从 16.04 升级到 18.04 会中断 i915 驱动程序检测

  • 772

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。

$ sudo lsmod | grep i915

i915                 1937408  0
i2c_algo_bit           16384  1 i915

video                  49152  1 i915

$ lshw -c video

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：

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

我该如何分解这个问题？

i915 gpu-driver intel-nuc 18.04

1 个回答

  1. Best Answer

    i915.alpha_support=1从禁用/etc/default/grub，update-grub然后重新启动启用驱动程序。

    感谢没有人提供解决方案。

    然而，我还没有找到知道它为什么起作用的方法。
