I would like to be able to have xmonad write the output of its dynamicLogXinerama to a FIFO (that I can then read from a Unity app indicator and thus display the workspaces being currently used). I modified my desktop config so that rather than executing xmonad directly it instead runs a simple wrapper script #!/bin/sh mkfifo /tmp/xmonad-fifo xmonad >/tmp/xmonad-fifo but to my surprise running 'tail -f /tmp/xmonad-fifo' shows no output, while if I simply start xmonad in a terminal I can see it printing information about the workspaces being used to the terminal: [1] [1] [2]1 [2]1 ... It would be awesome if anyone could tell me why xmonad's dynamicLog output is not showing up in the FIFO. xmonad itself is clearly running (from the moment I start reading data from the FIFO.) thanks! ~l
