Hello, In case someone is interested, I wrote this little utility in C: https://github.com/jimenezrick/hidcur
It hides the mouse cursor whenever is idle. A good excuse for me to try XCB and to learn a little about X11. Inspired by: - unclutter: http://ftp.x.org/contrib/utilities/unclutter-8.README - hhp: http://hackage.haskell.org/package/xmonad-utils -- Ricardo (http://r.untroubled.be/)
