![X 睡眠后崩溃,配备英特尔模式设置驱动程序的戴尔 7490 笔记本电脑,xrandr 也很奇怪,Ubuntu 18.10](https://linux22.com/image/1011470/X%20%E7%9D%A1%E7%9C%A0%E5%90%8E%E5%B4%A9%E6%BA%83%EF%BC%8C%E9%85%8D%E5%A4%87%E8%8B%B1%E7%89%B9%E5%B0%94%E6%A8%A1%E5%BC%8F%E8%AE%BE%E7%BD%AE%E9%A9%B1%E5%8A%A8%E7%A8%8B%E5%BA%8F%E7%9A%84%E6%88%B4%E5%B0%94%207490%20%E7%AC%94%E8%AE%B0%E6%9C%AC%E7%94%B5%E8%84%91%EF%BC%8Cxrandr%20%E4%B9%9F%E5%BE%88%E5%A5%87%E6%80%AA%EF%BC%8CUbuntu%2018.10.png)
首先,我在尝试使用 xrandr 设置外部显示器时遇到了各种问题,这些显示器已成功配置,然后断开连接并重新连接,可能是在笔记本电脑处于睡眠状态之后。在这些情况下,每次尝试使用 xrandr,甚至--auto
都会导致xrandr: Configure crtc 1 failed
。我提到这一点是因为我怀疑它与更大的问题有关……
后来我让笔记本电脑进入睡眠状态,然后将其唤醒,结果屏幕一片漆黑。我按下 ctrl+alt+f5,虚拟终端工作正常,然后我按下 ctrl+alt+f2 返回默认 GUI,结果在左上角只看到一个白色下划线光标。ctrl+alt+f1 将我带到备用 GUI,它启动正常,并显示 GUI 登录提示。ctrl+alt+f2 将我带到一个我没想到的文本 tty2。
以下是我认为的一些关键日志条目:
dmesg:

我不知道如何从这里继续进行进一步的故障排除。
