我正拼命尝试在 Debian Wheezy 上设置我的系统，配备 NVIDIA Quadro 600 显卡和两台显示器（两台显示器完全相同，制造商、尺寸和型号相同）. 一台显示器通过HDMI另一个是显卡电缆。虽然 HDMI 显示器在 1920x1080 分辨率下工作良好，但 VGA 显示器却出现故障。到目前为止，我所做的是：
我已按照 nvidia 驱动程序安装Debian 网站，并安装 nvidia-glx 和所需的内核（DKMS 和 Linux 标头）。
xrandr也无法将 1920x1080 添加--addmode到我想要的输出（VGA 显示器）。nvidia-settings也不包括我想要的 VGA 显示器分辨率。我曾尝试手动将 1920x1080 添加到 xorg.conf，虽然通过添加一些较新的分辨率（例如 1024x768）可以改善情况，但并未添加我想要的 1920x1080。
/etc/X11/xorg.conf如果有帮助的话，这是我的文件：
