 Posted: Wed Aug 10, 2022 7:35 am Post subject: Kernel not recognizing touchpad Acer Swift 3 |
 |
|
Hello, I was trying to install Gentoo to my new laptop.
Since I have used Gentoo for quite a time so everything works after a few struggling.
However, I still cannot get my touchpad working, which is supposed to be a ELAN Touchpad.
Kernel continues to recognize it as a "Generic Logitech Mouse", which doesn't support two finger scrolling.
My laptop model is Acer Swift 3 2022 with a I7-1260P.
Here is my

I have also enabled CONFIG_{LPSS, SUNRISEPOINTER, ELAN, I2C...} related kernel configs.
I hope the following is useful.
| Code: |
CONFIG_MOUSE_PS2_ELANTECH=y
CONFIG_MOUSE_PS2_ELANTECH_SMBUS=y
CONFIG_MOUSE_ELAN_I2C=m
CONFIG_MOUSE_ELAN_I2C_I2C=y
# CONFIG_MOUSE_ELAN_I2C_SMBUS is not set
# CONFIG_TOUCHSCREEN_ELAN is not set
CONFIG_HID_ELAN=y
|
Apart from those settings, I have also set "i8042.{nomux...}" without which the "Logitech Mouse" would also disappear.
Thank you very much for you help. |

| Which touchpad is it? Perhaps we are suffering from an identical problem, since you're also on Alder Lake. Mine's a 311C. |

Hi
what is the output of
| Code: |
grep CONFIG_I2C_DESIGNWARE /usr/src/linux/.config
and
grep -i input_dev /etc/portage/make.conf

I have tried a LiveCD of EndeavourOS, the touchpad works fine on it.

⎜ ↳ ELAN050B:01 04F3:312B Touchpad id=11 [slave pointer (2)]
|
This also shows mine is a 04F3:312B? |

This is what i get from dmesg
| Code: |
dmesg | grep -i elan

with

Touchpad works fine.
I am not sure why it fails in your case.
Maybe firmware related?
Try also
Do you have
| Code: |
CONFIG_SERIO_I8042=m

I have tried those without luck.
CONFIG_SERIO_I8042=y on my side, looks like some other config forces it to do so. |

grep -i synaptic /usr/src/linux/.config

Looks good to me? Is there anything that isn't supposed to be enabled? |

I solved this matter in an unreasonable way....
Just enable all CONFIG_PINCTRL_<CPU Gen> under Intel Pin Control Drivers.
Don't just enable Alderlake...
I dnk why, but I am astonished.... |

More specific solution is as to enable ALL the following.
| Code: |
CONFIG_PINCTRL_BAYTRAIL=y
CONFIG_PINCTRL_CHERRYVIEW=y
CONFIG_PINCTRL_LYNXPOINT=y
CONFIG_PINCTRL_INTEL=y
CONFIG_PINCTRL_ALDERLAKE=y
CONFIG_PINCTRL_BROXTON=y
CONFIG_PINCTRL_CANNONLAKE=y
CONFIG_PINCTRL_CEDARFORK=y
CONFIG_PINCTRL_DENVERTON=y
CONFIG_PINCTRL_ELKHARTLAKE=y
CONFIG_PINCTRL_EMMITSBURG=y
CONFIG_PINCTRL_GEMINILAKE=y
CONFIG_PINCTRL_ICELAKE=y
CONFIG_PINCTRL_JASPERLAKE=y
CONFIG_PINCTRL_LAKEFIELD=y
CONFIG_PINCTRL_LEWISBURG=y
CONFIG_PINCTRL_SUNRISEPOINT=y
CONFIG_PINCTRL_TIGERLAKE=y

Have you enabled them as <M>odule ? If yes, what shows "lsmod" ? Maybe you need another module than alderlake ? |

Sadly, mark them as "M" doesn't work, my guess is that this detection happens in the early stage of booting.
I'm currently bisecting to locate the module needed |

|
|
After serveral rebooting, my guess is that just enabling
| Code: | | CONFIG_PINCTRL_TIGERLAKE=y |
is sufficient if you're using AlderLake(12 Gen)/TigerLake(11 Gen).
One possible reason for this strange case is that "AlderLake" Pinctrl Driver isn't fully ready or contains potential bugs?
Anyway, case solved.
Thanks! |

| May I ask how you figured this out? I didn't even hesitate to enable only the PINCTRL_ALDERLAKE pin controller. |

LOL, tried everything around ELAN|SYNAPTICS|LPSS|...
Then I try to enable all related options, if not working then only keeps necessary ones...
Luckily it worked, when it comes to Pinctrl Driver.
Just one final desprerate try(if not working, I will just go get some binary kernel...) |
