Ubuntu 17.10冻结

Question

我刚刚从Ubuntu17.04更新到17.10，但我遇到了一些烦人的问题。有时系统会冻结并注销我。有人也有同样的问题吗？我该怎么解决呢？

在syslog中，我发现：

为了补充一下对syslog的分析，我发现有很多这样的日志：

gnome-shell[5023]: clutter_layout_manager_get_child_meta: assertion 'CLUTTER_IS_LAYOUT_MANAGER (manager)' failed
gnome-shell[5023]: g_object_set: assertion 'G_IS_OBJECT (object)' failed 

通过搜索，我发现了一个可能与其相关的问题：https://bugzilla.redhat.com/show_bug.cgi?id=1497866

Answer 1

我找到了解决方案:返回使用统一！每次屏幕锁定时，用户会话都会崩溃.像这样工作已经不可能了。我希望新的18.04能解决这个问题。
