Synaptics 触摸板滚动不起作用

Question

我在 Dell Studio 1557 上运行 Ubuntu 14.04。检测到我的突触触摸板，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。我曾尝试重新安装 xserver-xorg-input-synaptics 包，但收到以下错误包“xorg-input-abi-20”没有安装候选。请建议解决方案。

以下是输出，我仍然无法安装多点触控包。

Answer 1

尝试安装 gpointing-device-settings，它在我的华硕上有效。

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，但该应用程序适用于触摸板。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速度更快。

修复损坏的包。

尝试代码：

sudo apt-get update

更新您的包裹清单。然后代码：

sudo apt-get autoclean

清理任何部分包。然后代码：

sudo apt-get clean

清理 apt 缓存。代码：

sudo apt-get autoremove

将清除任何不需要的依赖项。如果在执行此操作时您可以识别损坏的包，则此代码将非常有力地将其删除。代码：

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

当然将包名更改为真实名称。

然后

代码：

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

最后一步是确保您没有剩余的破损包裹。

您现在应该可以安装软件包了。

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

然后再次尝试安装多点触控。

Answer 2

尝试禁用两指滚动。我的在那之后工作得很好，因为新的 14.04 已准备好启用该功能的现代 Synaptic 触摸板。
