从 16.04 升级到 18.04 会破坏 i915 驱动程序检测

我最近从赛尼尔（16.04.3 LTS） 到仿生的（18.04.3 LTS），并且我的英特尔显卡驱动程序不再被检测到。

i915_bpo我记得我曾经使用过驱动程序。现在模块被检测到了，但无法与显卡关联。

$ sudo lsmod | grep i915

那么，模块在那里，卡在那里，但是卡不想使用模块？浏览了一段时间的现有问题后，我安装了sudo apt install linux-generic-hwe-18.04，因此安装了内核版本。它与没有任何变化4.15.0-91。

因此，Xorg.0.log显示有关此事的以下信息：

此外：

$ dmesg | grep i915

[   68.810865] snd_hda_codec_hdmi hdaudioC0D2: No i915 binding for Intel HDMI/DP codec

/etc/默认/grub：

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i915.alpha_support=1 ..."

我该如何分解这个问题？

答案1

i915.alpha_support=1从禁用/etc/default/grub，update-grub然后重新启动即可启用该驱动程序。

谢谢没有人寻求解决方案。

然而，我还没有找到了解其为何有效的方法。
