use*_*662 5 debian gpu amd-radeon debian-squeeze amd-catalyst
我无法在 Debian Squeeze 上安装带有 ATI Radeon HD 5970 的专有驱动程序“fglrx”。用ATI Catalyst 12-8安装并重启后,从GDM阶段开始,屏幕冻结,X上出现很多小方块,鼠标锁定,系统完全冻结。我曾尝试使用旧的 Catalyst 版本和同样的问题。
我想安装专有的 fglrx 驱动程序,因为我需要在 OpenCL 中使用这张卡的双 GPU。使用免费的 radeon 驱动程序,我对 X 没有问题,但我没有 GPU 支持。
我也尝试使用“模块助手”,但问题是一样的。
这是我的配置:

有没有人在 Radeon HD 5970 上遇到过 fglrx 专有驱动程序冻结的问题?可能是我的屏幕或频率的问题?
任何帮助将不胜感激
