Installing Fedora 32 on a mid-2009 Macbook Pro - Part Two, i3wm

A series of posts documenting the installation of Fedora 32 onto a mid-2009 15" Macbook Pro. In three parts; Part One describes the initial installation of Fedora and necessary updates to detect the internal WiFi hardware, Part Two describes configuring the window manager i3wm, and Part Three details the installation of the applications that I use daily. As is usual with Linux installations, forewarned is forearmed. Prepare for the lack of internal WiFi capability in the base Fedora install. And, if you use the i3 Window Manager, there is additional work to allow the MacBook to return to active mode from standby when the lid is closed and subsequently re-opened.

Trying to use apps and tools that are less demanding of computational resources. Tools that suck less.[1]

Installing i3wm

I use i3wm[2], a fast and bare-bones "tiling" Window Manager.

1
$ sudo yum -y install i3 i3status dmenu feh rofi terminator i3lock st

The first time you run i3wm it will prompt to run its initial setup and to choose your mod key which i3wm then writes to ~/.config/i3/config.

Niceties in the Xfce4 installation image

i3wm requires additional utilities and applets to perform network management and configuration, bluetooth pairing, power management, and mouse/trackpad and brightness controls for screen and keyboard. Installing the Xfce[3] Fedora "Spins" Live Image — as I described in [part-one] — provides much of this functionality in a way that integrates well with i3wm.

Use the bluetooth applet to display the bluetooth icon in the i3 status bar.

Add the following to ~/.config/i3/config

1
exec --no-startup-id /usr/bin/blueberry-tray                # Bluetooth Manager

Use the Xfce the power manager applet to control screen and keyboard brightness. The power management icon is displayed in the the i3 status bar.

Add the following to .~/.config/i3/config

exec --no-startup-id /usr/bin/xfce4-power-manager           # Power Manager. For
                                                            # controlling screen
                                                            # and keyboard
                                                            # brightness, etc.

NVidia Driver Support for the Additional Display

The Nouvea drivers[4] seem to work well for screen modes up to the MacBook Pro’s native screen resolution of 1440x900. However monitors having a resolution greater than this seem to exhibit flickering and tearing. To fix this, install the correct version of the NVidia graphics drivers.[5]

Install all updates, and add the RPMFusion repo that contains the nvidia drivers.

$ sudo dnf update
$ sudo dnf install https://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-$(rpm -E %fedora).noarch.rpm https://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-$(rpm -E %fedora).noarch.rpm
The Macbook Pro 2009 15" requires the oldest nvidia-340xx series drivers.

You can use lspci to list the model of graphics hardware.

Setting the timezone

To set a valid timezone

Swap CAPS and Control

Log out and back into i3wm for an updated key map to take effect. Or use the HHKB[6] keyboard and skip this section.

Add the following to ~/.config/i3/config
1
2

4
# Swap CAPS_LOCK and R_CTRL
# To get the current key mappings
# $ xmodmap -pke
exec --no-startup-id /usr/bin/xmodmap /.Xmodmap
Create a new ~/.Xmodmap file, swapping CAPS with the right Control key

!
remove Lock = Caps_Lock
remove Control = Control_R
keysym Control_R = Caps_Lock
keysym Caps_Lock = Control_R
add Lock = Caps_Lock
add Control = Control_R

Swap Command with ALT

A typical PC keyboard layout has Control, Windows, Alt, then Space. Whereas Mac keyboards have Control, Alt, Command, then Space.

Because we are running Linux on a Macbook, with Emacs as well as i3wm, we need an adjustment to key layouts. The default modfier for i3wm is Alt which is also the much used META key in Emacs. The Command key (like the Windows key) maps to Super which is almost unused.

We want to swap Alt and Command such that Alt is immediately to the left of the spacebar allowing much easier use with Emacs. Command can then be used as the i3wm default modifier.

The easiest is to use a keyboard with firmware that allows these keys to be mapped on the keyboard itself. The Kinesis Advantage, Happy Hacking, or a mechanical keyboard with reprogrammable firmware.

An alternative is to swap these keys in the /.config/i3/config file.
1
setxkbmap -option altwin:swap_lalt_lwin
  • Swap Command and ALT.[7]

  • Swap Control and ALT.[8]

Lock the screen from a keypress

Add the following to .~/.config/i3/config

1
bindsym $mod+Control+l exec i3lock

Setting the Background Image

The following command creates a ~/.fehbg file to run at i3wm startup
1
$ feh --bg-scale <path_to_background_image>
Add the following to ~/.config/i3/config
1
2
# Set the background image
exec --no-startup-id ~/.fehbg

Font-Awesome

Fontawesome contains the glyphs referenced in my i3status config.

Install the Fontawesome font package
1
2
# Set the background image
sudo yum install fontawesome-fonts

Take note of the version of Fontawesome that is installed as new versions of Fontawesome contain additional glyphs. Also, Fontawesome is distributed as as free and pro versions, with pro containing substantially more glyphs. It’s best to look at the Fontawesome[9] website, choose the version installed and browse the available glyphs. Optionally, install the latest version of Fontawesome manually. Or take a look at NerdFonts.[10].

Use an alternate terminal emulator

Add the following to .~/.config/i3/config

(Optionally) install a command line shell
