[xmonad] Re: Issue 411 in xmonad: Only one desktop spread over displays instead of two separate with Nvidia Twinview

Comment #10 on issue 411 by vogt.adam: Only one desktop spread over displays instead of two separate with Nvidia Twinview http://code.google.com/p/xmonad/issues/detail?id=411 The xmonad binary can check whether to recompile a config based on the relative ages of current config and the library (object or interface or xmonad.conf). But there doesn't seem to be a distro-independent way to get when the library was installed. Perhaps comparison of output from: ghc-pkg field xmonad id Multiple installs of xmonad (user, global, various versions) complicate the situation, but those tend to be problems in themselves.
