[SOLVED] Gnome-shell won't start

[vahid_d]

Hello. I'm not very professional in GNU/Linux world and recently started to install Arch linux. But 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 (HD6850) and installed Catalyst 12.4
Seems Catalyst installed without any problem and it's control panel works.
I use GDM and the testing repo is not enable.
And the .xsession-errors contains:

[vahid arch ~]$ cat .xsession-errors

KDE works but im not sure the catalyst works well too. is there any way to check Catalyst?
I dont like KDE I wanna work with Gnome, even older versions of it.

The problem solved with updating Catalyst to new version (12.6)
