 Posted: Thu Jan 05, 2023 3:34 pm Post subject: <SOLVED> Huawei Matebook pro trackpad troubleshooting |
 |
|
Trying to get X fully working on a fairly new ultra portable laptop. The laptop has a bunch of devices I am not familiar with from previous gentoo builds over the years.
So far, I've gotten everything working except for the trackpad under X. Looking for ideas on what I might need to add to either my kernel or X USE flags.
Here's a lspci dump of the system. It's all the sunrise stuff that I dont recognize. I assume I havent compiled something important.

Be sure to enable Designware PCI, LPSS, a valid pin controller and I2C HID to have a chance to get this working. Possibly additional trackpad options for I2C.
The trackpad is almost never on the PCI bus. Often it will be on USB or I2C on modern systems. Older ones have it on the PS/2 bus. |

JumboAg,
Pastebin your dmesg output please. This will show what the kernel did when it started.
Pastebin your kernel .config too please. It will probably need to be changed.

That was it, thank you. I had several IC2 options already but was missing the appropriate Pin Controller. |
