如何使用 nvidia-optimus 笔记本电脑玩 Steam 游戏？

Question

在安装了 Ubuntu 12.04 和最新版本的大黄蜂的 NVIDIA Optimus 笔记本电脑上启动 Steam 游戏的最佳方式是什么？

如果我调用 Steamoptirun steam并选择我想玩的游戏，我会收到以下错误：

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.)

如果我在steam没有optirun选项的情况下运行，我可以进一步运行游戏，在黑屏上听到开始音乐，但在此过程中稍后仍然失败。

我应该使用特殊optirun命令而不是调用我想玩的游戏optirun steam吗？

Answer 1

检查这些链接 - 您需要更改游戏属性，如下所示

• 右键单击库中的 TF2
• 单击属性
• 单击设置启动选项
• 如果您只有 optirun，请输入： optirun %command%

以上对我不起作用，我不得不将启动选项设置为

LD_PRELOAD="libpthread.so.0 libGL.so.1" __GL_THREADED_OPTIMIZATIONS=1 optirun %command% 

检查这些讨论：

• http://steamcommunity.com/groups/LinuxOptimus/discussions/1/864951657810665792/

如果这不起作用，请下载hl2-optirun.sh以下位置并运行它。

/home/user/Steam/SteamApps/'account_name'/Team Fortress 2/

Valve 建议使用 primusrun 在 NVIDIA GPU 上运行 Steam 游戏。
