 Posted: Thu Sep 02, 2021 9:47 pm Post subject: [SOLVED]Configuring xinput/libinput parameters for touchpad. |
 |
|
[SOLVED]: Rebuilt the kernel using genkernel all and the default install kernel and my mouse works properly again. I must have disabled an important kernel module on a previous build.
EDIT: The critical module was HID_MULTITOUCH. It lists right in the description it is for several models of touchpad, including the Elan Microelectronics touch panels, which I believe is the model used in the Lenovo Legion 5. Rebuilding the kernel with HID_MULTITOUCH as a module results in the expected, sane touchpad behaviour when controlling the mouse.
Hi everyone, I've had quite a bit of trouble configuring my Lenovo Legion 5 Touchpad so that the mouse is usable. Movement of the mouse pointer is extremely sensitive and 'chunky'.
I have identified my mouse by running xinput --test "MSFT0001:00 06CB:7F28 Mouse" and it does produce output when I interact with the mousepad, including movement in the X and Y directions and detecting button 1 and button 3 press/release.
Output of xinput --list --long "MSFT0001:00 06CB:7F28 Mouse":
| Code: | MSFT0001:00 06CB:7F28 Mouse id=14 [slave pointer (2)]

| Code: | 1 feedback class

Despite this modification, to accelNum, accelDenom and threshold, the mouse continues to fly around the screen and is unusable.

After setting the following to 0, 0, the mouse movement is still very chunky and imprecise, it is very difficult to click on buttons/hyperlinks/scrollbars, etc:
libinput Accel Profiles Available (324): 1, 1
libinput Accel Profile Enabled (325): 1, 0
I think the problem has something to do with the sensitivity of my trackpad; when I run xinput --test -proximity "MSFT0001:00 06CB:7F28 Mouse" I get the following error:
| Code: | X Error of failed request: XI_BadClass (invalid Class parameter)
Major opcode of failed request: 131 (XInputExtension)
Minor opcode of failed request: 6 (X_SelectExtensionEvent)
Class id in failed request: 0x740
Serial number of failed request: 19
Current serial number in output stream: 19 |
I cannot figure out how to adjust the sensitivity of my trackpad using xinput. Does anyone have any thoughts?
This is the output of sudo libinput list-devices
| Code: |
Device: MSFT0001:00 06CB:7F28 Mouse
Kernel: /dev/input/event9
Group: 6
Seat: seat0, default
Capabilities: pointer
Tap-to-click: n/a
Tap-and-drag: n/a

Nat.scrolling: disabled
Middle emulation: n/a
Calibration: n/a
Scroll methods: button
Click methods: none
Disable-w-typing: n/a
Accel profiles: flat *adaptive
Rotation: n/a |
There are a number of things I would like to modify here, particularly "Accel profiles" and "Disable-w-typing" but it doesn't seem possible with xinput: I get the following error:
xinput --set-prop "MSFT0001:00 06CB:7F28 Mouse" "Disable-w-typing" 1
| Code: | | property 'Disable-w-typing' doesn't exist, you need to specify its type and format |
Is this a case of using an inappropriate command? Or do I need to supply a type and format to adjust this (I don't know what that means in this context).
I have also tried setting libinput values in /etc/X11/xorg.conf.d/50-touchpad.conf, but none of the values I set seem to affect the device's values upon running libinput list-devices. I think I need some guidance regarding managing xinput/libinput devices as I have read the respective handbook pages and archwiki pages and am still confused.
Any help would be greatly appreciated!

Hi. This is not so much likely, but hoping it can help, in particular if it's a Lenovo...
Grep your kernel message (dmesg, /var/log/message or somewhere else) for the word "psmouse". If there's a line something like:
psmouse serio2: synaptics: Your touchpad (PNP: [device ids]) says it can support a different bus. [snip]
then try rebooting with the boot parameter
psmouse.synaptics_intertouch=1
Regards.

Hi Teika, thanks for your input. grepping my dmesg output gives no hits for 'psmouse'. I have rebuilt the kernel with everything under device drivers/input/mice enabled and the touchpad problems persist.
I am also unable to see the touchpad using libinput measure touchpad-pressure - I get the message:
| Code: | | Unable to find touchpad device. |

Hi. This is a known problem (since a year ago), and there seems to be a fix. Simply do a web search for the words: "Lenovo Legion 5 Touchpad linux " or so.
# Seems like a common Gentoo user pitfall, tending to think they can handle problems by examining the kernel config, xinput or else. ;-)
Hope you can fix it soon. Regards. |

Thanks Teika! I'm familiar with those threads concerning the Legion 5 Touchpad not working on Linux, but I thought I had read it had been fixed in a kernel update. I'll look into it again and if I really have to go nuclear, I can always reinstall gentoo to my laptop (the touchpad worked fine for the first month I had gentoo installed, it broke after an update). That would give me a chance to make some other changes I would like (change fs to btrfs, etc ...).
I am going to try rebuilding my kernel with genkernel to basically move back to the default 'full' kernel, I can always shave it back down again if it works.
Thank you for your suggestions anyhow.
EDIT: Haha! Rebuilding the kernel with genkernel all and the default kernel gives the expected trackpad behaviour. I will have to pare it down again to see how much I can remove while preserving touchpad funciton. |
