I am looking for a laptop that I can use for blender on linux and for gaming in windows. The Sager NP7950 (aka Clevo N950K6?) caught my eye, but I have not been able to find out any information about how well-supported its hardware is by linux drivers. I know that the Alienware 15 I tried did not even have HDMI audio without PCI tricks ( https://unix.stackexchange.com/a/394725/154635 )

Would someone with this laptop answer with the output of lspci -v and the kernel version? (even if it is just from a live DVD). And if you actually installed Linux on this, please point out any speedbumps you encountered.

Using a gentoo live USB stick I was able to collect the following information:

The Chicony might be the webcam. I speculate the Kingston is an SD card reader. The 8087:0a2b Intel seems to be the Bluetooth. Including lsusb -v output would exceed the character limit for stackexchange posts.

It appears the wifi card is not supported in the old gentoo image I used for this test. Once I got gentoo installed and running a recent kernel (4.12.12) I was able to make the wifi work using the iwlwifi driver and a recent set of firmware (emerge linux-firmware).

Another oddity is that the internal flat panel display is connected to the Intel graphics chip, and all the external ports (HDMI + 2DP) are connected to the nVidia. I was able to make them all usable using the Gentoo NVIDIA/Optimus instructions .

Also missing from that lspci output is the PCI device for HDMI audio. To make it appear, you must use the techniques outlined in https://unix.stackexchange.com/a/394725/154635 .
