[xmonad] erratic panel unhide in xmonad + xfce

[Tom Hirschowitz]

Dear all,

I'm using xfce4 with xmonad and panel autohide. The problem is that,
depending on which windows are present, the panel sometimes does not
unhide. In my experience, it only unhides to cover windows that were
spawned after it. E.g., if it doesn't unhide over a given window and I
restart it, then it does unhide fine.

Snippets of my xmonad.hs are included below.

Does anyone have an idea how to sort this out?

Thanks,
Tom

Thanks! That did simplify things.

However, it doesn't seem to solve the original problem.

Any more hints?

For several years now, xfce4-panel has required ManageDocks' docksEventHook
to function properly.
Also note that, from xmonad 0.12 on, you need more than manageDocks and
avoidStruts in *all* cases: you need both docksEventHook and (as of 0.13)
docksStartupHook as well. Starting in 0.13 we recommend using the new
"docks" combinator instead of the individual hooks. (You would compose it
with the "ewmh" combinator in your config. Speaking of which... why do you
explicitly use ewmhDesktopsLogHook and ewmhDesktopsEventHook? "ewmh"
already adds them. (Fullscreen is not added automatically, because you
might choose to use XMonad.Layout.Fullscreen's fullscreen event hook
instead which provides more control by communicating with its layout hook
instead of just making the window a full screen float.)
