Ubuntu 16.04引导在冻结和工作之间交替

目前，当尝试启动到Ubuntu 16.04时，它会交替冻结或正常工作。

在它冻结的场合，它进入“请解锁磁盘sda5_crypt2屏幕。按CTRL + ALT + F1 – F6将我带到一个闪烁的提示，如果我输入没有任何反应。

如果我按下CTRL + ALT + F7，我可以输入屏幕上显示的内容并按回车键（我转到新线路上），但没有任何反应。

如果我重新启动机器，它将启动到Ubuntu OK，虽然加载屏幕的分辨率很低。

当我安装nVidia Cuda Toolkit 8.0时出现问题，导致我的PC在启动时冻结。 之后，我不得不使用启动选项启动到恢复模式和控制台，使用这些命令来修复它：

apt-get purge fglrx -y rm /etc/X11/xorg.conf 

每次尝试成功启动，我该怎么办？

在/var/log/syslog有什么我应该寻找的吗？

我的系统是配备Quadro 4000的Dell Precision 7500。

编辑：从/ var / log / syslog中添加内容…

我尝试在无法启动时以及无法启动时捕获syslog。 它似乎没有进入它无法启动时创建日志文件的阶段。 它冻结的屏幕是“请解锁磁盘sda5_crypt2”屏幕。

它在启动时的日志头部位于下方（由于30k字符限制，我无法粘贴完整的日志）。 是否有任何线索知道它在之前的尝试中失败了？
