The VGA/DVI connectors appear to be on the nvidia card -- they're inaccessible from intel, right? (A bit hard to tell from your logs...) So... please try the following: linux 3.13-rc1 -- this has some fixes for nvc1 as well as runtime pm. don't touch bumblebee don't touch vga_switcheroo The nvidia card should automatically suspend when you're not using its VGA/DVI outputs (and not using it for 3d rendering). If you now run xrandr --setprovideroutputsource nouveau Intel you should be able to use your intel card to show images on the nvidia-connected screens. (You can also reverse this logic to use the nvidia card as the 'main' card.)</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
