So if you have or buy two cardsI'm one of the lead developers of Puppy. Testing of Xvesa is neglected these days, as Xorg works on all my hardware. So when a new version of Puppy is developed, I don't bother with testing Xvesa. The problem with Nvidia video chips has come up many times on the Puppy forum, so I'll look into putting some support built-in. ....someone will have to give me a Nvidia card for testing
