Ubuntu 21.10 没有为英特尔 Intel TigerLake Iris Xe Graphics 加载驱动程序

我遇到的问题与描述基本相同这里或者这里或者这里：我的英特尔 GPU 驱动程序未加载。如下所示

$ inxi -G
Graphics:
  Device-1: Intel TigerLake-LP GT2 [Iris Xe Graphics] driver: N/A 
  Device-2: NVIDIA TU117M [GeForce GTX 1650 Ti Mobile] driver: N/A 
  Display: x11 server: X.Org 1.20.13 driver: loaded: fbdev 
  unloaded: modesetting,vesa resolution: 1920x1200~77Hz 
  OpenGL: renderer: llvmpipe (LLVM 12.0.1 256 bits) v: 4.5 Mesa 21.2.2

或此处（显示无人认领的）

$ sudo lshw -c video

在上述三个案例中，问题都通过以下方式解决：

apt install linux-oem-20.04

因为它们都在 Ubunut 20.04 上运行，需要更新的内核。不幸的是，安装 OEM 内核对我来说不起作用。有什么建议，如何解决这个问题？

有关我的系统的更多信息，如果需要更多信息请告诉我:)

答案1

GRUB_CMDLINE_LINUX_DEFAULT=nomodeset我在 grub 文件集中有这个选项。这阻止了英特尔驱动程序的加载。因此，删除它nomodeset解决了这个问题。解决方案的想法来自这邮政。
