Unable to use wgl direct rendering

Unable to use wgl direct rendering

Hi, all

I got a HP dv4 envy 5306tx laptop with dual cards(intel/Nvidia).
I failed to install NVidia driver in linux, so I have to turn to
cygwin in windows.

I install the latest cygwin-32 and xserver under windows8-64.
But when I started the xserver by 'xwin -wgl -multiwindow', I failed
to start direct rendering. The result of 'glxinfo | grep -i rend' is

direct rendering: No (If you want to find out why, try setting
LIBGL_DEBUG=verbose)
OpenGL renderer string: GeForce GT 650M/PCIe/SSE2

After I export LIBGL_DEBUG=verbose, nothing detail is shown. So I
don't know why this doesn't work and where the problem is.

Any advice will be appreciated!

Direct rendering is not supported on Cygwin; even with hardware 
acceleration enabled, rendering is still indirect.
