Notes

Sound

Problem: alsa is using the HDMI audio output as first “default device”
Fix: Edit /etc/asound.conf

pcm.!default {
  type plug
  slave {
    pcm "hw:1,0"
  }
}
ctl.!default {
  type hw
  card 1
}

Graphics

Tested:

Catalyst

Using Catalyst it is only possible to use radeon or intel at a time. No application based switching.

14.20, 15.3, 15.7, 15.9 all show tearing on desktop and games.

/var/log/Xorg.0.log notes:

(II) fglrx(0): TearFreeDesktop is not supported on PowerXpress systems currently.

See Bug: http://ati.cchtml.com/show_bug.cgi?id=467

AMDGPU

Topaz/Iceland is supported by amdgpu from kernel v4.5-rc3. xserver-xorg-video-amdgpu is required and not available on trusty.

Older kernels will trigger the following bug:
https://bugs.freedesktop.org/show_bug.cgi?id=91330

Intel

Complete Tear Free alternative: Purge fglrx and use intel only with the following X11 configuration. (Switching to intel via amdcccle does not solve the tearing.)

/etc/X11/xorg.conf
Section "Device"
    Identifier "intel"
    Driver "intel"
    Option "TearFree" "True"
