当指针绕圈移动时,Xorg 的 CPU 利用率为 99%;指针设备出现两次

当指针绕圈移动时,Xorg 的 CPU 利用率为 99%;指针设备出现两次

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):

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=Nmodprobe 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。
