![IdeaPad 5 触摸板无响应](https://linux22.com/image/172501/IdeaPad%205%20%E8%A7%A6%E6%91%B8%E6%9D%BF%E6%97%A0%E5%93%8D%E5%BA%94.png)
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。

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。
