<pre>Jason suggested that Vulkan's lack of support for vblank_mode resulted in X
putting the display to sleep (and limiting fps to 1). This would stall tests
for long periods of time.
After executing `xset dpms force on` for the X session, hangs seem to have
ceased.
However, incremental_present tests intermittently fail on KBL. Jason suggested
modesetting vs sna as a possible difference for the default kbl config.
Xorg's log indicates modesetting/dri2 for skl and kbl platforms. skl passes
incremental present reliably.
These tests are disabled for kbl only.</pre>
