java - Eclipse 在 Ubuntu 上卡住 UI

Question

我最近安装了ubuntu 16.04(自动更新到这个版本)，我平时用Java开发，我会eclipse，所以我安装了，没问题。

我配置了所有需要的东西(Java 路径、JDK...没有什么特别的)，除了 Eclipse UI 之外工作正常。

每次我创建一个项目(尽管项目创建正确)，每次我运行任何程序(尽管程序按预期运行(并不总是正确 xD，但那是我的错))，以及与许多其他任务。

知道为什么会发生这种情况吗？更好的是，如何解决？

我还仔细检查了我使用的 JRE(因为我发现人们在使用开源软件时遇到问题)，我使用的是 oracle 的版本(现在不确定名称，抱歉，版本 8)。上面的所有内容都是 64 位版本。

编辑:我忘了说我用的是火星版。另外，我刚刚安装了 NetBeans (8.1)，完全相同的问题，然后我认为是图形驱动程序的问题，重新安装，仍然有同样的问题。不知道现在该尝试什么。

更新:已检查日志文件。我没有看到任何奇怪的东西，但可能遗漏了一些东西:

更新 2: 我只是运行@dan 建议的命令。这是结果

Linux 上的 Eclipse UI 默认使用 GTK 3 来显示内容，但我发现经常会出现问题。我不确定这是否是问题的根源，但您可以通过使用环境变量设置禁用 GTK 3 支持来检查它:export SWT_GTK3=0。但是，在您发现这就是问题的根源之前，我不会永久打开它。
