There was a (lost) patch that fixed it, unfortunately I don't remember where the place was. Ben should be able to come up with that patch fairly easily. However for the user in question, while the PDISP error dumps went away, the underlying problems remained. Just a thought. [As an aside, Corey, with reverse-prime you should also be able to get all 3 screens up... see <a href="http://nouveau.freedesktop.org/wiki/Optimus/">http://nouveau.freedesktop.org/wiki/Optimus/</a> . Of course nothing is perfect, this also introduces tons of problem for some people. But not others.]</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
