The NVidia drivers was installed using the Additional Drivers dialog. Videos, in both Totem (the default video player) and VLC, are quite dark. The NVidia settings do not provide the color correction controls I've seen with previous versions (possibly due to PRIME). If I open Totem's display preferences, and try to change any value for brightness, contrast, saturation, or hue, the video window goes completely black. Clicking the "Reset to Defaults" button restores the video playback. When the screen is black, subtitles and audio play as per normal. I traced this down to the package vdpau-va-driver not being installed on the system. I presume this is a missing dependency. I did have vdpau-driver-all:amd64 installed, but this is probably unrelated.
