How to install AMD Proprietary Drivers on Manjaro?

I'm using Linux Manjaro 0.8.13 on my laptop and want to install proprietary drivers. Here is what I have: efog# lspci | grep VGA 00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) 01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Thames [Radeon HD 7500M/7600M Series] (rev ff) At first, I've tried to install drivers using "Manjaro Settings Manager" and "Hardware detection". Right-clicked on "video-catalyst", then "Install", rebooted and got black screen without X. Then I've tried to install it manually. At first I downgraded my xorg-server to version 1.15. Here is all of what I did then: yaourt catalyst-test #conflict with mhwd yaourt catalyst-total-pxp #conflict with mhwd sudo mhwd -i pci video-catalyst #ok, but black screen Then I removed mhwd with -Rdd option and tried to install catalyst again.  I got this: Building fglrx module for 3.18.15-1-MANJARO kernel ...

I have only 1 assumption: efog# uname -a Linux efog-pc 3.18.14-1-MANJARO #1 SMP PREEMPT Mon May 25 01:26:15 UTC 2015 x86_64 GNU/Linux And in the .log file I see version 3.18.15-1.  But I really don't know what to do.
