kde - Synaptics 触摸板在登录后禁用

Question

我在 NixOS 上使用 Plasma5 在 KDE 上，由于某种原因，我的触摸板在使用 KDM 登录后禁用。这是启动后的输出synclient -l。什么会导致这个问题？任何指导将不胜感激。

Answer 1

Having the same problem with KDE on debian with my t440p and opened an issue for the synaptics package. https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=770923

But I found a workaround in the ubuntu forum to use "imps". It has the disadvantage that you can't disable the touchpad an the virtual buttons separately. Better than nothing. Maybe it might help you too.

Try:

sudo modprobe -r psmouse
sudo modprobe psmouse proto=imps

Answer 2

在您的 grub 文件中进行一些更改：

1.sudo nano /etc/default/grub
2.将“i8042.notimeout i8042.nomux”添加到显示 3.GRUB_CMDLINE_LINUX=”...”的行中。
4.sudo update-grub
5.sudo apt-get install kde-config-touchpad && synaptiks

编辑触摸板文件：
6.sudo nano /etc/pm/sleep.d/restart_touchpad.sh
7. 输入以下代码：

         #!/bin/sh

         case “$1” in
           resume)
               modprobe -r psmouse
               modprobe psmouse
         esac
         exit 0

7.sudo chmod +x /etc/pm/sleep.d/restart_touchpad.sh
8.sudo 重启。
正确执行所有步骤。
