以下是我之前发布的有关系统设置挂起问题的更多信息（Ubuntu 16.04.2 打开系统设置时挂起）
在过去的六次尝试中，这是第一次没有无限期地挂起。我密切关注时钟，这是系统挂起 11 秒后记录的信息（22:02:46 - 22:02:57）。

答案1
这很可能是由于您的笔记本电脑上的 svideo 造成的。
您可以尝试使用内核启动选项禁用 svideo，如下所示：
video=SVIDEO-1:d
如果你有 grub，你可以编辑该文件/etc/default/grub并更改以下行：
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash video=SVIDEO-1:d"
然后执行：
$ update-grub
$ reboot
答案2
您的视频驱动程序崩溃了。您是否正在运行包含所有更新的最新版本的 Ubuntu？您是否安装了任何特殊的视频驱动程序？
你的 BIOS 很老旧了。请F.5A Rev. A尽快更新到最新版本，网址为https://support.hp.com/us-en/drivers/selfservice/hp-pavilion-dv6700-entertainment-notebook-pc-series/3632100
对于英特尔处理器，您应该intel-microcode安装...以确保您拥有最新的处理器微码...
在terminal...
sudo apt-get update
sudo apt-get install intel-microcode
