我最近从xenial ( 16.04.3 LTS) 升级到bionic ( 18.04.3 LTS)，并且不再检测到我的 intel 显卡驱动程序。
据我所知，我曾经用作i915_bpo驱动程序。现在模块被检测到，但没有与显卡相关联。

那么，模块有，卡有，但卡不想用模块？在浏览了现有问题一段时间后，我已经安装了sudo apt install linux-generic-hwe-18.04，因此是内核版本。它没有改变任何东西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

/etc/default/grub：

我该如何分解这个问题？
