我最近从 16.04 升级到了 18.04,并且遇到了严重的系统冻结问题,并且想知道如何最好地诊断这些问题。
以下是发生的事情:
- 系统完全冻结 - 显示仍然存在,但没有鼠标或键盘响应
- ctrl-alt-del、ctrl-alt-backspace 无响应
- 对 magic sysrq 键没有响应(atl-sysrq-reisub - 已在 /etc/sysctl.d/10-magic-sysrq.conf 中将其设置为 1 来启用
- 事件发生后检查 /var/log/syslog 没有发现任何相关信息。有时崩溃时会出现一系列空字节。kern.log 也有类似的空字节
- 似乎与显示变化/故障有关,例如对接/断开、插入/拔出 HDMI,
- 屏幕略微移动/包裹,就像插入新显示器并进行检测后有时会暂时发生的情况一样。
机器详细信息:
- 联想 x260:
- 英特尔(R) 酷睿(TM) i7-6500U CPU @ 2.50GHz
- 英特尔公司 HD Graphics 520(修订版 07)
- Bios 升级:版本:R02ET64W (1.37),发布日期:2018 年 2 月 26 日
以下是我迄今为止尝试过的方法:
- 执行了 2 次所有扩展 BIOS 硬件自检(每次约 8 小时),均通过
- 尝试按照说明从 ppa:oibaf/graphics-drivers 安装最新的驱动程序这里。
请注意,我在 16.04 下遇到了一些系统挂起,我将其归因于安装有点过时,但我没有进行除对 syslog 进行随意检查(未显示任何内容)之外的调查,因此尽管 BIOS 自我检查通过,但我并没有接近可能存在硬件问题的事实。
问题:
- 对于可能的原因/解决方法有什么建议吗?
- 我应该查看其他日志源来了解发生了什么吗?
- X11 日志保存在哪里?/var/log/Xorg.log 或类似目录中没有任何内容。(答案:~/.local/share/xorg/Xorg.0.log)
- 我可以/应该启用任何其他日志功能吗?
lspci 输出以防有帮助:

编辑 2:又发生了。下面是发生后屏幕的照片。以下是导致此事件的原因:
- 笔记本电脑已对接,但显示屏空白
- 我断开了笔记本电脑的对接(从这个状态 - 没有用鼠标/键盘输入取消屏幕空白)
- 大约 15 秒后,我解锁了屏幕并做了一些事情,包括打开了一个新的网络浏览器窗口
- 大约 30 秒后,冻结发生了
注意 - 黑色到白色的区域已添加到编辑屏幕,并且不是人工制品。

答案1
就我的情况来说,解决办法是删除 acpi-call-dkms包装和在 BIOS 中将显卡内存增加到 512MB(Ubuntu 18.04、联想 X250、两个显示器(通过 DP)+一个显示器(通过 VGA)。如果没有外接显示器,即使使用 acpi-call-dkms,笔记本电脑也不会死机。
acpi_call 抱怨:
acpi_call:模块验证失败:缺少签名和/或所需密钥 -污染内核
