Hello,
Does the DVD version of Mandriva 2007.1 has Matisse or is just in the Live CD version? I heard conflicting news and am perplexed. From the site of Mandriva also it is not very clear to me. Has anyone tried Matisse in the DVD (Free) version?

I've tried it in the powerpack version, but still can't get it to work.

I did the following, "Opened MCC, went to Hardware then Configure 3D Desktop effects." As soon as I clicked on "Configure 3D Desktop effects" I was immediately logged out of KDE. never even saw what was supposed to be in the dropdown. I tried selecting 3D from the login prompt, but was then prompted for the root password which I supplied. Thereupon, it went back to the login screen again.

Video board and Driver: nVidia GeForce 6600 GT (AGP) (dkms driver 9755)

Have you looked at the mandy wiki?

and the errata that goes with it?

(edit)
I got the 64bit version of One2007.1 (spring, only a cdrom), which had it installed. I installed that then got all the other programs i like from the repos.
