检查龙芯GPU驱动是否正常安装

请根据步骤1所提供的驱动安装方法进行安装，如整个安装过程没有提示任何错误，且顺利完成整个安装过程，即龙芯GPU驱动已顺利完成安装。

请注意：安装完后需要重启才能正常的使能显卡加速功能。

针对龙芯LG100/LG200系列显卡，请检查2D和3D是否使用了龙芯GPU驱动进行加速

查看X日志文件

查看/var/log/Xorg.0.log可以看到有多个“loonggpu”关键字样且没有EE错误表示2D驱动正常。如下：

运行glxinfo

查看OpenGL renderer string字段发现有LoongGPU字样，代表3D加速正常，如下：

OpenGL renderer string: LoongGPU(TM)
