我有一台 Dell Precision 7510,运行的是 Ubuntu 14.04.5 LTS。我最近安装了最新的内核包 (4.4.0-57-generic),安装后,似乎我的笔记本电脑鼠标被检测到的方式不同(以前是 PS/2 通用鼠标)。
我的 TouchPad 似乎没问题,但现在 Stick 的灵敏度/加速度非常高,以至于无法使用,而且我无法降低它。我已将其升高(使用 Stick 设备下的 xfce 鼠标设置),当我这样做时,鼠标实际上会立即从屏幕的一角移动到另一角。
我尝试了以下命令,但没有任何变化:
xset m 0 0
xset m 1/10 0
xset m 1/1000 0
我能够使用 xinput 通过更改“Synaptics Finger”来修改 TouchPad 灵敏度,但这很麻烦。不过这已经足够好了,所以我就不管它了。真正的问题是 Stick;我无法通过任何属性来更改它。见下文:

我再次弄乱了所有的设备加速属性,但无济于事。
在此先感谢大家的任何想法!这让我很抓狂,我可能不得不坚持使用旧的 3.x 内核。
答案1
在安装了基于 ubuntu 的发行版 (16.04) 且内核为 4.8.0-53 后,我的 7510 也遇到了类似的问题,而我之前安装的较早内核的电脑上没有出现这个问题。
通过调整以下内容,我让轨迹点工作得更好:
Device Accel Profile (264): 2
Device Accel Constant Deceleration (265): 6.000000
Device Accel Adaptive Deceleration (266): 1.000000
Device Accel Velocity Scaling (267): 10.000000
对于遇到此问题的人,您可以通过输入以下内容尝试不同的值:
xinput set-float-prop 'AlpsPS/2 ALPS DualPoint Stick' 'Device Accel Constant Deceleration' 6
...然后通过以下方式使更改永久生效:
echo "xinput set-prop 'AlpsPS/2 ALPS DualPoint Stick' 'Device Accel Constant Deceleration' 6" >> ~/.xsessionrc
我仍然对触控板有意见,它非常敏感,我打字时经常会发出咔嗒声。使用指点杆和中键时,我对滚动速度也不满意,它有点太敏感了。但使用上述设备时,指点杆工作得很好。
答案2
我也遇到了同样的问题。我将“设备加速配置文件”值更改为 -1,这似乎有所帮助。但仍然太敏感了。
答案3
不知道这里的发帖人是否对此有其他想法。我找不到其他错误报告。我也遇到过这个问题。我几乎只使用指点杆。触摸板现在对误点击和滚动也非常敏感。我不得不禁用两指滚动才能使用,而且没有针对指点杆的解决方法。
同时,我计划在此更新之前启动旧内核(4.4.0-47)。
仅供参考,我提交了一个错误:https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1657553
