Use ubuntu/Intellij like macOS X

How to mimic full macOS Intellij behavior in Ubuntu

• Enviroment
  • Ubuntu 20.04
  • Intellij IDEA 2020

Ubuntu gnome shell shortcuts

• remove all <Super> related hotkeys in Settings -> Keyboard Shortcuts. They conflicts to lots of Intellij hotkey

  • ensure Switch Application set to Super+Tab (may overwrite after gnome update)
  • ensure Show all applications to disabled (may overwrite after gnome update)
  • Navigation -> Hide all normal windows conflict to Cmd+d, it's better to disable it

• remove Overview Shortcut (show all window by just press Super)

  • gsettings set org.gnome.mutter overlay-key ""

• diagnosis hidden shortcuts in gnome shell:

  • referece: https://askubuntu.com/questions/1069580/ubuntu-18-04-supero-cant-trigger-shortcut-event
  • <Super>, <Ctrl>, <Primary>... etc may conflict to Intellij, just check one by one

   ## such as `<Super>o` 
   (for schema in $(gsettings list-schemas); do gsettings list-recursively $schema; done) | grep '<Super>o'

• remove Intellij confliction

## `<Super>o` conflict to open class
gsettings set org.gnome.settings-daemon.plugins.media-keys rotate-video-lock-static '[]'

## `<Primary>Space` conflict to autocomplete Ctrl-Space
gsettings set org.gnome.desktop.wm.keybindings panel-main-menu '[]'

## `<Super>p` conflict to Intellij's parameter info
gsettings set org.gnome.mutter.keybindings switch-monitor '[]'

## `<Super>n` conflict to Intellij's new...
gsettings set org.gnome.shell.keybindings focus-active-notification '[]'

• IME related tweaks (apply if you use IBus multi-language switch, such as Chinese)

## <Alt>space conflict to IME
gsettings set org.gnome.desktop.wm.keybindings activate-window-menu '[]'

Gnome Tweak Tool

sudo apt install gnome-tweak-tool

Intellij

• Settings -> Keymap -> Get more keymap -> install macOS keymap

• choose macOS keymap upder Settings -> Keymap

  • the keymap utilizes Meta, which rely on above xkbsetmap

• enlarge fs notify limit

  • detail see https://confluence.jetbrains.com/display/IDEADEV/Inotify+Watches+Limit

• xkbsetmap to mapping altwin to meta_win

  1. add xkbsetmap command at the end of kinto_tweak.py

        import os
        os.system("/usr/bin/setxkbmap -option altwin:meta_win")
     

     adding setxkbmap command while login not work because kinto always reset xkb

  2. using gnome-tweaks (not work anymore, just for reference)

     • open gnome-tweaks app -> Keyboard & Mouse
     • Overview Shortcut -> Addtional Layout Options
     • Alt/Win key behavior -> Meta is mapping to Win
       • this allow Intellij use Meta modifier in X Window
       • reference: https://askubuntu.com/questions/604496/using-mac-os-shortcuts-in-intellij-idea-with-ubuntu
       • restart intellij after apply

• make cmd+click works

  • open gnome-tweaks app -> Windows -> Window Action Key -> Disabled
  • but multiple choose single file not work yet, use Ctrl+Button 1 Click to workaround

Kinto

• https://github.com/rbreaves/kinto

• flow install instruction

• copy kinto_tweak.py to ~/.config/kinto/kinto.py

• restart when you change kinto.py:

sudo systemctl restart xkeysnail

• kinto_tweak.py just copy from original kinto.py, with some modification, see jetbrains variable
  • cmd-tab and ctl-tab sections are also tweaked, revert it if it does not apply to your case
