Summary: Video Noise on HDMI output
Product: xorg
Version: unspecified
Platform: x86-64 (AMD64)
OS/Version: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: Driver/nouveau
AssignedTo: [email protected]

When the nouveau driver is used, bright whites have noise in them.
The picture is steady for all other colours.
Replacing the driver with the nvidia closed source one, the HDMI works fine. So
all cables must be OK, it must be a driver bug.
I suspect a HDCP problem. How do I tell if HDCP has negotiated correctly or not
with the nouveau driver?
If I use the nouveau driver, but instead with the DVI connector, and connect it
to an analogue VGA adapter to the same TV display unit, the output is fine with
no noise.
