Synaptics 触摸板滚动不起作用

Synaptics 触摸板滚动不起作用

我在 Dell Studio 1557 上运行 Ubuntu 14.04。我的 Synaptics 触摸板被检测到,但滚动功能不起作用。GUI 中鼠标和触摸板的滚动选项已消失。我尝试重新安装 xserver-xorg-input-synaptics 包,但收到以下错误:包“xorg-input-abi-20”没有安装候选项。请提供解决方案。

以下是输出,我仍然无法安装多点触控包。

答案1

这可能是一个错误,因为在 14.04 中这些选项可通过 GUI 获得。

这是一个可行的解决方案,请在此处查看原始答案启用边缘和双指滚动

使用 gedit 或文档编写器创建脚本非常简单

首先打开gedit并复制并粘贴以下内容:

#!/bin/bash

synclient VertEdgeScroll=1
synclient VertTwoFingerScroll=1

将文件保存为scrolling.sh您的~/bin目录中

更改权限以便能够将其作为程序运行打开终端CTRL + ALT + T运行此命令:

chmod +x ~/bin/scrolling

在 Dash 中搜索Startup Applications,然后打开它然后设置滚动在 ubuntu 启动时运行。

在此处输入图片描述

答案2

尝试安装 gpointing-device-settings,它在我的华硕上运行良好。

sudo apt-get update
sudo apt-get install gpointing-device-settings

它从 GUI 界面运行,您会在应用程序中找到它,只需搜索指点设备,图标只是一个鼠标,但应用程序是用于触摸板的。有一个单独的滚动选项卡。

或者,从命令行

gpointing-device-settings

实际上我的系统响应更快。

修复损坏的包裹。

尝试代码:

sudo apt-get update

更新你的软件包列表。然后代码:

sudo apt-get autoclean

清理任何不完整的包。然后代码:

sudo apt-get clean

清理 apt 缓存。代码:

sudo apt-get autoremove

将清除所有不需要的依赖项。如果在执行此操作时您可以识别损坏的包,此代码将非常强制地将其删除。代码:

sudo dpkg --remove -force --force-remove-reinstreq <package name>

当然是将包名称更改为真实名称。

然后

代码:

sudo apt-get install -f 
sudo dpkg --configure -a

最后一步是确保没有剩余的破损包裹。

您现在就可以安装您的软件包了。

要完全删除 xserver-xorg 并重新安装,请执行以下操作。

使用以下命令删除现有的 xorg

sudo apt-get remove --purge xserver-xorg

使用以下命令安装 xorg

sudo apt-get install xserver-xorg

使用以下命令重新配置 xorg

sudo dpkg-reconfigure xserver-xorg

然后尝试再次安装多点触控。

答案3

我刚刚进入系统设置,在鼠标和触控板选项下选择了“自然滚动”。虽然触控板对侧面和底部的滑块没有反应,但当我将两根手指放在上面时,它确实可以正确滚动。

答案4

我的富士通笔记本电脑也遇到了同样的问题。最后我通过替换一些代码解决了这个问题

/etc/default/grub

这是我修改后的文件的样子。

GRUB_DEFAULT=0       
GRUB_HIDDEN_TIMEOUT=0    
GRUB_HIDDEN_TIMEOUT_QUIET=true       
GRUB_TIMEOUT=10    
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo debian
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"       
GRUB_CMDLINE_LINUX=""   
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i8042.notimeout i8042.nomux"

然后运行命令

sudo update grub

也许它会对你有帮助。
