I think I've discovered mostly what had gone wrong - somehow in the process of going quantal->raring, either the various colour balance settings in totem got changed, or it changed how it interpreted the numerical values in dconf. When I dug around in dconf-editor, I found various colour-related settings under org.gnome.Totem, which, once reset to defaults, caused my display issue to go away.
The problem was exacerbated by bug 1162389 - the totem preferences dialog has become inaccessible - hence why I had to resort to dconf- editor to change them. Thus, this bug becomes a question of how a visually sensible colour configuration on quantal ended up looking wrong after upgrading to raring. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1158594 Title: Video is too yellow/bright, as if a grossly exaggerated gamma transform is applied (raring regression) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/totem/+bug/1158594/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
