Quoting Toni Cebrián <ancechu@gmail.com>: * The volume control is missing. Perhaps this is something related to gnome and/or unity but, how do you control volume with trayer or any other similar program? You might like <http://dmwit.com/volume>. I haven't updated it yet to talk about the 0.10 release, but the instructions should be nearly identical; the only difference is that you may use "cabal install" for everything instead of grabbing the development versions from darcs. * I'm using the same configuration file that I was using with Ubuntu 11.04 (http://www.tonicebrian.com/2011/09/05/my-working-environment-with-xmonad/),b... windows do not take the full screen real state (take a look at the attached picture where you will see a strip at the right of the screen not filled with the thunderbird window). What could be wrong with xmonad for not taking that space? Is it possible that one of the things you're starting is setting a strut along the right side of your screen? Perhaps trayer? (xprop will answer this conclusively; send us the output of xprop after you click on trayer and we can help you interpret the output.) ~d
