双启动：每次 Windows 启动时，它都会增加鼠标在 Ubuntu 上的滚动速度

772

我的朋友有带有 AES (PY9-00001) Ubuntu 18.04 的 Microsoft Wireless Desktop 850。滚动速度太快了，但是如果他将USB加密狗取下并重新插入，它就可以解决问题。

他在双启动 PC 上，每次启动 Windows 然后重新启动到 Ubuntu 时，问题又回来了。

我们如何才能永久修复它？

仅在软重启后才会出现该问题。

lsusb当鼠标工作正常时

lsusb当它不工作时，在启动 Windows 时，然后是 Ubuntu

当鼠标按预期工作时，lsmod输出

重置鼠标

Windows 习惯于在重新启动时使设备处于异常状态。当您从 Windows 重新启动到 Windows 时它工作正常，但是从 Windows 重新启动到 Grub 然后进入 Ubuntu 时出现问题。

OP的问题只是鼠标滚动速度不正确的一个例子。其他示例包括 Windows 关闭声卡、WiFi 或网络适配器也可能发生。

这是我测试过的一个新脚本，它不会像第一个脚本那样锁定鼠标/键盘。

将此脚本添加到/usr/local/bin/reset-usb：

#!/bin/bash

# NAME: /usr/local/bin/reset-usb
# DATE: August 17, 2018.
# DESC: Written for Ask Ubuntu Question:
#       https://askubuntu.com/questions/1061754
#       Reboots / resets all USB devices including mouse & WiFi

if [[ $(id -u) != 0 ]]; then # root powers needed to call this script
    echo $0 must be called with sudo powers
    exit 1
fi

for i in /sys/bus/pci/drivers/[uoex]hci_hcd/*:*; do
  [ -e "$i" ] || continue
  echo "${i##*/}" > "${i%/*}/unbind"
  echo "${i##*/}" > "${i%/*}/bind"
done

systemctl restart NetworkManager.service

exit 0

使用以下命令将文件标记为可执行文件：

sudo chmod +x /usr/local/bin/reset-usb

编辑文件并在最后一行之前/etc/rc.local插入这些行：exit 0

# Reboot / reset all USB devices
/usr/local/bin/reset-usb

信用：如何从命令行重置 USB 设备？

注意：当内部 USB 设备重置时，WiFi/蓝牙会重新初始化，因此systemctl restart NetworkManager.

显然，KISS（保持简单愚蠢）的答案是：

关闭Windows
按电源按钮启动进入 Ubuntu。

为什么？

Windows 驱动程序使鼠标处于不稳定状态，并且真正聪明的答案似乎都不起作用，这使我得出结论，Ubuntu 无法解决这个 Windows 问题。

_{您仍然可以向驱动程序的开发人员提交错误（这里是题外话），但这是一个副作用并且众所周知难以调试。如果你走那条路，预计会花很多时间在这上面}

鼠标必须具有 Windows 启动时修改的 DPI 设置。通常，为了获得最佳响应，系统将禁用软件鼠标加速并将鼠标 DPI 设置为提供所需移动速度的值。

当您在没有重启鼠标的情况下重新启动回 Ubuntu 时，DPI 设置仍处于 Windows 设置的级别。但是，默认情况下，Ubuntu 将鼠标加速度设置为超过 1 倍速度，因此您会体验到更快的运动。

您可以在 Ubuntu 中移除鼠标加速，以便您可以在 Windows 和 Ubuntu 之间切换以获得相似的鼠标移动速度，但是如果您直接打开 Ubuntu 电源，您可能会获得非常缓慢的鼠标移动，除非您的鼠标支持不会更改的 DPI 设置内存在电源循环。

在 Ubuntu 中移除鼠标加速，创建以下文件：

sudo nano /usr/share/X11/xorg.conf.d/50-mouse-accel-disable.conf

文件内容：

Section "InputClass"
    Identifier "Microsoft Mouse"
    MatchIsPointer "yes"
    Option "AccelerationProfile" "-1"
    Option "AccelerationScheme" "none"
    Option "AccelSpeed" "-1"
EndSection

重新启动会话以使此更改生效（即注销/登录）

双启动：每次 Windows 启动时，它都会增加鼠标在 Ubuntu 上的滚动速度

重置鼠标

为什么？

如何运行 .sh 脚本？

如何安装 .tar.gz（或 .tar.bz2）文件？

如何列出所有已安装的软件包

无法锁定管理目录 (/var/lib/dpkg/) 是另一个进程在使用它吗？
