--- Comment #8 from piranna@gmail.com 2012-03-03 03:09:48 PST --- Sorry for answer so late, this is not my main computer (it's my parents one).

Ok, after some regular usage (reading mail, surfing web...) with System Monitor at panel to see how system evolutes:

* CPU is always about 5-10% and system load about 0.5-1 * just moving the mouse CPU increases to 40% * browser scrolling (Chromium 17.0.963.56) increase CPU to 80-100% * loading a webpage with about 100 thumbnails freezes browser with CPU 100% about two seconds * Gnome Mahjongg gets frozen with CPU 100% at refreshing window when going from windowed to maximized and viceversa for about 2 seconds

Also i'm thinking about try with old Ubuntu Live-CDs to look for when started the regression.

I'll try to do the sysprof this afternoon (i need to learn to use it). Where must i use the INTEL_DEBUG=fallback flag? As kernel parameter un Grub?

And no, i'm not excited about rendering frames i will not see ;-) I disabled vsync just for try and it was the only thing that did relative small YouTube videos (320x240) didn't drop frames and get frozen... :-/ I really would love to have vsync back... :-D Oh, and i don't want to use compiz (i hate it and in fact i'm using a plain no-effects Gnome panel desktop), maybe just some games like Warmux or Quake 3 (this would be a good performance test to put in perspective since my old P3 1.1GHz computer with an i815 graphic card played it very good, i'll try later). Compiz was just an example that the graphic card was enought powerful to use it without problems... :-)

P.D.: i've attached the pending log files. It keeps some with boot flags, i'll try to upload later.
