我购买了一款新的人体工学鼠标（这个）并且它的行为很奇怪。
当我开始移动鼠标时，Xorg 的 CPU 使用率急剧上升，导致鼠标移动偶尔不稳定。
此外，它在列表中出现了两次xinput。
我在 IBM ThinkPad P50 上运行 Xubuntu。
$ uname -
Linux ███████████ 4.8.0-52-generic #55~16.04.1-Ubuntu SMP Fri Apr 28 14:36:29 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
请注意，我的人体工程学键盘也显示为指针 - 不确定这是否是问题的一部分（PixArt Gaming Mouse是违规者）：
$ xinput list
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ SynPS/2 Synaptics TouchPad id=16 [slave pointer (2)]

⎣ Virtual core keyboard id=3 [master keyboard (2)]

我正在运行 Nouveau Nvidia 驱动程序。
xinput我尝试过使用以及 以及modprobe drm_kms_helper poll=N和modprobe usbhid mousepoll=...各种值来启用/禁用指针设备。
预计到达时间：我尝试切换到metacity进行窗口管理metacity --replace，但没有成功。
