I just installed ubuntu karmic koala, moatherboard is a pcchips A15G (Use nvidia.) everything is ok except for the totem, the brightness and contrast has no effect.
I try and try...

sudo apt-get remove totem totem-gstreamer
sudo apt-get install totem totem-xine
but seens like totem-gstreamer still there

In player xine it works ok.
In ubuntu 8.4 was in /home/sillas/.config/totem/xine_config and put what I wanted and was ok. In Karmic this file does not exist. Any idea?

Do not install it nothing, nothing removed.
I haven't changed the xorg.
I haven't changed the nvidia x server settings tools.
In gstreamer-properties -> video output-> custom-> pipeline:
tried several commands, which ran:
videobalance hue=-0 saturation=1 brightness=1 ! videoscale ! ffmpegcolorspace ! ximagesink

[...]
--
videobalance hue=-0 saturation=1 brightness=0.25 ! xvimagesink
--
videobalance hue=-0 saturation=1 brightness=0.25 ! autovideosink
--
The best command was "videobalance hue=-0 saturation=1 brightness=0.25 ! autovideosink"
For the internet I found some tips to "videobalance hue =- 1 ! Autovideosink" or "videobalance hue =- 100 ! Autovideosink" I decided to include the parameters you wanted, saturation and brightness using whole numbers and it worked.

The totem ran all night without problems, videos wmv, flv, avi and mp4 and mp3 with effects.
We do not understand why removed the totem-xine, which I personally think better and easier to configure. In ubuntu 8.04 xshm used, configured in / home / folder User / .config / totem / totem_config with everything ok. Pitty
This setting doesn't affect the players xine (xshm ) or mplayer, both are still working (saturation and brightness, etc.).

Hope that helps.
