Oh, if you can get to all your outputs from the intel card, but can also get them from the nvidia card, then you do have a hardware mux. My bad. But I think you can still use the xrandr offload stuff in that case, as shown on <a href="http://nouveau.freedesktop.org/wiki/Optimus/">http://nouveau.freedesktop.org/wiki/Optimus/</a>. In the end, what are you looking for from your nvidia card? If it's the occasional 3d game/whatever, you can use DRI_PRIME=1 for that, at which point it should turn on and then turn back off when you're done due to runtime pm. [Make sure that your kernel is configured with CONFIG_RUNTIME_PM.]</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
