![Ubuntu 16.04.5 LTS - 从暂停状态恢复时出现黑屏/无响应](https://linux22.com/image/1010605/Ubuntu%2016.04.5%20LTS%20-%20%E4%BB%8E%E6%9A%82%E5%81%9C%E7%8A%B6%E6%80%81%E6%81%A2%E5%A4%8D%E6%97%B6%E5%87%BA%E7%8E%B0%E9%BB%91%E5%B1%8F%2F%E6%97%A0%E5%93%8D%E5%BA%94.png)
我是 Ubuntu 新手。几个月前将它添加到我的 Dell Latitude 中。一直运行良好,直到最近(大约 2 周),它开始在从暂停状态恢复时崩溃。
步骤如下:1. 通过点击暂停或关闭盖子将 Ubuntu 置于暂停状态 2. 暂停后重新启动 - 显示空白屏幕 - 完全没有响应。没有读取硬盘,但我能听到风扇转动的声音。3. 我必须硬重启。有时当它再次恢复时,它会在显示驱动程序上抛出错误或无法连接到 wifi。我必须再次重新启动它才能使其正常工作。
当我查看 /var/log/kern.log 时,我看到了异常多的条目。由于我是 Ubuntu 新手,自己无法弄清楚很多问题。
以下是我注意到的一些问题。希望得到帮助:
