12.04 是否在发布中途添加了多点触控手势支持？

我查看了今天要下载的更新，然后我

  1. 注意到很多问题都与手势支持有关，

  2. 注意到其中许多是新安装而不是升级。

12.04 是否在发布中期添加了多点触摸手势支持？如果是，那么添加了哪些功能？哪些应用程序已经支持这些功能？我是否可以期待其他应用程序在不久的将来添加支持？

以下是已安装的软件包：

Install: libframe6:amd64 (2.2.4-0ubuntu0.12.04.1), libgeis1:amd64 (2.2.9.2-0ubuntu1), libgrail5:amd64 (3.0.6-0ubuntu0.12.04.01, automatic)

以下是已升级的产品（其中还包括许多支持触摸的产品）：

Upgrade: libgrip0:amd64 (0.3.4-0ubuntu2~ubuntu12.04.1, 0.3.5-0ubuntu1~12.04.1), eog:amd64 (3.4.2-0ubuntu1, 3.4.2-0ubuntu1.1), ginn:amd64 (0.2.4-0ubuntu1, 0.2.4.1-0ubuntu1)

其中新安装的描述如下：

libgeis1：

Gesture engine interface support
 A common API for clients of a systemwide gesture recognition and propagation
 engine.

libframe6：

Touch Frame Library
 This library handles the buildup and synchronization of a set of simultaneous
 touches. The library is input agnostic, with bindings for mtdev, frame and
 XI2.1.

libgrail5：

Gesture Recognition And Instantiation Library
 This library consists of an interface and tools for handling gesture
 recognition and gesture instantiation. Applications can use the grail callbacks
 to receive gesture primitives and raw input events from the underlying kernel
 device.

升级包的描述如下：

ligrip0：

provides multitouch gestures to GTK+ apps

 Libgrip hooks gesture recognition into GTK+ applications.

ginn：

Gesture Injector: No-GEIS, No-Toolkits

 A daemon with jinn-like wish-granting capabilities: it gives applications the
 ability to support a subset of multi-touch gestures without having to integrate
 GEIS or multi-touch GTK/Qt libs.

添加大量新库并升级现有组件让我怀疑 12.04 是否会在不久的将来开始原生支持除双指滚动之外的手势。我预计这些功能很快就会推出，但我认为它们只会在新版本中推出，而不是作为现有版本的升级。

有人有关于此事的信息吗？

答案1

我自己也觉得这有点奇怪。我做了一些调查，发现上游项目似乎被重新命名了。

  • 乌托格
  • utouch 框架
  • utouch-grail

现在：

  • 盖斯
  • 框架
  • 圣杯

此更新反映了重命名以及一些错误修复：
