Hi all,

I have a HP pavilion dv9727us laptop, with nvidia geforce 7150M graphics.
When i play a video file (movies,...) with compiz enabled, the screen freezes every ten minutes, and then comes back to normal after a short while (about 30 seconds).

The real problem is that this happens on any distribution and the only solution is to disable compiz.
Is there a way to fix this?

Thanks in advance.

I forgot to tell that compiz runs pretty good,
compiz benchmark is 240 FPS,
glxgears shows 1400 FPS.

Thanks.

compiz running on a laptop uses the CPU ( not the GPU) ,If the correct is not installed .so turn it off when playing videos .

Thanks for the reply,

I did a quick search on google, it seems this happens only on nvidia chips!
Does anyone have this problem with a different chip?

P.S. I found from 'nvnews.net' that adding the following option to xorg.conf will fix it on many machines:

I'll try this and post the results.

Uh? Compiz doesn't know the shape of your computer case :P It doesn't care if you use a laptop, a PC or a Playstation as long as X is running and your driver supports the needed gl extensions. The applications do not have direct access to the hardware so compiz doesn't see anything, it just speaks to X and the gpu driver.

The one which decides where does each instruction goes at hardware level is the graphics driver. And there are mobile acelerated gpus for all the main gpu makers (nvidia, ati and intel, probably some other minor ones).

Maybe I misunderstood you or something.


About the topic, my solution would be to drop compiz, but I doubt that's the solution your are looking for :P

Um..., not bad! (not impressive though)

I tried the option and it decreased the times the screen freezes, it also takes shorter to go to normal state again.
The rating! : delay between freezes are about 25 to 30 minutes, and it takes only 4 seconds.

Now i'm sure it is the nvidia driver or X (at least something to waste time with!).

Any more ideas?
