我无法在 Debian Squeeze 上安装带有 ATI Radeon HD 5970 的专有驱动程序“fglrx”。安装 ATI Catalyst 12-8 并重新启动后,从 GDM 阶段开始,屏幕冻结,X 上出现许多小方块,鼠标锁定,系统完全冻结。我尝试使用旧版本的 Catalyst,问题相同。
我想安装专有的 fglrx 驱动程序,因为我需要将此卡的双 GPU 与 OpenCL 结合使用。使用免费的 radeon 驱动程序,我使用 X 没有任何问题,但我没有 GPU 支持。
我也尝试使用“module-assistant”,但问题是一样的。
这是我的配置:

使用免费的 radeon 驱动程序,ATI stream SDK 的“CLInfo”工具仅使 CPU 出现:

有谁遇到过 Radeon HD 5970 上的 fglrx 专有驱动程序冻结的问题吗?这可能是我的屏幕或频率的问题吗?
任何帮助都将不胜感激
答案1
目前,这些fglrx
驱动程序只能称为测试版驱动程序。支持非常糟糕。但是,使用这些方法。
但在执行此操作之前,请确保使用以下命令清除当前驱动程序:
sudo apt-get remove --purge fglrx fglrx_* fglrx-amdcccle* fglrx-dev* xorg-driver-fglrx
这是唯一的行动方案,每个人都抱怨图形有故障,不幸的是,由于 AMD 方面提供的支持很少,因此无能为力。
