因此,我尝试使用配置尽可能小的内核在 Dell XPS 9520 上安装 Gentoo。到目前为止,除了触摸板之外,我已经成功地让一切正常工作。
我已经启动到 Kubuntu 并dmesg

这里04F3:2D24
代表触摸屏和04F3:311C
触摸板,如libinput list-devices
Kubuntu 上所标识的那样。我已经确定(令我惊讶的是)触摸板和触摸屏(即ELAN2D24:00 04F3:2D24
、VEN_04F3:00 04F3:311C Mouse
和VEN_04F3:00 04F3:311C Touchpad
)的驱动程序为hid_multitouch
:
$ ls -l /dev/input/event[...]
[...]
$ cd /sys/dev/char/[major]:[minor]/device/device/driver
[...]
$ ls -al | grep module
hid_multitouch
在 Gentoo 上,我启用了I2C_DESIGNWARE_CORE
,I2C_DESIGNWARE_PLATFORM
并且甚至 I2C_DESIGNWARE_PCI
(当然,还有hid_multitouch
),但无济于事。该模块确实加载了,

但似乎只驱动触摸屏。
更令人好奇的是,Kubuntu 内核似乎在没有驱动程序的情况下运行良好,仅依赖于i2c
和hid
驱动程序(然而,它仍然以某种方式在日志中报告i2c_designware.0
和)。i2c_designware.1
dmesg
当谈到这件事时,我束手无策,不知道如何继续。我对 Linux 还很陌生;非常感谢您的帮助。
编辑:有时,重新启动后,使用触摸板会在 TTY 上产生看似随机的字符流。
答案1
Gentoo 论坛用户的假如以下答案与我链接我自己的问题在那里。备查:
2015 年 5 月 18 日合并的 Alder Lake 引脚控制驱动程序中似乎存在错误。相反,启用 Tiger Lake 驱动程序。另外,仅
- Synopsys DesignWare 平台 (
I2C_DESIGNWARE_PLATFORM
) - HID 通过 I2C 传输层 ACPI (
I2C_HID_ACPI
) 和 - hid_multitouch (
HID_MULTITOUCH
)
驱动程序是必要的。不必要的是:
- DesignWare PCI
- LPSS(通用 I2C 驱动程序)
- 中小企业总线
- 通用输入输出接口
- 输入设备支持
- 触摸屏
- 老鼠和其他司机
