[SOLVED]Gnome-shell won't start

Question

Hello. I cant start Gnome-shell and it force to Fallback. In addition to, in the Fallback mode, i can't change any parameters of gnome.
get this message when run the command:
gnome-shell --replace
(gnome-shell:18571): Gdk-WARNING **: The program 'gnome-shell' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadRequest (invalid request code or no such operation)'.
(Details: serial 132 error_code 1 request_code 139 minor_code 66)
(Note to programmers: normally, X errors are reported asynchronously;
that is, you will receive the error a while after causing it.
To debug your program, run it with the GDK_SYNCHRONIZE environment
variable to change this behavior. You can then get a meaningful
backtrace from your debugger if you break on the gdk_x_error() function.)
I have ATI Graphic card and installed Catalyst 12.4
How can i fix it?

Not enough information.
Are you starting Gnome through startx or GDM?
What is contained in .xsession-errors?
Do you have the testing repo enabled in pacman.conf?
Sorry for that i am new in GNU/Linux world and I didnt know what information had been needed.
Thank you for your answer.
I use GDM.
Testing repo is not enable.
