datafatmunger,
That's lsusb. Its lsmod we need to see.
Jaglover,
Maybe I need to play with a few binary distros :)

datafatmunger,
This stands out as being missing from your system. | Code: | pinctrl_sunrisepoint 28672 0
pinctrl_intel 20480 1 pinctrl_sunrisepoint |
Its off in your kernel too.
The symbol
| Code: | │ CONFIG_PINCTRL_SUNRISEPOINT: │
│ │
│ Sunrisepoint is the PCH of Intel Skylake. This pinctrl driver │
│ provides an interface that allows configuring of PCH pins and │
│ using them as GPIOs. |
Gets you pinctrl_intel for free.
The help says | Code: | ┌──────────────────────────── Search Results ─────────────────────────────┐
│ Symbol: PINCTRL_SUNRISEPOINT [=n] │
│ Type : tristate │
│ Prompt: Intel Sunrisepoint pinctrl and GPIO driver │
│ Location: │
│ (1) -> Device Drivers │
│ -> Pin controllers │
│ Defined at drivers/pinctrl/intel/Kconfig:67 │
│ Depends on: PINCTRL [=n] && ACPI [=y] │
│ Selects: PINCTRL_INTEL [=n] |

datafatmunger,
Are the modules loaded?

I built them into the kernel, not as modules...so I don't expect to see them with lsmod. Correct?
| Code: |
€ grep CONFIG_PINCTRL_SUNRISEPOINT .config
CONFIG_PINCTRL_SUNRISEPOINT=y
€ grep CONFIG_PINCTRL_INTEL .config
CONFIG_PINCTRL_INTEL=y |
Sanity check:
| Code: | € uname -a
Linux localhost 4.9.16-gentoo #27 SMP Tue Jun 27 07:36:27 CEST 2017 x86_64 Intel(R) Core(TM) i7-7500U CPU @ 2.70GHz GenuineIntel GNU/Linux |
2 things sort of stand out for me at the moment...looking at the work Ubuntu kernel:
| Code: | 00:1f.2 Memory controller: Intel Corporation Sunrise Point-LP PMC (rev 21)
Subsystem: Razer USA Ltd. Sunrise Point-LP PMC
Kernel driver in use: intel_pmc_core
00:1f.4 SMBus: Intel Corporation Sunrise Point-LP SMBus (rev 21)
Subsystem: Razer USA Ltd. Sunrise Point-LP SMBus
Kernel modules: i2c_i801 |
vs. my Gentoo kernel...
| Code: | 00:1f.2 Memory controller: Intel Corporation Sunrise Point-LP PMC (rev 21)
Subsystem: Razer USA Ltd. Sunrise Point-LP PMC
00:1f.4 SMBus: Intel Corporation Sunrise Point-LP SMBus (rev 21)
Subsystem: Razer USA Ltd. Sunrise Point-LP SMBus
Kernel driver in use: i801_smbus |
I think I had the i2c_i801 driver at some point...so maybe i can find that again. The PMC thing I don't get...I have:
| Code: | | CONFIG_INTEL_PMC_CORE=y |
|

datafatmunger,
In your last dmesg, intel_pmc_core tried to load but gave an Error -22.
That's power management. On your RAM controller, its unlikely to affect the touch pad.
I don't know the difference between i2c_i801 and i801_smbus.
Correct. Builtins do not appear in lsmod.
Its possible that Ubuntu has out of tree kernel patches. I would be tempted to drop the Ubuntu .config into a gentoo kernel, run make oldconfig, then build and test the resulting kernel. If that works, you know its a kernel .config issue. It would be better not to build the kernel and any initrd with genkernel.
If that fails, look for out of tree patches.

Hey, datafatmunger,
have you succeed in making those touchpad working? I have RBS late 16 with same problem here: working touchscreen but not touchpad.
Looks like libinput sees it in list of devices but no data incoming. |

datafatmunger,
I've taken kernel config from systemRescueCD and merge it with mine one. Touchpad is working with libinput
So it is definitely some config inside kernel that screw things up. I'll try to find it but I hav eno idea how much time I'll need for this. |
