我的 2 个显卡配置有问题。我有一个内部英特尔（iGPU i7 4xxx）和一个非常旧的 Trident TGUI 9xxx PCI 卡。如果我使用该卡作为主要 kde 启动效果很好，但我需要在多监视器模式下进行配置。我无法使用 Xinerama，因为 XOrg 服务器无法启动。在当前配置下，我的主显示屏正常，第二个显示屏（连接到三叉戟）呈黑色，光标为 X（我可以将光标移动到该显示屏）。如果我启用 Xinerama，则 XOrg 会无限期地循环重启，这似乎是 Xinerama 和 XRandR 的不兼容。
那么如何启用这两个带有两张卡的显示器呢？
xrandr 没有检测到我的第二个屏幕，这是输出：
