I have a P65_P67RGRERA with an nVidia GTX 970m. I too have "kind of" got it working by:
1. Installing the 4.6 kernel. 2. Installing the proprietary nVidia 364 driver. 3. sudo prime-select intel 4. Reboot, go in to the BIOS, and select "MSHYBRID" for the Graphics option. 5. Save BIOS changes and exit the BIOS settings (save and exit). 6. Unload the nVidia modules: sudo rmmod nvidia_drm nvidia_modeset nvidia_uvm nvidia 7. Cut power to the nVidia GPU: tee /proc/acpi/bbswitch <<<OFF 8. Make sure the nVidia GPU is turned off: cat /proc/acpi/bbswitch By using the above, my battery life doubles (I'm getting around 4 hours 30 minutes). Unfortunately, while the above will reduce idle power consumption from around 25-30 Watts to around 12-15 Watts, certain commands will cause a kernel freeze (such as lshw or lspci). -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1533221 Title: Booting with intel graphics enabled results in a lockup Status in linux package in Ubuntu: Triaged Bug description: Booting with intel graphics enabled results in a lockup loading lightdm or logging in results in the greeter screen appearing again.
