![nvidia-settings 未检测到显示](https://linux22.com/image/856634/nvidia-settings%20%E6%9C%AA%E6%A3%80%E6%B5%8B%E5%88%B0%E6%98%BE%E7%A4%BA.png)
我有 ubuntu 14.04 和 nvidia 驱动程序 331.38。我的笔记本有 GeForce GT 555M 和 Intel 显卡。ubuntu 运行正常,除了一个问题。我想连接两个外接显示器,但发现 nvidia-settings 甚至检测不到笔记本内置显示器。如果我连接 HDMI 和 VGA,nvidia-settings 只会显示 VGA 显示器。
如果没有连接外部显示器,则 nvidia-xconfig 的输出为:
nvidia-xconfig --query-gpu-info
