IdeaPad 5 触摸板无响应

IdeaPad 5 触摸板无响应

我一直在尝试诊断我的笔记本电脑触控板无法正常工作。在xinput中检测到:

$ xinput list
⎡ Virtual core pointer                      id=2    [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer                id=4    [slave  pointer  (2)]
⎜   ↳ USB Optical Mouse                         id=10   [slave  pointer  (2)]
⎣ Virtual core keyboard                     id=3    [master keyboard (2)]
    ↳ Virtual core XTEST keyboard               id=5    [slave  keyboard (3)]
    ↳ Power Button                              id=6    [slave  keyboard (3)]
    ↳ Video Bus                                 id=7    [slave  keyboard (3)]
    ↳ Video Bus                                 id=8    [slave  keyboard (3)]
    ↳ Power Button                              id=9    [slave  keyboard (3)]
    ↳ Integrated Camera: Integrated C           id=12   [slave  keyboard (3)]
    ↳ Ideapad extra buttons                     id=13   [slave  keyboard (3)]
    ↳ Intel HID events                          id=14   [slave  keyboard (3)]
    ↳ Intel HID 5 button array                  id=15   [slave  keyboard (3)]
    ↳ AT Translated Set 2 keyboard              id=16   [slave  keyboard (3)]

我尝试将以下命令的变体添加到我的内核参数中:

GRUB_CMDLINE_LINUX="psmouse.synaptics_intertouch=0"
# psmouse.elantech_smbus=0"
# i8042.noloop i8042.nomux i8042.nopnp i8042.reset"
# i8042.nomux=1

注释行是以前的尝试。

据我所知,我认为这是一个 elan 触摸板,但如果我运行dmesg | grep -i elan它,它不会返回任何内容。我安装了 synaptic 和 libinput:

$ pacman -Ss libinput
extra/libinput 1.15.5-1 [installed]
    Input device management and event handling library
extra/xf86-input-libinput 0.29.0-2 (xorg-drivers) [installed]
    Generic input driver for the X.Org server based on libinput
$ pacman -Ss synaptics
extra/xf86-input-synaptics 1.9.1-1 (xorg-drivers) [installed]
    Synaptics driver for notebook touchpads

我确实插入了一个光学 USB 鼠标,它可能会显示在此处:

$ lsmod | grep mouse
mousedev               24576  0

和这里:

$ cat /proc/bus/input/devices | grep touch -C 3 
$ cat /proc/bus/input/devices | grep mouse -C 3
P: Phys=usb-0000:00:14.0-1/input0
S: Sysfs=/devices/pci0000:00/0000:00:14.0/usb3/3-1/3-1:1.0/0003:1BCF:0005.0001/input/input8
U: Uniq=
H: Handlers=event8 mouse0 
B: PROP=0
B: EV=17
B: KEY=1f0000 0 0 0 0
$ cat /proc/bus/input/devices | grep track -C 3
$

不然我好像找不到这个触摸板的踪迹了。非常感谢您的任何意见,谢谢。

$ cat /sys/devices/virtual/dmi/id/product_family

更新

我尝试安装 Windows + 一些 Lenovo 驱动程序,我的所有硬件都按预期工作。我将在周末尝试一些其他内核版本并发布我的结果。
