我刚在我的新ThinkPad E460上得到了Ubuntu16.04LTS,它碰巧有一个按钮隐藏在触屏下(就像苹果电脑)。
问题是当我拖放的时候,我点击并按住左边的按钮(在触控板下面),然后移动另一个手指在垫子上。但是ubuntu似乎很困惑,不知道这两个手指中哪一个应该“拖动”,所以鼠标就会跳来跳去。
这个问题是两年前在这篇文章中报道的:联想synaptics按钮死区(单击和拖动问题)但是没有一个解决方案能让我满意:改变AreaBottomEdge并不能解决这个问题,并且软按钮区域已经被定义了,因为Ubuntu正确地将我的触屏识别为一个点击盘,
下面是我对xinput的一些选项:

编辑:我尝试了Ubuntu16.10,结果相同:它在拖放时仍然会跳来跳去。
EDIT2:我也试过Fedora。在Fedora,它正常工作!但是..。我真的更喜欢Ubuntu (我已经习惯了)所以我宁愿使用Ubuntu。尽管如此,我应该在Fedora内部查看哪些配置文件/包版本,以找出可能导致Ubuntu问题的原因?
EDIT3:我查过了,Fedora似乎有版本1.9.0而不是1.8。这可能是不同之处。我似乎无法找到在Ubuntu中安装这个软件包1.9.0版本的方法。

好吧,我找到解决办法了!一直被信任的Debian救了我。我把它留给有同样麻烦的人。
我从Debian中添加了存储库(我相信Debian中也有相同版本的包):
deb http://http.us.debian.org/debian unstable main contrib non-free到/etc/apt/sources.list .列表
那么很明显
sudo apt-get update然后我继续使用synaptic,去掉了下面的包:
Removed the following packages:
ubuntu-desktop
xorg
xserver-common
xserver-xorg
xserver-xorg-core
xserver-xorg-input-all
xserver-xorg-input-evdev
xserver-xorg-input-synaptics
xserver-xorg-input-vmmouse
xserver-xorg-input-wacom
xserver-xorg-video-all
xserver-xorg-video-amdgpu
xserver-xorg-video-ati
xserver-xorg-video-fbdev
xserver-xorg-video-intel
xserver-xorg-video-nouveau
xserver-xorg-video-qxl
xserver-xorg-video-radeon
xserver-xorg-video-vesa
xserver-xorg-video-vmware然后安装了最新版本的Debian版本:
Upgraded the following packages:
libgcrypt20 (1.6.5-2ubuntu0.2) to 1.7.6-1
libinput10 (1.2.3-1ubuntu1) to 1.6.0-1
libwacom-bin (0.18-1) to 0.22-1
libwacom-common (0.18-1) to 0.22-1
libwacom2 (0.18-1) to 0.22-1
Installed the following packages:
libinput-bin (1.6.0-1)
libxcb-util0 (0.3.8-3)
libxfont2 (1:2.0.1-3)
xfonts-100dpi (1:1.0.4+nmu1)
xfonts-75dpi (1:1.0.4+nmu1)
xorg (1:7.7+18)
xserver-xorg (1:7.7+18)
xserver-xorg-core (2:1.19.1-4)
xserver-xorg-input-all (1:7.7+18)

xserver-xorg-input-synaptics (1.9.0-1+b1)
xserver-xorg-video-all (1:7.7+18)

xserver-xorg-video-intel (2:2.99.917+git20161206-1)
xserver-xorg-video-nouveau (1:1.0.13-1+b1)
xserver-xorg-video-qxl (0.1.4+20161126git4d7160c-1)
xserver-xorg-video-radeon (1:7.8.0-1+b1)
xserver-xorg-video-vesa (1:2.3.4-1+b2)
xserver-xorg-video-vmware (1:13.2.1-1+b1)最后添加了其余的软件包:
Installed the following packages:
ubuntu-desktop (1.361)
xserver-xorg-input-evdev (1:2.10.5-1)有两个包被删除了,我无法用Debian版本替代它们:xserver-xorg-input-vmmouse和xserver-xorg-input-wacom。但我个人并不需要它们,因为我的笔记本电脑不是Wacom平板电脑,我也不打算使用VMWare (我更喜欢VirtualBox )。
我希望这能帮到别人
编辑:当然,这是不言而喻的,在这样做之后禁用Debian存储库.我用继承人的回复来修复错误,而不是在我的日常生活中。如果我想有希德十年前给我的头痛,我会安装Debian .
