I started a brief migrating to modular X howto, on popular demand.
Comments and additions would be appreciated.
Just a quick note for any brave amd64 users who might want to try this, it
seems that something isn't quite right as all X apps seem to cause BadValue
X errors in XCreateWindow.
I'm unsure as to whether I've done something wrong, or this is a problem
upstream.
I haven't given it a try on my athlon64 yet, but if you could take a
look at https://bugs.gentoo.org/show_bug.cgi?id=100767 and see if it
could be in any way related.
I don't think it's the same problem, but it could possibly be something
similar?
I've attached a small test case which demonstrates a problem with event
selection.
I haven't had time yet to try this with XCreateWindow also, but I
imagine I'll see
similar results if I try to select for events on the window. I'll try
and track this down
sometime in the next 24-hours, and report upstream if it is indeed a
problem there.
