嗨，我有HP ProBook 450 G3安装了 ubuntu 16.04 LTS。
不幸的是，它总是随机冻结。这似乎是显卡的问题，因为冻结前屏幕经常会发生一些奇怪的事情（颜色/形状发生变化）。
是否有任何额外的软件可以安装或执行一些检查，从而提供有关失败原因的更多详细信息？

嗯，出于好奇，我已将 Linux 降低到 15.10，但问题仍然存在。在系统日志中，我看到类似以下内容：

答案1
您应该阅读 certification.ubuntu.com 以找到最适合您笔记本电脑的 ubuntu 版本。对于您来说，我认为您应该为 HP probook 450 安装 ubuntu 14.04 LTS（我的笔记本电脑是 probook 450 G2）
祝你好运！
答案2
好的，在检查了几个 Ubuntu 版本之后，我用 Windows 10 进行了检查。
结果是一样的，系统无法预测故障。
看来硬件坏了。我需要把它退还给卖家。
