Hi there,

It is probably an LPSS touchpad which is on the I2C bus and needs different drivers, take a look at these topics for info: https://forums.gentoo.org/viewtopic-t-1066604.html https://forums.gentoo.org/viewtopic-t-1066652.html https://forums.gentoo.org/viewtopic-t-1065238.html https://forums.gentoo.org/viewtopic-t-1065156.html

Its actualy the keybord that isn't working, the trackpad works fine.

Sorry, my bad, I'm not sure quite how I managed to misread that so badly .

Are you referring to the keyboard on the "type cover". If so, as of kernel 4.10 a driver lives under the HID_MICROSOFT symbol. https://patchwork.kernel.org/patch/9439493/ That driver might also work for various other MS hid offerings.

Good Luck

well its a surface laptop, its actualy a real laptop with a fixed build in keyboard and not a tablet with a cover keyboard.

could it be it used the same hid then the type cover of the surface 4 pro?

Is the keyboard completely unusable under all Linux kernels you have tested or only unusable under the kernel you compiled as part of your install? If the former, how did you install anything on it? If the latter, you can examine the install environment to see how it operated the keyboard.

[Jeroend]

Yes it works in grub but after that is doesn't do anything, it also didn't work in the rescuecd i used to install gentoo, i had to use an external usb keyboard.

[Hu]

Grub is not Linux, and may be benefiting from some early boot assistance from the firmware. So at this point, we have no indication that any Linux kernel can operate your keyboard. To continue, we need the identifying numbers from the keyboard. Can you post the output of lsusb -v (assuming the laptop keyboard is USB, which it may or may not be)? If the laptop is not mentioned there, check other buses, such as lspci.

[Jeroend]

I found a custom kernel source that should include the keyboard, they use hid_microsoft and #define USB_DEVICE_ID_MS_SURFACE_LAPTOP 0xf001

but i don't seem to have that device:

lsusb:
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 006: ID 1286:204c Marvell Semiconductor, Inc.
Bus 001 Device 002: ID 046d:c52b Logitech, Inc. Unifying Receiver
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Interesting,

The marvell device is your touchscreen but I would have also expected at least a webcam attached by usb. It may be that there is a usb driver missing, or we are looking at the wrong bus entirely. Can you give us a full lspci -k and dmesg please? Maybe we can spot some missing drivers. You can pastebin the dmesg as it will be too long to paste inline (wgetpaste is your friend for that).

here is the lspci: https://pastebin.com/yue5430u
and the dmesg: https://paste.pound-python.org/show/9CSnW5HjQRDMcbMzTooy/

indeed i din't even notice there was no webcam, it definatly has one, could it be that one usb chip isn't supported?

[Jeroend]

well on further invesrtigation the webcam seems to be pcie, and the keyboards seems to be on ACPI, is this supported in the kernel?
