Downgrade XServer 1.19 to 1.10

When I try to install AMD Catalyst to my Kali Linux 2.0 detailed as below root@blackbox:~/Downloads/fglrx-15.302# uname -a Linux blackbox 4.9.0-kali3-amd64 #1 SMP Debian 4.9.13-1kali3 (2017-03-13) x86_64 GNU/Linux I get this following error. error: Detected X Server version 'XServer 1.19.2_64a' is not supported. Supported versions are X.Org 6.9 or later, up to XServer 1.10 (default:v2:x86_64:lib32:XServer 1.19.2_64a:none:4.9.0-kali3-amd64:) Installation will not proceed. And no new updated drivers were found in AMD's website. So I would like to downgrade my XServer to supported version. How do I do this? Details on my dedicated graphics card as below 01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Thames [Radeon HD 7500M/7600M Series] (rev ff) (prog-if ff) !!! Unknown header type 7f Kernel driver in use: radeon Kernel modules: radeon And is there a way to find out that the current generic driver supports automatic switchable graphics? And is there a way to find it? P.S I am relatively new to Linux. So please go easy on me.Thank You.
