My 107d and Martin's are both Teslas. According to Wikipedia, his is a Quadro,
while my 107d is a GeForce. I have also two other Teslas, both GeForce, one
10de:06e4, for which I haven't installed 15.6 yet, the other 10de:0402, which
does not reproduce this:

None of mine have DMS-59 output though.

I don't understand this. My own NVidias have never while in my possession been
used with proprietary drivers. Mine normally run on nouveau kernel & drm,
modesetting DIX, as inxi suggests.

Does removing the DMS-59 and reinstalling, or a different Y-cable change
anything?
