As for displaying the systray on top of xmobar, I believe trayer can be used to that effect. Here's one example I just found via web search: http://archlinux.me/kofrad/tag/trayer/

Actually, I have just checked how fbpanel behaves with openbox and though
it works as it should, I got the same message

can't chdir to /usr/share/openbox

Yep, that was where I was leading with the comment about strange
assumptions; it sees that there is an EWMH support window with the name
"xmonad" or "openbox" and goes looking for window manager configuration in
a standard location. This probably only works right with desktop
environments, not standalone window managers.

Xfce-panel works correctly with xmonad and displays the ibus status applet but is really ugly when set vertically. I'll stick with xmobar except when I really need this applet.

I have still a question. If I start xmonad and then after xmobar, I got for a little time the situation described in the screenshot (xmobar uses the top of the screen right of the  window title) but soon it is updated and the title of the windows goes under xmobar.
Would-it be possible to get this situation permanently ?

TIA

Alain
