Using Ubuntu 16.04, nVidia driver 364.19, Linux kernel 4.6.0. I have a P65_P67RGRERA and have been experiencing the same problems:
1. If I go in to the BIOS and set the graphics mode to "DISCRETE", then everything works. 2. If I go in to the BIOS and set the graphics mode to "MSHYBRID", then the nVidia card stays powered on. If I turn off the nVidia card, then certain commands will cause the kernel to freeze (such as lspci and lshw). How I'm turning off the nVidia card: rmmod nvidia_drm nvidia_modeset nvidia_uvm nvidia tee /proc/acpi/bbswitch <<<OFF Eggie: when you're in Intel graphics mode, what's your power consumption? Are you sure the nVidia card is turned off? What do you get in IGP mode when you run: cat /proc/acpi/bbswitch ? At first I thought the issue was resolved for me, but after installing and running powerstat, I noticed power consumption was the same in both IGP and DGP modes (around 27 Watts when idle). After running the above command, I found that the nVidia GPU was still powered on in IGP mode. After a lot of digging around, I managed to turn it off using: rmmod nvidia_drm nvidia_modeset nvidia_uvm nvidia tee /proc/acpi/bbswitch <<<OFF Idle power consumption then halved (to around 13 Watts), but then certain commands cause the laptop to instantly freeze (such as lshw or lspci). -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1569383 Title: Intel HD Graphics 530 crashes on glxinfo in MSHYBRID mode Status in xserver-xorg-video-intel package in Ubuntu: Incomplete Bug description: On my laptop (Clevo P650RA) with Skylake / Intel Core i7 6700HQ with Intel HD Graphics 530 IGP and a nvidia GTX965M DGP, glxinfo crashes when running in IGP mode, The laptop uses Optimus / MSHYBRID technology to be able to utilize both IGP and DGP. After setup I install nvidia-361 driver, which will make the system run using DGP mode by default. Using prime-select intel I can switch to using the IGP. After logging out and in again, the IGP is being used. However, when doing certain tasks, the system will crash. Running glxinfo is one of them. Another one is: cat /proc/acpi/bbswitch In addition, it sometimes seemingly at random, probably when some kind of desktop effect is performed. It seems that some kind of interaction with ACPI / IGP will make it crash. This is running Kubuntu 16.04 Xenial Beta 2.
