Please confirm that you have the latest firmware for gp107 (as there was a window of time when linux-firmware contained bad firmware for gp107 -- some time ago now already, but you could have a bad snapshot). I believe I've seen this before though, also on a laptop. I see that it's using the fancy new thing instead of ACPI DSM for powering it on: Jul 11 16:14:58 endless kernel: VGA switcheroo: detected Optimus DSM method \_SB_.PCI0.PEG0.PEGP handle Jul 11 16:14:58 endless kernel: nouveau: detected PR support, will not use DSM Can you try to boot in a way that forces the ACPI stuff to be used? I think pcie_pm_port=off is the thing. And nouveau.runpm=0 for good measure.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
