我的问题是鼠标指针速度太高，GUI调整没有效果。我找到了有关使用 xinput 解决此问题的建议。这是我发现的：
nate@Cortana-Mint ~ $ xinput --list --short
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ USB OPTICAL MOUSE id=12 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
↳ Power Button id=6 [slave keyboard (3)]
↳ Video Bus id=7 [slave keyboard (3)]
↳ Power Button id=8 [slave keyboard (3)]
↳ USB Keyboard id=9 [slave keyboard (3)]
↳ USB Keyboard id=10 [slave keyboard (3)]
↳ gspca_zc3xx id=11 [slave keyboard (3)]

如您所见，我没有速度缩放和减速属性，这显然是我应该设置的。“加速速度”已经为 0，所以不确定我能在那里做什么。我尝试通过设置加速，xset但这似乎也没有任何效果。我搜索了有关更新鼠标驱动程序的信息，以防万一出现问题，但除了重新安装 xorg 之外没有找到太多，这听起来不像我想要的。有什么建议么？
