我使用的是 Debian Sid，内核 5.19.0-1-amd64。我的机器是 ThinkPad T14 Gen 3，带有集成图形控制器和 NVIDIA GPU；这是结果lshw -c display：

我正在尝试让硬件加速发挥作用（主要是在 Chrome 中，以便 Google Meet 和 Zoom Web 顺利运行）。问题似乎是 VA-API（版本 1.15.0）似乎没有连接到任何一张卡，无论我使用什么环境参数。

无论我安装 Intel 硬件的免费驱动程序（软件包intel-media-va-driver）还是非免费驱动程序（intel-media-va-driver-non-free），问题都是一样的。对于 NVIDIA 驱动程序，我尝试安装推荐的软件包nvidia-detect（很简单nvidia-driver）以及另一个建议的软件包（nvidia-testla-470-driver），两者都以相同的方式失败。我还尝试将 Xorg 配置修改为仅使用 NVIDIA GPU，但这并没有改变任何事情。
我不知道它是否相关，但intel_gpu_top似乎也失败并出现一条模糊的错误消息：
root@cyclone:/# intel_gpu_top
intel_gpu_top: ../tools/intel_gpu_top.c:1910: init_engine_classes: Assertion `max >= 0' failed.
Aborted
我的下一步应该是什么？
