目前，当尝试启动到 Ubuntu 16.04 时，它会交替冻结或正常工作。
有时当它冻结时，它会进入“请解锁磁盘 sda5_crypt2 屏幕。按CTRL+ ALT+ F1-F6会带我进入闪烁的提示，如果我输入，什么也不会发生。
如果我按下CTRL+ ALT+，F7我可以输入屏幕上显示的内容并按下回车键（然后我转到新行），但什么也不会发生。
如果我重新启动机器，它将启动到 Ubuntu OK，尽管加载屏幕的分辨率较低。
当我安装 nVidia Cuda Toolkit 8.0 时出现了问题，导致我的电脑在启动时冻结。之后，我不得不使用启动选项来启动到恢复模式和控制台，使用以下命令来修复它：
apt-get purge fglrx -y
rm /etc/X11/xorg.conf
我该怎么做才能每次都成功启动？
我应该寻找什么吗/var/log/syslog？
我的系统是配备 Quadro 4000 的 Dell Precision 7500。
编辑：从 /var/log/syslog 添加内容...
我尝试在启动失败和正常启动时捕获系统日志。它似乎无法在启动失败时创建日志文件。它冻结的屏幕是“请解锁磁盘 sda5_crypt2”屏幕。
启动时日志的开头如下（由于 30k 字符的限制，我无法粘贴完整日志）。是否有任何线索表明它知道上次尝试失败了？
