[solved] Synaptics not working

g63oo · n00b Joined: 30 Mar 2022 Posts: 18

i have a fresh new gentoo install on my laptop, xorg is set up with bspwm and polybar. the last addition I would like to add is my TouchPad working.

i tried following this gentoo guid: https://wiki.gentoo.org/wiki/Synaptics at first, but with little to no success.
then i looked through the forum and tried a few solutions including this one :
https://forums.gentoo.org/viewtopic.php?p=447285 which helped me identifying which event is connected to my trackpad but sadly the download link isn't available anymore so i couldn't follow it through.

now im stuck with the following:
kernel
http://0x0.st/oAiu.txt

my make.conf
http://0x0.st/oAiQ.bin

dmesg | grep i8042
http://0x0.st/oAi1.json

my 50-Synaptics
http://0x0.st/oAij.conf

my 40-libinput
http://0x0.st/oAie.conf

and i found this searching for my modules in xorg. log

g63oo,

what is your exact notebook model ? Have you checked if there is a description here: https://wiki.gentoo.org/wiki/Category:Laptops ?

If not, you should first examine which kind of touchpad you have. Easiest way to do this, is to boot an UbuntuLiveCD and doing these queries:

g63oo,

There are lots of different ways your touchpad can be connected.
USB or I2C are both popular.

Please post the output of

i got the Lenovo Yoga slim 7:
https://www.lenovo.com/in/en/laptops/yoga/yoga-s-series/Yoga-Slim-7-14ARE05/p/88YGS701397

with a mint live cd i checked the following:
lspci-k
http://0x0.st/oAZS.txt

lsmod more
http://0x0.st/oAZQ.txt

dmesg grep input
http://0x0.st/oAZ1.json

i looked through this list https://wiki.gentoo.org/wiki/Category:Laptops already, through other lenovo devices in hope to find a solution.

this is my current kernel config which i did yesterday:
http://0x0.st/oAiu.txt

and just to be sure i made these changes to my grub 2 days ago(nearly at the bottom) :
https://wiki.gentoo.org/wiki/Synaptics

plus here is my lspci - nnk:
http://0x0.st/oAZc.txt

and my installation told me that the command lsusb didn't exist so this lsusb is from a mint live cd i booted on my laptop:
http://0x0.st/oAZm.txt

g63oo,

after checking your kernel config its hard to believe for me you have read the link @luna80 have given you ... This link should help also:
https://wiki.gentoo.org/wiki/Lenovo_Ideapad_Slim_7

OK, now lets start:

In your queries ("dmesg | grep input") you see its an I2C connected touchpad; in your "lspci" you see it needs I2C_PIIX4. I2C is complete missing ! It is an AMD notebook, so you must enable it. All of these are not enabled in your kernel config:

lenovo sold the laptop i got under 2 different names, under the yoga and the IdeaPad.
i didn't knew that and so i didn't thought that https://wiki.gentoo.org/wiki/Lenovo_Ideapad_Slim_7 this configuration would apply.

regarding all the rest it seems i send you an older configuration bc when i ran male menuconf and checked the setup everything was enabled but the Intel sections he had.

here is the "new kernel" :
http://0x0.st/oAiu.txt

it seems like i send the wrong kernel config, bc when i wanted to reconfigure it i only changed a few options from module to build in in order for mine matching the others config.

sadly after checking my TouchPad still won't work

g63oo,

Mabe the kernel .config you posted was the latest but you are not actually running that kernel?

What is the date/time in

g63oo · n00b Joined: 30 Mar 2022 Posts: 18

i ran uname - a and i pasted the right kernel in my last response

and my bad i send the wrong config before, it was a copy i had from a kernel i ran a few days ago

g63oo,

Its always good to check these things. Its easy to forget to mount boot for the kernel install.

Please past your

ok so
here is the lspci - nnk
http://0x0.st/oALG.txt

dmesg
http://0x0.st/oALk.05

kernel:
http://0x0.st/oAiu.txt

for all the other files (lsmod | more,....) which r from a mint live cd, those r posted above

Try adding

g63oo,

When your rebuild your kernel, please turn on

Make that CONFIG_IKCONFIG and CONFIG_IKCONFIG_PROC, the latter of which only becomes visible after the former is enabled. The first embeds the configuration in the kernel. The second exposes that embedded configuration as the file Neddy intends: /proc/config.gz.

g63oo · n00b Joined: 30 Mar 2022 Posts: 18

ok i updated the kernel as suggested

here is the new kernel as from config.gz:
http://0x0.st/oAp6.txt

here is the dmesg
http://0x0.st/oApl.05

sadly enough the TouchPad still won't come alive, could my 50-Synaptics be the problems?

it works!! ^^

not sure why it works now, but whatbi did was, i loaded and older kernel i had saved and changed everything to what was recommended here.
so its the kernel in the paste but from scratch i suppose, plus i removed the extra lines i had added from grub

thx u guys and sorry for the trouble!
