自从我升级到17.10以来,触摸板的点击灵敏度太低,经常错过我的点击。我知道系统已经确定我的Lenovo Yoga 2具有Synaptics触摸板:
$ sudo evtest
No device specified, trying to scan all of /dev/input/event*
Available devices:
...
/dev/input/event6: Synaptics TM2714-001
...
但是xinput认为这与Synaptics无关:
$ xinput list
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ xwayland-pointer:13 id=6 [slave pointer (2)]
⎜ ↳ xwayland-relative-pointer:13 id=7 [slave pointer (2)]
⎜ ↳ xwayland-touch:13 id=9 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
↳ xwayland-keyboard:13 id=8 [slave keyboard (3)]
$ xinput list-props "xwayland-touch:13"
Device 'xwayland-touch:13':
Device Enabled (119): 1
Coordinate Transformation Matrix (121): 1.000000, 0.000000, 0.000000, 0.000000, 1.000000, 0.000000, 0.000000, 0.000000, 1.000000
Device Accel Profile (244): 0

Device Accel Adaptive Deceleration (246): 1.000000
Device Accel Velocity Scaling (247): 10.000000
并且synclient同意:
$ synclient
Couldn't find synaptics properties. No synaptics driver loaded?
libinput确实知道这是一个Synaptics:
$ sudo libinput list-devices
...

尽管我看不到像旧的X11手指压力属性那样的东西。(libinput measure-touchpad-tap
有趣的是,收集有关时间而不是压力的数据。)
如何提高对水龙头的灵敏度?
gsettings
。我现在看不到压力,但也许是领先。
