7950gt - Random (very often) freeze at X startup

[chareos]

Hi all,

today I bought a 7950gt card.
Previously I had a 6600 fanless.

With my new card I'm seeing random (very often) freeze at X startup.

I tried to force (with success) the videocard fan to a very high value with nvclock right before X startup. So I'd exclude any overheating issue.

Now, my first guess is about my power supply (19A on 12V, 7950gt suggest at least 20A I think) which I'll swap tomorrow just to be within min specs.
Anyway, the rare times X starts fine, I found I can run beryl, 3d games... with no crashes or instability.

What do you think about this ?
May be really the power suppy problem ?
Maybe the system is really on high load during X start and triggers the power supply poor rating ?


Thanks for any ideas.

Fabio

Thanks for your interest.

Unfortunately, the link you provided me was far from my situation (Single 32bit CPU, kernel 2.6.20.4 , latest non-beta drivers).

I also checked http://www.nvnews.net/vbulletin/showthread.php?t=46678
and I'll try to restart system up to XORG yet to begin, then startx verbose and get a log.
Unfortunately, it seems that problem does not occour if I login to a multi-user mode without X then I start X manually.

I'm starting to think that the system may be under heavy load when X starts concurrently with normal bootup process.
