我有一台联想 Thinkpad w540，正在运行 Mint 16。当我将笔记本电脑插入扩展坞时，一切都冻结了。我必须断开连接并等待，直到登录窗口加载完成。我应该如何找出问题所在？
到目前为止我发现了以下内容。我xrandr在对接之前和之后运行了命令，发现存在差异。这是否导致了我的问题？没有对接并将外接显示器直接连接到笔记本电脑：
$ xrandr

连接底座后，外接显示器通过底座连接：
$ xrandr

VIRTUAL1 disconnected (normal left inverted right x axis y axis)
如果我尝试运行此命令：
xrandr --auto --output DP2 --mode 1920x1200 && xrandr --auto --output eDP1 --mode 1920x1080 --left-of DP2
屏幕再次冻结，我不得不关闭笔记本电脑。有什么建议吗？
答案1
回答问题然后删除答案的用户实际上是对的。
已将我的 mint 升级至17，现在冻结问题已消失。
