kernel options for Synaptics SYN1B7B:01 06CB:2969 UNKNOWN

mshlinux · 08-17-2015, 11:40 PM

my Laptop is Acer E5-471 with left/right-buttonless touchpad.
I install Gentoo for testing on it from existing Arch Linux.
I boot up Gentoo by Systemd-boot method using Arch's kernel.
everything fines.
but I compiled kernels in Gentoo system.
If I boot Gentoo up using kernel I compiled in gentoo, my touchpad doesn't work.
I have compiled 50+ kernels in only 3 days. No success.
If I boot Gentoo up using Arch's kernel, touchpad works and everything fines.
When so, I check my hardware. "lspci" not shows my touchpad.
but

Code:

$ dmesg | grep input

shows my touchpad like this:

Code:

[    9.767293] input: SYN1B7B:01 06CB:2969 UNKNOWN as /devices/pci0000:00/INT33C2:00/i2c-0/i2c-SYN1B7B:01/0018:06CB:2969.0003/input/input13

and

Code:

$ cat /proc/bus/input/devices

shows my touchpad like this:

so, please suggest for kernel configuration.

sure, I followed Synaptics page of Gentoo.
and tried with hid_multitouch and i2c_hid enabled and followed some online threads.
and also tried with all options under Device Drivers-->Input Device Drivers-->Mice-->
and of course, I have

Code:

# genkernel all

but my touchpad never works.

As the two kernels work differently, a diff of their respective config files could help.

Of course, sort the files first.

Also, it will be easier to analyze if the two kernels have the same version.

thanks for reply.
Yes, I will give a try with same kernel version.
