我已成功在运行 Ubuntu 12.10 的 ATI 混合图形系统上安装了 ATI Catalyst 驱动程序。我已验证 OpenCL 和 OpenGL 可以独立工作；但是 OpenCL-OpenGL 互操作无法正常运行。我进行了一些调试，但不确定下一步该怎么做。有人能帮忙吗？
细节：
我的系统是 HP Envy 6，运行 Ubuntu 12.10（已应用所有更新），配有由 Radeon 7600m 和 Intel HD3000 组成的 ATI 混合显卡系统。我按照以下说明安装了最新的 ATI Beta 驱动程序（v. 12.11）：
通过这样做，我能够让 OpenGL 和 OpenCL 正常运行。 glxgears以 ~1200 fps 的速度运行，并且 AMD APP SDK 中的所有 OpenCL 专用示例都按预期运行。但是，任何 OpenCL-OpenGL 互操作应用程序都无法启动并出现错误X Error of failed request: BadMatch (invalid parameter attributes)。所有示例代码之前都在 Ubuntu 12.04 下使用包管理器 ATI 驱动程序运行。
为了获取更多调试信息，我运行了LIBGL_DEBUG=verbose /opt/AMDAPP/samples/opencl/bin/x86_64/SimpleGL。这将检测我的独立 GPU，似乎选择了正确的驱动程序，并检测到已启用 OpenCL-OpenGL 互操作：

我不知道接下来该怎么办。这可能是已知的 ATI Ubuntu 12.10 问题遗留的问题，也可能是新问题。有人有什么建议吗？
答案1
好的。搞清楚了（至少在我的情况下）。链接器未找到libGL.so文件。添加/usr/lib/fglrx
LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/usr/lib/fglrx
到我的~/.bashrc（或~/.profile）使它工作。但这不应该是必需的，因为驱动程序安装程序会添加/usr/lib/fglrx到/etc/ld.so.conf.d/x86_64-linux-gnu_GL.conf文件中。
编辑说明：我之前的帖子将此错误归咎于 Cinnamon（错误 1483）；然而，这是不正确的。记录的解决方案是正确的。
