Sabayon: scrolling && compiz.

This is not a Sabayon related problem. Probably is happening no matter what distribution is used but I will try with an Ubuntu Live just to be sure.

While looking for tutorials, tips, tricks to setup the Wacom digitizer i have to scroll a lot and every time i have huge problems. Because of scrolling, the entire system is freezing for a few seconds. This happens almost every minute and is pissing me off, really.

Watching the system load with top, i saw the Firefox and X using 100% of the CPU. After searching with google and checking tons of bug reports i found a few tips like: disabling smooth scrolling in firefox, adding “export MOZ_DISABLE_PANGO=1” in “/etc/profile“, adding:

Option "EnablePageFlip" "true"
Option "RenderAccel" "true"
Option "XAANoOffscreenPixmaps" "true"
Option "AccelMethode" "EXA"
Option "MigrationHeuristic" "greedy"

in “/etc/X11/xorg.conf” but unfortunately none of them worked for me.

Looks like the problem is related to Compiz and ATI drivers.
Not that firefox or xorg are working 100% fine.

The only workaround for me is to switch the window manager from Compiz to Metacity. Now, xorg and firefox are using under 40% of CPU when scrolling but at least the system is not freezing anymore.

If anyone have some tips how to fix this issue, please let me know.
Thank you!

1. What version of the ATI driver are you using? I try to keep up with the latest on ati.amd.com, I don’t notice scrolling issues in firefox (which I have had using compiz on nvidia and intel chipsets) but that being said I mostly use Arora and Konqueror for browsing.

2. I’m using the latest driver from sabayon repository.
   Soon i will check to see if on ATI web are new drivers. Anyway, compiz is causing me lot of problems.

   After latest Sabayon updates is not even working anymore

3. The drivers on the web are way newer. Not sure why the sabayon repo lags behind here.

   If your X is failing to do compiz after running updates you may have to do:

   eselect set opengl ati

   but it sounds like your situation is a little worse than that. That was the only serious problem I’ve had after doing equo world.

4. Well, this is not the only problem.
   Sound in Skype is not working anymore
   Probably something to do with pulse audio.
   I didn’t have too much time lately… i hope in weekend will be better and i will try your tip for compiz.
