我有 Radeon RX 550 显卡华擎 Z370 PRO4 主板，带有板载英特尔显卡和 Linux Mint 18.2，我试图让专用显卡和板载显卡同时工作。
我已启用IGPU多显示器在BIOS中。
操作系统检测到集成显卡，但显示为无人认领，我在 HDMI 端口上没有收到任何信号，并且Display程序未检测到连接的显示器。

我还能做什么来启用板载显卡？
答案1
我设法使设置正常工作，因此我将其发布在这里，以防有人遇到类似的问题。
首先 - 为了从卡中获得任何反应，我需要i915.alpha_support=1在 GRUB_CMDLINE_LINUX_DEFAULT 中设置选项。之后，板载卡现在工作正常，但至少它显示了一些东西，通过 HDMI 的声音工作正常，并且它显示在Display实用程序中。
接下来我发现在更新的内核中不需要 alpha_support 标志 - 所以更新后4.15我遇到了相同的情况，但不需要额外的启动选项。
然后我找到了一些建议摆脱xserver-xorg-video-intel司机。之后两个显卡都可以正常工作。
