In case the video is still suspected:
pat@wopr:~$ xrandr
Screen 0: minimum 8 x 8, current 9600 x 2160, maximum 16384 x 16384
VGA-0 disconnected (normal left inverted right x axis y axis)
LVDS-0 disconnected (normal left inverted right x axis y axis)
HDMI-0 disconnected (normal left inverted right
I see 9% consistently, and as with those above, clock_gettime seems to
be the culprit:
pat@wopr:~$ sudo strace -c -p 29333
[sudo] password for pat:
strace: Process 29333 attached
^Cstrace: Process 29333 detached
