install-dwm-macos-2.md

Installing and configuring dwm on OS X (tested on Mountain Lion, Mavericks).

Several years old. May no longer be relevant.

HowTo

• Install XQuartz.
• Install dwm using Homebrew (or whatever):

        brew install dwm

• Create a xinitrc.d script for dwm:

        mkdir ~/.xinitrc.d
        echo "USERWM=/usr/local/bin/dwm" > ~/.xinitrc.d/00-dwm.sh
        chmod +x ~/.xinitrc.d/*

• Run XQuartz, dwm should start.

Notes

It might be useful to tweak some XQuartz settings (just press ⌘,) like full screen, clipboard, etc.

Install Software

XQuartz

Install XQuartz (http://xquartz.macosforge.org) which is the development version of the X11.app that ships with OS X, which means it is way more up to date. I have had some weird issues with X11.app v. 2.3-something. XQuartz 2.5.0 fixed that.

DWM

Install dwm from Homebrew, brew install dwm. This makes a bunch of necessary tweaks to the DWM configuration.

Configuration

Shell

Add the following script to $PATH, name it dwm-launch and chmod 755:

        cd ~
        while true
        do
          xsetroot -name "`date +"%Y-%m-%d %H:%M"`"
          sleep 5
        done &
        exec /usr/local/bin/dwm

Add the following to ~/.xinitrc:

        PATH=$PATH:/usr/local/bin
        xsetroot -solid '#4a525a'
        exec >>~/.xsession-errors 2>&1
        ~/bin/dwm-launch

Add the following to ~/.Xmodmap:

        remove Mod2 = Meta_L
        add Mod1 = Meta_L

X11 uxterm is launched as a non-login shell, which is undesirable. To launch uxterm as a login shell, add the following to ~/.Xdefaults:

        XTerm*foreground: white
        XTerm*background: black

Start X11

Start X11.app.

dwm should start. You need to change a few settings to make copy/paste between X11 and Aqua work:

• Go to X11 -> Preferences... and enable Emulate three button mouse under Input.
• Next, enable everything under Pasteboard.
• In X11 you copy text by selecting it with the mouse, and you paste by pressing Alt and clicking the mouse.

Issues

After some time you might not be able to open new terminals. This has something to do with permissions, and can be fixed with xhost +. Do you know a permanent solution? (Possibly fixed with one of the settings under X11 -> Preferences… -> Security)
