ATI Radeon 5800 系列双显示器统一不支持 3D 加速

ATI Radeon 5800 系列双显示器统一不支持 3D 加速

当我使用单显示器设置(没有 Xinerama)且使用我当前的 Ubuntu 11.10、ATI 5800 系列显卡时,Unity 会显示透明度、阴影等(尽管在控制/设置面板中图形被报告为“标准”)。

切换到双显示器设置后,戴尔 24 英寸 UltraSharp 和较小的 Acer 显示器,尽管我没有登录该显示管理器,但 Unity 仅显示为 2d。

WebGL 性能非常低迷,我感觉处理器正在完成所有工作,即使安装了驱动程序,卡也无法访问(从 ubuntu 存储库,我没有编译自定义驱动程序)。

关于如何启用完整的 3D 加速和视频卡支持的任何提示。

这是我的 xorg.conf 文件:

不要在 ATI/AMD Catalyst 控制中心启用 Xinerama。
