System:

Samsung 535u4c APU a6-4455 integrated Radeon HD 7500 dedicated HD7550 (hybrid graphics) Linux Mint Nadia based on Ubuntu 12.10 Quantal Quetzal

After installing the Catalyst driver 13.4 my notebook freezes randomly (not always ) during booting. Furthermore when linux started without freeze the mouse pointer when moving to the rightmost, gets out of the right site of the screen and appears then on the left side. I've tried different Catalyst version ( 12.10, 13.4, 13.6 beta) and the problem always persisted. I guess that the dedicated hd 7550 is not correctly detected. But I do not know how to solve it.

I'm a newbie to Linux and I would be very grateful for any proposal to resolve the problem.

Thanks in advance.

This is my fglrxinfo output:

display: :0 screen: 0 OpenGL vendor string: Advanced Micro Devices, Inc. OpenGL renderer string: AMD Radeon HD 7500G OpenGL version string: 4.2.12217 Compatibility Profile Context 12.104

display: :0 screen: 1 OpenGL vendor string: Advanced Micro Devices, Inc. OpenGL renderer string: AMD Radeon HD 7500M/7600M Series OpenGL version string: 4.2.12217 Compatibility Profile Context 12.104

This is part my dmesg output:
