This is the expected case with the current tree :)

This means that there's a problem in your testing environment: some other
application needs to be killed. Please retest.
(I recently sent an email to Gordon Jin with a possible BKM to share with QA
regarding this error message)

This means you don't have any attached screens that are either DP, HDMI or VGA.
The "lpsp" test needs an eDP output, the "non-lpsp" test needs non-eDP outputs.

Same thing here.

Considering that we merged Daniel's DPMS work a long time ago, and that the
expectation is that everything works fine, I really think we should close this
bug report, and then consider any other possible failures regarding the "dpms"
tests as new bugs.
