Rules are applied in reverse precedence
  • Convention: map from only left modifiers, map only to right modifiers

• "System Preferences > Keyboard > Shortcuts > App Shortcuts", add bizzare modifier for 'Minimize/Minimise' to disable accidental minimize

  • Can also use Automator to start screen saver, add shortcut under Services
    • "Quick Action" --> "Start Screen Saver" (search) --> "Workflow receives: no input" -->
    • Settings: Keyboard --> Shortcuts --> Services -->

• Notes from latest setup (Aug 31, 2022):

  • install dev tools, keybase, karabiner
  • git clone dotfiles, get id_rsa to bootstrap all private repos
    • git submodule init, make submodule_to_htps, git submodule update private, make decode_keys, make submodule_to_git, then git submodule update --recursive
  • install brew
  • brew install stow, tmux, coreutils, moreutils
    • linearmouse for disable mouse accel
  • may need to cp python3 and pip3 in brew bin to un-namespaced
  • brew install vim
  • if Intel silicon, will need to change $PATH

Setup on Mac (linux)

• yaourt -S hid-apple-patched-git-dkms, use config file from .setup/config_manual
• To get IGD:
  • apple_set_os, add bootloader entry
  • kernel param mem_encrypt=off
  • may need to compile with kernel params

CONFIG_EXTRA_FIRMWARE="radeon/verde_ce.bin radeon/verde_mc.bin radeon/verde_me.bin radeon/verde_pfp.bin radeon/verde_rlc.bin radeon/verde_smc.bin radeon/TAHITI_uvd.bin"
CONFIG_EXTRA_FIRMWARE_DIR="/lib/firmware"

misc notes

• Screensaver on suspend uses 00xscreensaver on home, xscreensaver.service on Mac
• sudo sysctl kernel/unprivileged_userns_clone=1 for Brave namespaces
• Bluetooth headset: bluez bluez-utils pulseaudio-bluetooth pulseaudio-alsa
  • Pulseaudio asound.conf, /etc/pulse/defaultpa: load-module module-switch-on-connect
  • bluetoothctl: power on; agent on; scan on; pair <...>; trust <...>; connect <...>
• transparency: sudo pacman -S xcompmgr transset-df
  • devilspie used to be used to match windows on open, broken now
• droidcam /etc/modprobe.d/droidcam.conf resolution, /opt/urserver/urserver to start Unified Remote
  • yaourt -S droidcam adb unified-remote-server
• For audio, need ~/.asoundrc, check which sound card via alsamixer, then

pcm.!default {
    type hw
    card 1
}
ctl.!default {
    type hw
    card 1
}

- When bluetooth is connected, need to use pulseaudio, default is in
  `/etc/asound.conf`, e.g.

pcm.!default {
  type pulse
  fallback "sysdefault"
  hint {
    show on
    description "Default ALSA Output (currently PulseAudio Sound Server)"
  }
}

ctl.!default {
  type pulse
  fallback "sysdefault"
}

• if dmenu is randomly crashing, strace dmenu_run, but probably need to git clone and re-install (4.9-1 seems to have this problem)
• Anaconda install: conda install -c lightsource2-tag zsh, conda install -c conda-forge gcc_linux-64
• To get headphones + mic working:
  • can I figure out autobluetooth?
  • pacmd set-card-profile <card> headset_head_unit or a2dp_sink (latter is the high-quality audio, no source)
  • pactl set-default-source <card>
