LGB: I'm not sure exactly what you are asking, but nVidia cards could not have AIGLX enabled by default (as I understand it) because one has to install the proprietary drivers before it can handle it. The open nVidia drivers, which come with Ubuntu, are not that great.
The Intel graphics drivers, on the other hand, are open source and come with Xorg. -- AIGLX is not turned on by default for 855GM cards https://launchpad.net/bugs/61420 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
