我最近安装了OBS工作室在我的笔记本电脑（联想 Thinkpad T410）上安装 Ubuntu 20.04 LTS。虽然我在安装过程中没有遇到任何问题，但我无法运行 OBS Studio 本身，因为我一直遇到以下错误：
Failed to initialize video. Your GPU may not be supported, or your graphics drivers may need to be updated.
为了向您提供所有必要的详细信息，这里是该obs命令的完整控制台输出：

搜索问题后，我发现我的问题在于我的 OpenGL 版本太旧了（2.1）。虽然我的 GPU（集成；我的 CPU 是 Intel i5 M520）不是最先进的，但它对于 OBS Studio 来说似乎并不太旧，因为我也在 Windows 10 上安装了相同的程序（因为我的笔记本电脑是双重启动) 并且我运行它从我的网络摄像头或打开的窗口中捕获数据没有任何问题。
但是，我很难找到如何在 Ubuntu 20.04 下升级我的 OpenGL 版本。我最好的尝试是通过 PPA 获取更新版本的 Mesa 3D 库kisak-mesa，但虽然它升级了我的 Mesa 版本，但并没有改变 OpenGL 版本。这是我运行命令时得到的结果glxinfo | grep "OpenGL version"：
OpenGL version string: 2.1 Mesa 20.2.1 - kisak-mesa PPA
另外，我还看了附加驱动程序选项卡软件和更新，但就我而言，此选项卡完全是空的，并且没有建议任何可以改善我当前情况的驱动程序。
我能做什么来解决这个问题？最近的另一个问题建议通过 snap 安装 OBS Studio，但尽管尝试了，我仍然遇到与之前相同的问题。
在此先非常感谢您的帮助。
