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:
