在我的台式机上，VLC 播放器消耗了 16 线程处理器的近 30%，我怀疑我的 AMD GPU 驱动程序配置不正确。之前我注意到最新的 Radeon 驱动程序 19:50 仅安装在 5.0 内核中，因此我降级了内核版本，然后安装了 GPU 驱动程序。但我仍然遇到问题。
我尝试在 VLC 偏好设置中禁用“硬件加速解码”，并注意到 CPU 消耗与启用时相同。因此我可以确认 GPU 未被使用。
当我尝试从终端加载 vlc 时，它显示未找到驱动程序。我试过任何有关如何进一步解决此问题的帮助？我应该重新安装 GPU 驱动程序吗？

编辑：我安装了 Kodi Player，它使用非常少的 CPU 资源（最多 3%）就可以完美运行。VLC 似乎在识别最近的 AMD Radeon 19:50/Ubuntu 18.04 组合的 OpenGL 驱动程序时存在一些问题。如果有人解决了这个问题，请更新。我会将其标记为答案并修复我的系统。
