 Posted: Wed Jul 20, 2022 7:28 am Post subject: Problems with touchpad (solved) |
 |
|
This is silly, but I am having a weird problem with the touchpad on this laptop I am building Gentoo on
It's not being recognized as a touchpad, just as a mouse, and/or a touchscreen.
From hwinfo --short:
| Code: | mouse:
/dev/input/mice MSFT0001:00 06CB:CDB0 Mouse
/dev/input/mice MSFT0001:00 06CB:CDB0 Touchpad
|
Here is what I get in Xorg.0.log:

and from xinput list:
| Code: | ⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ MSFT0001:00 06CB:CDB0 Mouse id=10 [slave pointer (2)]
⎜ ↳ MSFT0001:00 06CB:CDB0 Touchpad id=12 [slave pointer (2)]
|
For the moment I am very confused - can anyone enlighten me?

We had a lot of threads with notebooks using touchpads with an I2C connection ... you probably have.
libinput is correct, but you probably miss some kernel modules/options. One way is to boot a (working) ubuntu live cd and check all used modules with "lsmod". Enable all these in your gentoo kernel ...
Other ways:
1. Search if you find your notebook in https://wiki.gentoo.org/wiki/Category:Laptops and do these kernel settings , OR
2. Try all settings in my german guide for I2C touchpads -> https://forums.gentoo.org/viewtopic-p-8692426.html#8692426 (and forget my german sayings or translate with google) |

I knew that it was an I2C connection. This does seem to trap even the wary sometimes.

I rebuilt the kernel (5.18.12), turning on any reference to ALPS and I2C DesignWare devices.
Touchpad is working now. Now to fix udev so my bluetooth mouse maps correctly for left handed use....
