Ubuntu 11.04在使用中间随机注销
我可以看到已经有一个问题了。因为我的问题并不完全相同但据我所知非常相似，我也在问它。
基本上在我的使用中间，即浏览网络或运行随机应用程序。 Ubuntu将我发送到登录窗口，我必须重新登录。 我不知道GDM是否重启或其他什么。 即使在Ubuntu的稳定版本中，这也是我遇到的问题。
有一个我不知道的错误吗？ 我该怎么调试呢？
这是我的~/.xsession_errors文件输出。

我最近得到了gnome-sessions的更新。 我希望能解决这个问题，但是经过几天测试后我才能确定……会更新情况。
更新：没有进展，得到更新，但问题仍然存在。 但它似乎比以前少得多。 我正在跟进这个问题，因为有些人建议我重新安装，但现在我在compiz配置更改后面临Unity冻结
这是一个错误 。
这可能是video驱动程序崩溃。 你的video卡是什么？ 你使用专有驱动程序吗？ 如果是，请尝试其他版本，或尝试完全删除它。 或者，不幸的是，它可能是许多其他硬件。 X服务器是粘土腿上的庞然大物，最容易受到硬件故障的影响。 检查内存（memtest86），HDD（fsck，智能），温度（lm-sensors）。 尝试关闭所有不必要的硬件和软件。 例如，当EiskalDC ++尝试索引100Gb文件时，我曾看到X服务器崩溃。 你读过日志吗，dmesg？ 有什么可疑的吗？ PS关闭compiz。 它默认在ubuntu中启用。
你在使用Unity还是GNOME？ 试试另一个。 如果这不起作用，我会建议尝试Xubuntu（看看它是否是GNOME）。 如果全部失败，请备份您的主分区或文件夹，并将/ var / cache / apt复制到另一个文件夹，然后重新安装。 使用缓存中的Packages重新安装应用程序。
尝试（在终端，没有SUDO）：
unity --reset
然后不要再次触摸CCSM（Compiz设置）。 我不知道这对你的情况是否真的有帮助，但是我处于同样的情况，目前正在测试崩溃是否仍然存在。
