[SOLVED] Elan touchpad


I bought a Lenovo ideapad 320 laptop.
I installed current and it runs ok. However, having trouble setting sensitivity on the elan touchpad.
Is there a particular driver I need to install for that touchpad?
It shows as Elan 060C.
Oh, I believe it is using the synaptic driver in X.
Thanks.

There's no need to speculate about which Xorg input driver is handling the device. Examine the Xorg log....
Code:
grep "Using input driver" /var/log/Xorg.0.log
Most recent distros/ desktop environments have moved to using libinput. (The evdev and synaptics drivers have been deprecated.)

Ok, that confirms that the synaptics driver is in use for the Elan device. Have you tried using the libinput driver instead? Just a matter of inhibiting it loading via it's /etc/X11/xorg.conf.d/ configuration file (eg rename it or comment the driver entry in it). Sometimes, it's just down to the touchpad hardware design and there's not a lot that can be done.

I can't find that file via slackpkg, neither is installed.

Do see it in sbopkg tho. Will try that.

Thanks

Update: installed, learning and testing libinput.

Can't say libinput is doing any better, but still have different options to try in the config file.

As of about March 1st or 2nd:
# slackpkg search libinput

Looking for libinput in package list. Please wait... DONE

The list below shows all packages with name matching "libinput".

[ installed ] - libinput-1.10.1-x86_64-1
[ installed ] - xf86-input-libinput-0.26.0-x86_64-1

Still need some minor tweaking, but I'm a lot more comfortable with the touchpad right now.
Oh, since using current, the kernel is 4.14.23
