Major opcode of failed request: 139 (ATIFGLEXTENSION) with Suse 11.3 and Radeon HD6320 grafic chip

I have a problem with the proprietary OPEN GL driver from AMD/ATI. After the successfull installation of the driver Catalyst 11.8 glxgears is not running anymore, hence OPEN GL software is not working at all.

Error message from glxgears is as follows
X Error of failed request: BadRequest (invalid request code or no such
Major opcode of failed request: 139 (ATIFGLEXTENSION)
Minor opcode of failed request: 66 ()
Serial number of failed request: 13
Current serial number in output stream: 13

Does anybody have a solution?
