            Bug ID: 261440
           Summary: vt newcons breaks suspend/resume for all graphics
                    cards that do not use KMS drivers
           Product: Base System
           Version: Unspecified
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Many People
          Priority: ---
         Component: kern
          Assignee: bugs@FreeBSD.org
          Reporter: sblachmann@gmail.com

vt newcons breaks resuming from S3 suspend for all graphics cards except th=
ose
being supported by i915kms, radeonkms and amdgpu.
Screen is black at resuming.

With sc resuming works just fine.
It does not matter whether the open-source freedesktop drivers are being us=
ed
(pre-radeonkms ATI graphics cards, Matrox, S3, ...) or the proprietary nvid=
ia
drivers, sc handles them well, unlike vt.
