Getting Mac-Like Workspaces on Ubuntu 17.04
It can be frustrating using many windows on a small screen, but multiple workspaces can give you the space you need. Install Fusuma to help you switch between workspaces very fast.
If you do software development on a laptop like me, you know the struggle. You've got the editor, the program, the project specs, a few file browsers, a dozen docs, a terminal or two, ssh, and some debug tools, but all you've got for displays is one tiny peephole of a screen. Buried alive in windows your work flow is more of a work farce. You can't get any thing done like this.
What is one to do? You could use a fancy tiling window manager (you know the ones with all the key combos), But your touch typing isn't all that great; you're not ready to ditch the mouse. What about workspaces? Ah, now that has promise. It's like having several monitors to spread things out. You can have all the room you need. However, you will need some way of switching between workspaces. You could use the keyboard shortcuts, but Ctr+Alt+Left and Ctr+Alt+Right are so far from the home row and they take both hands to type. Besides didn't we just say we're not ditching the mouse? You could put a button on the task bar. That might be okay, but it takes up screen space and you have to go and click it every time.
We can do better. If you have a multi-touch track-pad you can control your window manager with swiping gestures. MacOS already has this built in. With three fingers swiping left or right switches workspaces and a swipe up spreads the widows. In order to get the same functionality in Linux we will need to install Fusuma. Fusuma runs in the background and translates multi-touch gestures to keyboard shortcuts.
Setting Up Workspaces
First you need to setup your workspaces. By default Ubuntu 17.04 uses 4 workspaces in a square. This will not work for us since we plan to only switch left and right not up or down. I recommend using four workspaces in a single row. To set this up just run the commands:
gsettings set org.compiz.core:/org/compiz/profiles/unity/plugins/core/ hsize 4 gsettings set org.compiz.core:/org/compiz/profiles/unity/plugins/core/ vsize 1
If you want more or less workspaces just run:
gsettings set org.compiz.core:/org/compiz/profiles/unity/plugins/core/ hsize <put your number here>
libinput-tools to read mouse events and
xdotool to generate
keyboard events. Fusuma is also a ruby program and is managed with
you'll need ruby as well. These can all be installed with apt:
sudo apt install libinput-tools xdotool ruby
Fusuma will also need permission to read from
/dev/input. You could run it
with sudo but that would require a password every time. A better solution is to
add yourself to the input user group.
Once you have the dependences just install Fusuma with:
sudo gem install fusuma
Later on you can update Fusuma with:
sudo gem update fusuma
Fusuma's default config location is
~/.config/fusuma/config.yml. You will need
to create this directory and file yourself. The quickest way to do this is:
mkdir ~/.config/fusuma cat > ~/.config/fusuma/config.yml <paste config text here> ^C
For your config I recommend:
swipe: 3: left: shortcut: "ctrl+alt+Right" right: shortcut: "ctrl+alt+Left" up: shortcut: "super+w" down: shortcut: "super+w" pinch: in: shortcut: "ctrl+plus" out: shortcut: "ctrl+minus" threshold: swipe: 0.5 pinch: 0.25 interval: swipe: 0.2 pinch: 1
This will give you similar functionality to macOS. If you ever edit this config you will need to restart Fusuma.
From Command Line
You can run Fusuma with the command
fusuma. However this will kill Fusuma if
you close the terminal. A better way is to do:
nohup fusuma &
This will run Fusuma as if it were a daemon and will let you close the terminal.
In order to make Fusuma run automatically on login just add it to your startup
applications with the name "Fusuma" and the command
fusuma. You don't need
