Hi,

I can't get to install the proprietary driver "fglrx" with ATI Radeon HD
5970 on Debian Squeeze.
After the installation with ATI Catalyst 12-8 and a reboot, from the stage
of GDM, the screen is freezing with a lot of little squares appearing on X,
mouse is locking and total freezing of the system. I have tried with old
Catalyst versions and same problems.

I would like to install the proprietary fglrx driver because I need to use
bi-GPU of this card with OpenCL. With the free radeon driver, I have no
problem for X but I don't have GPU support.

I also try with "module-assistant" but the issue is the same.

Here's my config :

PC : Aspire G5900-090 - Core i7-870 - 8Go - HD5970 (2048Mo)

With free radeon driver, "CLInfo" tool of ATI stream SDK makes only appear

Has anyone already got this problem of freezing with the fglrx proprietary
driver on Radeon HD 5970 ? Could it be an issue with my screen or with
frequencies ?

Any help would really be appreciated
