Fair enough; I didn't know someone had dropped this alias into section 3; it certainly looks out of place. But I keep well away from X11 calls, and hence libx11-doc, and would advise the OP to do so also: Package: libx11-doc Description-en: X11 client-side library (development documentation) This package provides a client interface to the X Window System, otherwise known as 'Xlib'. It provides a complete API for the basic functions of the window system. This package contains supplemental documentation for the library found in libx11-6. Non-developers likely have little use for this package. Having just looked at the OP again (via the HTML this time), I see there's an external link to that library (which my lynx suppresses). So it's possible the OP hasn't installed libx11-doc. Cheers, David.
