permanent problems after changing compiz options in 11.04

[SidebySide]

I've installed AriOS (http://arioslinux.org/wp-signup.php?new=en) 3.0.1 (http://www.webupd8.org/2011/07/arios-30-released-ubuntu-1104-remaster.html) which is a remaster, based on Ubuntu 11.04. It doesn't use Unity, so, I followed this guide (http://www.webupd8.org/2011/05/how-to-downgrade-to-compiz-086-in.html) to downgrade Compiz to get rid of system crashes. I downgraded. then I Import this file (http://forum.pinguyos.com/attachment.php?aid=386) (which has hinted in the mentioned guide) to compiz via ccsm.
now I have this problem:
after choosing ubuntu into grub, right a moment before loading desktop, it seems restart suddenly(because my monitor start twinkling for a short time and if DVD-Rom is ejected, it reback the same as restart time!) after this event, so fast, desktop load up sucessfully!
What is happening?

Oops! a new problem;
I use above file for compiz options into my main system using 10.04. This problems raised up:
1. PrtSc(Print Screen Key) don't work!
2. I should add nomodeset after quiet splash in grub menu to be able to start desktop, whitout "nomodeset", desktop don't come up and monitor twinkles when CPU is working?
What's wrong? How can I solve this problems.
Before importing that damn file from Compiz, every things worked nice.
