[Solved] New Kaby/Skylake Laptop - Sysrcd Boot - No Mouse

I've have a new Clevo P750DM2-G laptop which I booted with both the 4.9.2 SystemRescueCd, (Fearedbliss' ZFS version), and the Ubuntu 16.10, ISOs. The 4.9.2 SystemRescueCd would not load the DE GUI unless I selected the Alternate Kernel option.

However, once in the DE, (Gnome in Ubuntu, and XFCE in SystemRescueCd), my trackpad doesn't work correctly. The pointer is pegged in the upper right corner and won't move, although if I move my finger across the trackpad and then click the right click button, the right click popup menu will appear somewhere else on the screen. I tried booting both ISOs' kernels with the "i8042.nomux=1 i8042.reset" command line switches, but it didn't make any difference.

Kernel config
dmesg output
Xorg.0.log

(I believe on an unrelated note), while examining the dmesg output, I noticed PCIe Bus Error messages which led me to this Ubuntu bug report, and after I booted the kernel using the "pci=noaer" command line switch, they no longer appear. However, reading the thread I noticed this comment which concluded with;

MY opinion on this topic:

You should first proper set up your box.

Thanks..

I agree that my best option is go ahead and install Gentoo using the handbook, (and standard options like ext4 fs), and then narrow down any issues, one by one. I appreciate you sharing that methodology with me, as it may likely be the one I need to use to fully debug things.

Lastly, when I booted the Ubuntu 16.04 ISO, I had to set the kernel option nomodeset for the Gnome DE to come up, but the mouse/trackpad worked correctly then. Perhaps this input device issue was one that was more recently introduced. Anyway, I'm off to debug now.

I believe that this is an issue with the current nouveau driver, 1.0.13.

I installed Gentoo following the AMD64 Handbook, with the Desktop Profile and the recommended defaults. I also configured the in kernel nouveau driver, and emerged the xorg server with twm. Starting the x server brought up the desktop screen with the same behavior as noticed when booting Ubuntu 16.10 and the SystemRescueCd 4.9.2 Alternate Kernel. The mouse cursor is stuck in the upper left screen corner, although I can move the actual pointer, just not the on screen icon. Using the touchpad and then trying both the right and left buttons, I would see menu screens popup, on different parts of the screen, and in the twm desktop by slowly tracing on the touchpad, I could see I was enabling focus in the different terminal windows.

I then switched from nouveau to the nvidia-drivers-378.09, and after some minor headaches during this reconfiguration process, starting the x server and bringing up the twm desktop, provides me with full mouse movement again.
