I installed xmonbar and try to launch it.

xmonbar &

I got Stopped. I don't know what's wrong. Here is my .xmobarrc

Config { font = "-misc-fixed-*-*-*-*-13-*-*-*-*-*-*-*"
   , borderColor = "black"
   , border = TopB
   , allDesktops = True
   , overrideRedirect = True
   , persistent = False
   , hideOnStart = False
   , bgColor = "black"
   , fgColor = "grey"
   , position = TopW L 100

   , lowerOnStart = True
   , commands = [ Run Cpu ["-L","15","-H","50","--normal","green","--high","red"] 10
                , Run Date "%a %b %_d %Y %H:%M:%S" "date" 10
                , Run StdinReader
                ]
   , sepChar = "%"
   , alignSep = "}{"
   , template = "%StdinReader% }{ %cpu% | %date%"
   }

By the way, I'm running xmonad window manager. It works well.

  • xmonbar must be started by xmonad to work properly. Can you post your ~/.xmonad/xmonad.hs as well?

  • @D_Bye Thank you. I've post my xmonad.hs file. It is quite similar as the template file. And I didn't know how to get xmonad work with xmobar.

The bar is stopped because you are starting it as a background job but it is configured to read from stdin (standard input). The xmobar process is not terminated, you should still see the bar.

If the bar is not visible at all, it could be because it is covered by your desktop. You are already importing XMonad.Hooks.ManageDocks and using avoidStruts so you could also use the manageDocks hook it provides and make xmobar behave like a dock (overrideRedirect=False in the configuration).

You configured xmobar to read from standard input, so you should have something writing to its standard input. It can be anything, not necessarily xmonad.

You don't have to start xmobar from xmonad, but if you want to show the output provided by XMonad.Hooks.DynamicLog for instance, it's easier to start it from there.

You can use the xmobar convenience function, as explained in the doc :

main = xmonad =<< xmobar myConfig

Or you can use the statusBar function and define your own pretty printing format :

main = xmonad =<< statusBar "xmobar" myPP myToggleKey myConfig

Or directly use dynamicLogWithPP as shown in the example in the documentation :

main = do
    h <- spawnPipe "xmobar -options -foo -bar"
    xmonad $ defaultConfig {
      ...
      logHook = dynamicLogWithPP $ defaultPP { ppOutput = hPutStrLn h }

spawnPipe runs the given command and returns a Handle to its standard input, that handle is then used in defining the ppOutput function.

I had a working config, and after some minor changes, could not for the life of me figure out why xmobar was no longer working. The other solutions posted is also important, but what eventually worked for me in this case was to also add lowerOnStart = False to .xmobarrc, so it isn't sent to the bottom of the window stack on start.
