希望大牛们帮我看看是什么问题。

EE) Failed to load /usr/lib64/xorg/modules/drivers/intel_drv.so: libdrm_intel.so.1: cannot open shared object file: No such file or directory

提示要加载 /usr/lib64/xorg/modules/drivers/intel_drv.so文件，但这个文件要依赖 libdrm_intel.so.1谁的。

libdrm_intel.so.1文件没有在系统中找到，可能的原因大概有两种：
1. 包含此文件的软件包未安装
可用emerge -S libdrm_intel.so.1等，或google查查到这个文件是在哪个软件包中。

2. 软件包已经安装，需要设置 LD_LIBRARY_PATH 变量
将此文件放入到类似下面目录下。再执行下ldconfig
LD_LIBRARY_PATH='/lib:/data/local/lib:/usr/local/lib'
