昨天还在DOTA2，现在运行了看不到界面！！！！只看到CPU上去很高，怎么办？是你们的问题还是STEAM问题
不清楚，毕竟还是测试版本，有问题是难免的
有人帮帮忙不？？？？？？？我没游戏玩了

是steam的问题，很多人都启动不了steam。上面地址中给出了临时解决方法。
I was having the same problem. To solve it, just delete the .steam/steam/appcache directory. You can do this from the terminal:
rm -Rf ~/.steam/steam/appcache
You have to run this every time you want to start steam until Valve fix this problem.
把方法直接贴过来了
每次都要删除，真……
谢谢啦～～～
