触摸板/指点杆反应过度

触摸板/指点杆反应过度

自从我安装了 Ubuntu 后,我的触摸板就出现了问题。首先在 GNOME/Unity 下,我的触摸板冻结了几秒钟,并出现以下 dmesg 错误:

psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 1

(仅限触摸板/指点杆,但不适用于我的 USB 鼠标)几个月后,我从 Unity 桌面换到了 xfce 桌面,然后又换到了 KDE:我的触摸板和指点杆要么冻结,要么“反应过度”(整个过程直到重新启动):当我触摸触摸板(和指点杆)时,它会通过右键单击或左键单击所有内容,并且光标变得“疯狂”。dmesg:

psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 1

psmouse serio1: bad data from KBC - timeout

我无法通过重新启动 xserver(login-logut)来解决此问题,我必须重新启动 ubuntu 才能使触摸板工作。

但是这是我的 Xorg 日志

我使用的是搭载 Ubutnu 12.10 的 Thinkpad L420。(新内核/全部更新。)我测试了很多东西,比如使用 gpointing-device-settings 设置最低加速度,但对我来说不起作用。

有什么想法可以解决这个问题吗?

我的解决方法:

sudo touch /etc/pm/sleep.d/00_mousereset
sudo nano /etc/pm/sleep.d/00_mousereset

粘贴/输入以下内容并保存:

#!/bin/sh

case "$1" in
        hibernate)
                ;;
        suspend)
                ;;
        thaw|resume)
                sleep 2
                /sbin/rmmod psmouse
                sleep 2
                /sbin/modprobe psmouse
                ;;
        *)      echo "ERROR calling " $0
                ;;
esac

sudo chmod 755 /etc/pm/sleep.d/00_mousereset

保存,下次暂停/恢复时它就可以工作了。
