Default How can I use OpenGL 3.2 new function?

I want to use glXCopyImageSubDataNV with Linux and dual graphic cards.
I have installed driver 190.40 and it seems to work properly for conventional functions, but not for this new function. The error is always BadMatch with glXVendorPrivate, even if strange context or texture parameters are intentionally given.

Should I get other package than the latest nvidia driver for using this new function? For example, I found that the glxext.h and glext.h are not same as those on opengl.org, and missing some definitions necessary for glXCreateContextAttribsARB.

Thank you very much for information.
I apologize for that I posted similar question to forum on OpenGL.org as well.

Thumbs up Problem Resolved!!

AaronP,

Thank you for your reply.
The problem was resolved during arranging my program to post upon your suggestion. I am sorry for disturb you and other readers by my careless mistake.
The cause was that one texture was not properly related to the context, in other word,
the source context and source texture are not match. I found that even glXCreateContextAttribARB is not necessary, and glXCreateContext is OK.

The performance of the glXCopyImage is wonderful! Thanks a lot for nVidia!
