It is likely that part of this may be due to memory problems I seem to be

Lester,
Exactly what kind of speedups are you expecting here? AFAIU, the
GLX-accelerated XWin will give you speedup only for programs that use the
GLX extension, which automatically excludes most standard X clients (e.g.,
xterm, emacs, etc). For applications not using the GLX extension, the

Thanks.

glxgears shows a massive speed-up (gears graphic doesn't show on ATI?).

A nice addition to cygwin setup.exe would be a search capability for packages

packages increases it becomes harder and harder to find what you are looking

Mark,
As always, patches are thoughtfully considered (eventually). However,
this may not be as easy as you think, since the package tarballs
themselves aren't downloaded until they are selected by the user in setup.
So, that external search page at http://cygwin.com/packages/ is there

My appologies if this is a FAQ, but I haven't found the answer to this, or

This problem has been discussed before. Search the mailing list
