DualHead + 3D acceleration -> system freezes

[Ragzid]

Hi all,

I use Ubuntu 6.06 (Dapper, kernel 2.6.15-28-386), ATI x1600 Pro in AGP and 2 CRT monitors. The primary monitor is connected via DSUB to DVI reduction to DVI port, and secondary to DSUB. I try to make my 3D accelaration running, so I installed fglrx from repository (version 8.25) and accorting to HOW-TOs I got

$ glxinfo | grep direct
direct rendering: Yes
direct rendering: Yes

If I run glxgears -prinfps, all is ok, average fps is about 2900. But fgl_glxgears is problematic, after a while my system freezes, the keyboard is not responding, I can move only with mouse, but it is locked at primary screen. The similar situation is if I started a game, for example TuxRacer, system freezes too after a while...
Have somebody any idea what can causes this freezing?

In xorg.0.log are no errors, only warnings:

$ cat /var/log/Xorg.0.log | grep WW
        (WW) warning, (EE) error, (NI) not implemented, (??) unknown.
(WW) fglrx: No matching Device section for instance (BusID PCI:1:0:1) found
(WW) fglrx(0): board is an unknown third party board, chipset is supported
(WW) fglrx(1): board is an unknown third party board, chipset is supported

(WW) fglrx(0): Option "ModelName" is not used

So, I solved this problem.

I was browsing some czech phorums and I found a link to script called envy. This script downloaded the latest drivers from ATI web, reconfigured fglrx kernel module, configured xorg.conf and freezing is away
