Touch PadPartialPointer starts jumping after a while with synaptics 1.7.4-0ubuntu1 in 14.04. Might be fixed in upstream.
Suspend/ResumeNo/MaybeDisplay remains black, or machine freeze. Did not debug.



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




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:


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:


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.)

    Identifier "intel"
    Driver "intel"
    Option "TearFree" "True"

Hardware Video Decoding

vlc can use the Intel i965 card for video decoding using VA-API
