Gnome 3.8（Ubuntu Gnome 13.04）启动后无法启动。 在哪里寻找这种日志？
直到昨天，在gnome3-team ppa上使用GNOME 3.8的Ubuntu GNOME 13.04上一切正常。
今天我再也无法登录了。 启动后，它挂在GDM的蓝色桌面上，没有任何反应。
我刚刚重新安装Ubuntu GNOME保留我的主文件夹，问题仍然存在。 请注意，这次我没有放任何第三方PPA。
从哪里开始寻找这个问题的解决方案？ /var/log/boot.log除了某种“saned”被禁用的问题外，看起来还不错。
我在syslog中发现了一些错误

先感谢您。
我也犯了不使用sudo apt-get dist-upgrade而无法登录的错误。
幸运的是，有一种方法可以在不重新安装Ubuntu的情况下应用完整更新。 重新启动计算机并认为启动过程完成后，请按Ctrl+Alt+F1 。 系统将提示您输入命令行。
使用您的用户名和密码登录，并确保您有互联网连接（例如ping google.com ）。 如果您的WiFi无法正常工作，请使用以太网电缆将计算机连接到路由器。
然后，您只需输入sudo apt-get dist-upgrade ，您的机器就会下载并安装缺少的软件包。 sudo shutdown -r now使用sudo shutdown -r now重新启动计算机，重新启动后，Gnome 3.8应该可以正常工作。
我注意到你提到你已经安装了gnome3 PPA。 您是否确保在安装此PPA时使用以下sudo apt-get dist-upgrade执行更新： sudo apt-get dist-upgrade而不是仅使用upgrade选项？ 这在PPA的发行说明中提到，如果没有这样做，它将导致类似于您描述的症状。
