I suspect I need to import something, but what? Here's my xmonad.hs file:

Data.Monoid has both. ps. I found xmonad at github: https://github.com/xmonad/xmonad is this an official repository?

No; some github worshipper took it on himself to fork xmonad onto github on the grounds that any project not on github is obviously dead and unmaintained and it was up to him to "save" it (this is very nearly word for word from the mailing list discussion!), but somehow nobody actually followed him along the path to salvation and it hasn't been updated since he did it. The official repo is still darcs at http://code.haskell.org/xmonad/ and http://code.haskell.org/XMonadContrib. -- brandon s allbery kf8nh sine nomine associates allbery.b@gmail.com ballbery@sinenomine.net unix, openafs, kerberos, infrastructure, xmonad http://sinenomine.net

The module you're looking for is Data.Monoid. I have never really understood xmodmap, and I suspect it's broken in a few ways. You can probably fix your problem by moving numlock to a different keysym, like this: xmodmap -e "keysym Num_Lock = F13" Marshall On Tue, Mar 19, 2013 at 02:59:25PM +0100, Thomas Løcke wrote:

A while ago I wrote a post to this list about the problems that arose when I disabled numlock with xmodmap -e "clear mod2":

I ended up "fixing" the problem in the legacy application, so I didn't have to muck about with xmodmap. Or so I thought. Today it reared its ugly head again, once and for all telling me that I seriously need to _completely_ disable the numlock key.

My first step was to upgrade xmonad to 0.11 and then I tried xmodmap -e "clear mod2" again and of course it still didn't work: My mod key was now non-functional again. /sigh

Next step was to dig out the original suggestion from Adam:

handleEventHook = ( \e -> case e of MappingNotifyEvent {} -> return (All False) _ -> mempty)

I added the above to my xmonad.hs file and then it failed with this:

Not in scope: data constructor `All'

Not in scope: `mempty'

Am I missing some crucial parts?

:o)
