X freeze with proprietary fglrx driver on radeon HD 5970
 

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)

*** $ lspci | grep ATI

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

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
