我有 Windows 11 和 Ubuntu 22.10 的双启动系统。笔记本电脑基于英特尔 Alder Lake 平台，配备 i5 1230u 处理器。内部 WebCamera (HI847) 传感器在 Ubuntu 中不起作用，但在 Windows 中起作用。我尝试了一些 Linux 内核（从 6.0 到 6.1.9），但没有帮助。所以我遵循了本指南https://github.com/intel/ipu6-drivers并安装了所有必要的驱动程序。此 repos 不包含 hi847 传感器驱动程序，但 Linux 内核包含。文件 /dev/video0 存在，但 cheese 和 guvcview 无法识别它（错误如“/dev/video0”不存在）。webcamtest.com 也向我展示了此结果（discord 相同）。
命令dmesg | grep intel包含有关英特尔驱动程序的以下行：
