看起来显示器无法显示任何内容，因为 Ctrl + Alt + F* 不起作用。显示器本身可以工作 - 在加载操作系统之前，我看到了几个正确的屏幕。我可以通过 ssh 连接。
我的 gpu 是 GeForce 6600GT。
Debian 9 i386 包含所有更新。

我希望能够修复这个nouveau由于温度较高而导致不使用的问题（没有专有驱动程序）。
答案1
我对该驱动程序的更新版本不太熟悉nvidia，但如果没有其他人想要：
从日志中可以看出，NVIDIA 驱动程序检测到 CRT-0 上的 VGA 模拟显示器，并获取了 EDID 数据（即显示器支持的分辨率和频率）。但是，它没有像其他 X 驱动程序一样列出可用的模式（尽管这可能只是当前 NVIDIA 驱动程序的一个怪癖），而是选择了一种“自动选择”模式。因此，驱动程序似乎很满意，但可能由于某种原因，所选模式是 VGA 显示器不喜欢的。
可以尝试的事情：
1）更换
Driver "nvidia"
和
Driver "nouveau"
在 xorg.conf 中（仅用于测试）。重新启动显示管理器或重新启动。查看Xorg.log，nouveau驱动程序至少应该告诉我们有关 EDID 数据的更多详细信息，以及哪些模式行可用。
2) 卸载nouveau，将xorg.conf文件移开（例如移到您的主目录中），重新启动显示管理器或重新启动。当不xorg.conf存在时，其他 X 驱动程序会采用合理的默认值，希望NVIDIA驱动程序也是如此。再次查看Xorg.log是否出现有效的模式行。
3）如果这没有帮助，并且如果nouveau日志显示了模式行，请添加一些标准模式行（例如 800x600）xorg.log（并切换回驱动NVIDIA程序），看看是否NVIDIA可以说服驱动程序尝试这些模式行。
4) 如果您的显示器具有通过按下显示器上的按钮显示当前水平和垂直频率的功能，则此信息将会很有用。
答案2
我最终apt purge nvidia*删除/etc/X11/xorg.conf并重新安装了nouveau- 现在我又能看到桌面了。为了应对更高的温度，我启用了后置噪音风扇。
