Supposedly, it is faster to use X input rather than GL input because X input
is implemented through an asynchronous process. However, in my personal
testing, I have not noticed ay difference, but it may be because I do not
keep my fingers on the keyboard continuously. This was on both an Onyx-4
and an Indigo2 Extreme (running 5.2 and 5.3, respectively). The problems
with X are that it is much more difficult to get started (despite the
abundance of code available), there are bugs in the Indigo implementation
(according to the release notes), and you cannot easily use window events
and stuff unless you are an expert in X (I am not an expert and I tried and
couldn't get it done, merely pushing/popping the window, and moving it).
Of course, I posted the question here and someone respond, but apparently it
is still impossible to push/pop/move a GLX window. Also, the ctrl, shift,
and alt keys aren't polled in X.
