Title:
Brightness, contrast issues (possibly NVidia specific) in totem and
VLC
Status in totem package in Ubuntu:
Incomplete
Status in vlc package in Ubuntu:
Incomplete
Bug description:
This issue pertains to a fresh install of Ubuntu 17.10 on a Dell
Precision 5520 with NVidia 384.111-0ubuntu0.17.10.1 drivers installed.
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.
