简短问题:
如何知道内核升级是否导致我的硬件停止工作?
较长的版本:
如果我理解正确的话:
- Ubuntu 16.04.1 使用内核版本 4.4
- Ubuntu 16.04.2 使用内核版本 4.8
我有一种预感,由于从内核版本 4.4 升级到 4.8,我的 Gigabyte Brix 上的蓝牙和图形不再正常工作。(需要说明的是,它们在全新安装的 Ubuntu 16.04.1 上运行良好,但在全新安装的 Ubuntu 16.04.2 或完全升级的 16.04.2 上无法正常工作。)
我如何才能知道内核版本 4.4 是否支持某个特定硬件而 4.8 版本不支持?
(如果相关,具体问题是:蓝牙不会发现某些事物,并且会连接,但不会与其他事物协作;图形看这里。
以下是有关硬件的一些详细信息:
