Switchable graphics Intel + AMD Venus Pro

I'm using Manjaro Linux on my laptop with switchable graphic cards:

00:02.0 VGA compatible controller: Intel Corporation Haswell-ULT Integrated Graphics Controller (rev 0b)

03:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Venus PRO [Radeon HD 8850M / R9 M265X] (rev ff)

Here's a screenshot of the drivers section of Manjaro Settings Manager: The above shows that bumblebee's drivers are installed, but the daemon fails: [luke@manjaro ~]$ sudo systemctl status bumblebeed ● bumblebeed.service - Bumblebee C Daemon Loaded: loaded (/usr/lib/systemd/system/bumblebeed.service; enabled; vendor preset: disabled) Active: activating (auto-restart) (Result: exit-code) since pią 2015-09-18 16:22:55 CEST; 29s ago Process: 1192 ExecStart=/usr/bin/bumblebeed (code=exited, status=1/FAILURE) Main PID: 1192 (code=exited, status=1/FAILURE) wrz 18 16:22:55 manjaro systemd: bumblebeed.service: Unit entered failed state. wrz 18 16:22:55 manjaro systemd: bumblebeed.service: Failed with result 'exit-code'. During my trial-and-error I also tried to install video-catalyst driver (in window shown above). It ended miserably - after the initial startup the screen was full white. I switched to another TTY and deleted video-catalyst using mhwd. My goal is to be able to play games on Steam. What can you recommend?
