Public bug reported:
The computer in question is a retina macbook pro 10,1.
I have a television that I normally connect to via the builtin HDMI port.
After the upgrade from Ubuntu 14.10 to Ubuntu 15.04 (and thus to the nvidia-346
driver), the television no longer recognizes the connection from the macbook
when I plug in the HDMI cable (although the Display Settings app,
nvidia-settings, and xrandr do (apparently correctly) see the TV).
I verified that I do see the correct behavior after downgrading to
nvidia-340, and also that installing nvidia-349 (from the xorg-edgers
ppa) does not remedy the issue.
