解决anaconda启动的错误

安装好的anaconda启动报错如下：

anaconda-navigator 
2021-12-02 20:57:12,833 - WARNING linux_scaling.get_scaling_factor_using_dbus:31
An exception occurred during fetching list of system display settings.

QXcbConnection: XCB error: 3 (BadWindow), sequence: 3225, resource id: 14878253, major code: 40 (TranslateCoords), minor code: 0

后来发现是系统下的/usr/lib/libstdc++.so.6.0.29, anaconda下的/lib/libstdc++.so.6.0.28两个版本居然不一致，那就采用偷天换日的方法吧。

mv ~/anaconda3/lib/libstdc++.so.6.0.28 ~/anaconda3/lib/libstdc++.so.6.0.28bake

cp /usr/lib/libstdc++.so.6.0.29  ~/anaconda3/lib/libstdc++.so.6.0.28

现在启动就没有什么问题了：

anaconda-navigator 
2021-12-02 21:34:56,159 - WARNING linux_scaling.get_scaling_factor_using_dbus:31
An exception occurred during fetching list of system display settings.

差不多算是正常了吧
