Hello, I'm new to xmonad and I observe a strange behaviour with the status bar. I started xmobar as follow: in my xmonad.hs I have: main = do xmproc <- spawnPipe "xmobar" xmonad $ azertyConfig { workspaces = myWorkspaces, terminal = myTerminal, modMask = myModMask, logHook = dynamicLogWithPP $ xmobarPP { ppOutput = hPutStrLn xmproc, ppTitle = xmobarColor "green" "" . shorten 50 }, manageHook = manageDocks <+> myManageHook <+> manageHook azertyConfig } in my .xmobrrc I have: Config { font = "-misc-fixed-*-*-*-*-10-*-*-*-*-*-*-*" , bgColor = "black" , fgColor = "grey" , position = TopW L 90 , lowerOnStart = True , commands = [ Run Weather "LFLG" ["-t","<station>: <tempC>C","-L","18","-H","25","--normal","green","--high","red","--low","lightblue"] 36000 , Run Network "eth0" ["-L","0","-H","32","--normal","green","--high","red"] 10 , Run Cpu ["-L","3","-H","50","--normal","green","--high","red"] 10 , Run Memory ["-t","Mem: <usedratio>%"] 10 , Run Swap [] 10 , Run Com "uname" ["-s","-r"] "" 36000 , Run Date "%a %b %_d %Y %H:%M:%S" "date" 10 , Run StdinReader ] , sepChar = "%" , alignSep = "}{" , template = "%StdinReader% }{%cpu% | %memory% * %swap% | %eth0% | %date%</fc>| %LFLG% | %uname%" } I can see the status bar in a workspace when it is empty but when I start an application (xterm, firefox, ...) the application covers the status bar and therefore I can not see it. I tried to modify lowerOnStart = False but this hides the top of my application. I'm using xmonad 0.9.1-2 and xmobar 0.9.2-1 with ubuntu 10.04. Thanks for your help, Guillaume
