Linux中启动Steam报错libGL error的解决办法

安装好Steam之后，点击启动器一直没有反应，所以去终端用命令steam启动Steam查看日志，发现终端输出如下内容，然后一直卡着，使用Ctrl C结束进程。

~ $ steam
Running Steam on ubuntu 16.04 64-bit
STEAM_RUNTIME is enabled automatically
Installing breakpad exception handler for appid(steam)/version(0)
libGL error: unable to load driver: r600_dri.so
libGL error: driver pointer missing
libGL error: failed to load driver: r600
libGL error: unable to load driver: swrast_dri.so
libGL error: failed to load driver: swrast
^C

在网上查了一下解决办法，要执行下面的命令：

$ find ~/.steam/root/ \( -name "libgcc_s.so*" -o -name "libstdc++.so*" -o -name "libxcb.so*" \) -print -delete

执行后终端输出如下内容：

/home/ricky/.steam/root/ubuntu12_32/steam-runtime/i386/lib/i386-linux-gnu/libgcc_s.so.1
/home/ricky/.steam/root/ubuntu12_32/steam-runtime/i386/usr/lib/i386-linux-gnu/libstdc++.so.6
/home/ricky/.steam/root/ubuntu12_32/steam-runtime/i386/usr/lib/i386-linux-gnu/libstdc++.so.6.0.21

再次使用命令steam启动Steam，保持网络正常，终端会输出很多内容，最后在Installing ...那段会卡住几分钟，同时桌面会出现Steam更新界面，如下所示，中间有很长一段内容用...表示了：

省略。。。。。

如果长时间没响应，Ctrl C结束进程

等待几分钟后应该会出现Steam登录界面。
上述的方法没有经过反复测试，而且每个人系统会有差异，所以可靠性不能保证，仅供参考。
