We just merged some SKL fixes that may affect all display-related tests. Please retest this bug against the latest drm-intel-nightly.
Comment 5 liulei 2015-03-10 03:35:31 UTC 
This issue still exists. The monitor can be lighted up after using command " testdisplay -i".

Is this still a problem with v4.3-rc kernels or later?
