Nope, that's expected. Something weird with the PMPEG unit on the cards. Although usually the errors happen just once at boot... dunno. And to further clarify, you get the corruption as in the photo no matter what once you enable the second screen? Given what the photo looks like, seems like there's an issue with strides... perhaps the fb stride isn't being propagated properly? All the dispnv04 code is pretty much stuck in antiquity unfortunately =/ And none of the PRIME stuff has been tested with pre-G80 GPUs.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
