我上周玩了一款 Steam 游戏，没有问题。然后我从 Ubuntu Mate 15.04 升级到 15.10，然后出现了错误。
下面是日志文件。大部分内容对我来说都像是乱码，但 mono 似乎造成了致命问题。有人知道该怎么处理吗？我可以将 mono 降级回以前的版本吗？我不确定该怎么做，所以任何帮助都非常感谢。

答案1
我已经安装了 ubuntu-desktop，这似乎解决了这个问题。
编辑：要安装 ubuntu-desktop，请打开终端并输入
sudo apt-get install ubuntu-desktop
正如问题中提到的，我运行的是 MATE（据我所知是 gnome2 变体），而不是 ubuntu-desktop 包中的 Unity。
