我正在尝试用旧零件组装一台 htpc，一切似乎都很好，但我想使用专用卡，以免在输出视频时耗尽所有板载 RAM。我的主板是华硕 M2A-VM，显卡是 XFX nVidia 8500GT 1GB。计算机正常启动，图形从板载视频中输出，但当我插入视频卡并将 BIOS 优先级设置为 PCIEx 时，没有视频输出，板载仍然有效。卡在旋转，我将其插入另一台计算机，它工作正常。不知道还能做些什么来排除故障。
操作系统 Xubuntu 13.10

答案1
这不是一个真正合适的解决方案，但它对我来说很有效，希望有人能找到更好的方法来做到这一点。
我安装了 Windows 7，并安装了 nvidia 驱动程序，将显卡连接到主板，将视频切换到显卡，一切正常。启动到 Xubuntu live cd 并安装了除 Windows 7 加载程序之外的所有内容（可能您也可以摆脱它）。现在显卡在 Xubuntu 中工作正常
