触摸板使用 libinput 而不是 synaptics 驱动程序

触摸板使用 libinput 而不是 synaptics 驱动程序

我的 lenovo x230 上的触摸板没有运行 synaptics 驱动程序,而我需要该驱动程序来增强其功能。相反,它使用 libinput。如何让 synaptics 驱动程序在启动时获得优先级?

触摸板是(xinput list):

⎜   ↳ PS/2 Synaptics TouchPad                   id=13   [slave  pointer  (2)]

我可以使用以下命令检查它正在使用的驱动程序grep -i "Using input driver" /var/log/Xorg.0.log

(II) Using input driver 'libinput' for 'PS/2 Synaptics TouchPad'

但是,我确实安装了 synaptics 驱动程序(sudo apt install xserver-xorg-input-synaptics):

Reading package lists... Done
Building dependency tree       
Reading state information... Done
xserver-xorg-input-synaptics is already the newest version (1.9.0-1ubuntu1).
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

我可以在 libinput 驱动程序旁边看到 synaptics 驱动程序的配置文件(ls /usr/share/X11/xorg.conf.d/):

10-amdgpu.conf  40-libinput.conf          70-wacom.conf
10-quirks.conf  51-synaptics-quirks.conf
10-radeon.conf  70-synaptics.conf

我的结论是 synaptics 和 libinput 驱动程序都已安装,但出于某种原因 libinput 具有更高的优先级。这很令人困惑,因为据我所知,配置文件的编号越高/usr/share/X11/xorg.conf.d/,优先级就越高,这意味着应该选择 synaptics。

我怎样才能让 synaptics 运行?到目前为止,我尝试将synaptics.conf文件移动到/etc/X11/xorg.conf.d因为 我读到这个目录具有更高的优先级,但这没有奏效。相关部分/var/log/Xorg.0.log

它引用的其他设备文件是什么? 在哪里libinput被选为触摸板驱动程序?我怎样才能被synaptics选中?

编辑:我的 libinput 版本是

kp@kvnp:~$ libinput --version
1.10.4

似乎只有一种滚动方法可用:

kp@kvnp:~$ xinput list-props 16

    libinput Drag Lock Buttons (287):   <no items>

当我尝试在 libinput 中进行两指滚动时,我得到以下输出:

kp@kvnp:~$ xinput set-prop 16 290 1 0 0

答案1

我知道这个帖子很旧了,但是我最近更新到 Ubuntu 20.04 LTS 后也遇到了同样的问题。

我通过改变突触编号优先级解决了这个问题 /usr/share/X11/xorg.conf.d/

就我而言,这是命令的输出ls -1 /usr/share/X11/xorg.conf.d/

10-amdgpu.conf
10-quirks.conf
10-radeon.conf
40-libinput.conf
51-synaptics-quirks.conf
70-synaptics.conf
70-wacom.conf

我使用命令将70-synaptics.conf其更改为30-synaptics.conf

mv 70-synaptics.conf 30-synaptics.conf

这使得它的优先级高于40-libinput.conf。请务必以 root 身份执行此操作。然后reboot

答案2

我重新安装了内核,然后安装了

xserver-xorg-input-multitouch

xserver-xorg-input-mouse

通过允许将触摸板识别为SynPS/2 Synaptics Touchpad而不是 ,解决了此问题PS/2 Synaptics Touchpad。简而言之,我认为内核将触摸板识别为基本鼠标。我不太清楚为什么。

答案3

购买了新的触摸板/键盘,触摸板太敏感,安装了 synaptic 和 evdev.confg
10-amdgpu.conf
10-evdev.conf
10-quirks.conf
10-radeon.conf
40-libinput.conf
51-synaptics-quirks.conf
70-synaptics.conf
70-wacom.conf
libinput.conf 仍然是 evdev 驱动程序的默认驱动程序,尝试“mv 70-synaptics.conf 30-synaptics.conf”没有用,不得不 cd 到“/usr/share/X11/xorg.conf.d”之后“mv 70-synaptics.conf 30-synaptics.conf”起作用了,并且还将 libinput.conf 更改为 70
10-amdgpu.conf
10-evdev.conf
10-quirks.conf
10-radeon.conf
30-synaptics.conf
51-synaptics-quirks.conf
70-libinput.conf
70-wacom.conf
不确定这是否能修复我过于敏感的触摸板/键盘(Perixx PERIBOARD-510H Plus,迷你 USB 触摸板键盘美国英语布局 11005)
设备“SINO WEALTH USB 触摸板键盘”:设备已启用(173):1
但这里的信息非常有用,感谢这里的所有人
刚刚检查了 xinput list-props 11,libinput 仍然是设备驱动程序,哦,
我的操作系统是 ubuntu 22.04.4 gnome 版本 42.9 内核版本 6.5.0-25-generic
