Wifi and Touchpad

rfx · Posted: Thu Feb 08, 2024 12:57 pm Post subject: Wifi and Touchpad

Hello everyone,

After a short excursion into gentoo-kernel, I'm back at gentoo-sources. I think the last working version was 6.6 and I reused the .config for 6.6.13.

Now I don't have a network adapter, so no WiFi and I have no idea why it suddenly doesn't work anymore (it worked before, of course).

Secondly (while we're talking about my .config anyway), I would be happy if I could get the laptop's touchpad to work with your help. So far the touchpad works with mouse buttons, but the so-called gesture control (2 fingers scrolling) does not work.

Thanks in advance for your help

.config: https://pastebin.com/1UgE1ZZL

lspci & lsusb give the same output with gentoo-sources as with gentoo-kernel. So all drivers should already be activated, the error must lie somewhere else. Touchpad is Elantech.

rfx,

you will need "lspci -k" to see the loaded kernel modules. I suggest to boot our Gentoo dist-kernel and do also a "lsmod". Notice all modules. Touchpad could be more tricky ... ;-)

I guess you have a notebook (because touchpad) but you miss the most important option for a notebook (depending if AMD or Intel):

now i set "CONFIG_X86_INTEL_LPSS". I used this .config since 6.1 wihtout this

lspci -k

These outputs you will need to do the necessary work: Comparing the modules with your settings in .config.

Be aware that not everything is shown in "lsmod". Why ? Because some modules are configured static into the dist-kernel and you dont see it with lsmod.

Only one example: Your touchpad cannot work without i2c BUT i2c needs PINCTRL ... and you have:

I searched and searched, but can't find why wifi doesn't work. The driver is ok, lspci shows the device (02:00.0 Network controller: Qualcomm Atheros QCA6174 802.11ac Wireless Network Adapter (rev 32))

KDE just don't show networks, the checkbox to activate and deactivate wifi is also not there.

Gentoo-sources: https://ibb.co/WWwFKM6
Gentoo-kernel-bin: https://ibb.co/sqmbF5p

As a test, I activated everything from lsmod in the kernel (everything except snd_...), no change.

The touchpad has been working for a long time, only the gesture control isn't, but that's not important to me at the moment, I just need wifi.

Please help! :o)

Please give us your kernel .config and these three queries: https://wiki.gentoo.org/wiki/User:Pietinger/Overview_of_System_Information

rfx,

could you please explain your problem to me again, because so far I have understood that there is no problem with the dist-kernel, but only with your manually configured one. But you booted the dist-kernel and gave me the queries from it:

Sorry, no problem with gentoo-kernel(-bin). Just with gentoo-sources, here i have no wifi but driver looks good to me (lspci shows the device 02:00.0 Network controller: Qualcomm Atheros QCA6174 802.11ac Wireless Network Adapter (rev 32))

Here the correct Infos:

gentoo-sources-6.5.7/.config: https://pastebin.com/iM5TnVKW

rfx,

I have given you two links ... have you read it ?

LPSS_PCI (or _ACPI) activates in many notebooks some modules. Emerging sys-kernel/linux-firmware is necessary.

Thank you for your effort. Of course I read your links
