在安装了Ubuntu 12.04和最新版本的bumblebee的NVIDIA Optimus笔记本电脑上启动Steam游戏的最佳方法是什么？
如果我致电Steam，optirun steam然后选择我要玩的游戏，则会收到以下错误：
The program 'hl2_linux' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadDrawable (invalid Pixmap or Window parameter)'.
(Details: serial 125 error_code 9 request_code 14 minor_code 0)
(Note to programmers: normally, X errors are reported asynchronously;
that is, you will receive the error a while after causing it.
To debug your program, run it with the --sync command line
option to change this behavior. You can then get a meaningful
backtrace from your debugger if you break on the gdk_x_error() function.)

如果steam没有optirun选项，我可以进一步运行游戏，在黑屏上听到开始的音乐，但稍后仍会失败。
我应该使用特殊optirun命令而不是我想玩的游戏optirun steam吗？
primusrun steam工作很棒。
