如何获取 Alder Lake 显卡驱动程序?我正在运行带有 HWE-edge 内核 (5.13) 的 20.04,但无法使用 igpu 进行硬件加速。
$ sudo lshw -c display
*-display UNCLAIMED
description: VGA compatible controller
product: Intel Corporation
vendor: Intel Corporation
physical id: 2
bus info: pci@0000:00:02.0
version: 0c
width: 64 bits
clock: 33MHz
capabilities: pciexpress msi pm vga_controller bus_master cap_list
configuration: latency=0

对于其他不受支持的新硬件(例如 2.5GBE),我能够从制造商的网站下载驱动程序。英特尔没有类似的产品吗?
答案1
最终,HWE-edge 内核更新至 5.15 并包含英特尔驱动程序。您可以看到现在 i915 驱动程序显示为sudo lshw -c display
。
