双启动：每次Windows启动时，都会增加Ubuntu上鼠标的滚动速度
我的朋友有微软无线桌面850和AES（PY9-00001） Ubuntu 18.04。 滚动速度太快，但如果他移除USB加密狗并重新插入，它可以解决问题 。
他使用双启动PC，每次启动Windows然后重新启动回到Ubuntu，问题就出现了。
我们怎样才能把它修好？
仅在软重启后才会出现此问题。
当鼠标工作正常时lsusb
lsusb当它不工作时，启动Windows然后启动Ubuntu
当鼠标按预期工作时， lsmod输出

显然，KISS（Keep It Simply Stupid）答案是：
- 关闭 Windows
- 按电源按钮启动到Ubuntu。
为什么？
Windows驱动程序使鼠标处于不稳定状态，并且没有一个真正聪明的答案似乎工作，这使我得出Ubuntu无法解决此Windows问题的结论。
你仍然可以向驱动程序的开发人员提交一个错误（这里是偏离主题的），但这是一个副作用，而且众所周知难以调试。 如果你这样做，期望花很多时间在这上面
重置鼠标
Windows有重新启动时将设备置于exception状态的习惯。 当您从Windows重新启动到Windows时，它可以正常工作，但是从Windows重新启动到Grub然后重新启动到Ubuntu时会出现问题。
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关闭音频卡，WiFi或网络适配器也可能发生。
这是我测试过的一个新脚本，并没有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
将文件标记为可执行文件：
sudo chmod +x /usr/local/bin/reset-usb
编辑文件/etc/rc.local并在表示exit 0的最后一行之前插入这些行：
# Reboot / reset all USB devices /usr/local/bin/reset-usb
Credit ： 如何从命令行重置USB设备？
注意：重置内部USB设备时，将重新初始化WiFi /蓝牙，以便systemctl restart NetworkManager 。
鼠标必须具有DPI设置，以便在启动时修改窗口。 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。
当您在没有重启电源的情况下重新启动回Ubuntu时，DPI设置仍然处于Windows设置的水平。 但是，Ubuntu默认情况下将鼠标加速设置为大于x 1的速度，因此您可以体验到更快的运动。
您可以在Ubuntu中删除鼠标加速，以便您可以在Windows和Ubuntu之间切换以获得类似的鼠标移动速度，但如果直接打开Ubuntu，您可能会获得非常慢的鼠标移动，除非您的鼠标支持DPI设置内存不会改变超过电源循环。
在Ubuntu中删除鼠标加速，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投入使用（即注销/登录）
