<pre class="bz_comment_text">Use nvidia. I just installed ubuntu karmic koala with ubuntu perfect script, a pcchips A15G everything is ok except for the totem, the brightness and contrast has no effect. sudo apt-get remove totem-gstreamer sudo apt-get install totem-xine In player xine it works ok. In ubuntu 8.4 was in / home / sillas / .config / totem / xine_config and put what I wanted. In Karmic this file does not exist, but it includes no avail. Any idea? I'm positive, the monitor is fine. This problem started after I installed the karmic koala (installation by the live-cd). Before, I used the Hardy Heron and was ok. Everything was working in totem. In hardy I was able to uninstall the totem-gstreamer and switch to totem-xine, the karmic even following the same steps it does not. Already removed with apt-get and reinstalled and nothing changes.!? The gstreamer-properties does not help. Not even know what to do ... in the gstreamer-properties > Video > default output plugin > custom line: videobalance hue=-1 ! autovideosink and my video turns to red... I try videobalance hue=0 saturation=50 contrast=-50 brightness=1500 ! autovideosink Only shows me hue efects and not exist the colour balance in Edit->Preferences->Display This problem only happened in totem and always hapenned in ubuntu (7.10-8.04-9.10) but i was able to fit it and had compiz and cairo-dock with no error . Now I am using xine player (ugly) but is works. I really prefer totem and I hope fix to fix it. linuxubuntu lcn_brain is online now Please help me! <a href="https://bugzilla.gnome.org/show_bug.cgi?id=603640">https://bugzilla.gnome.org/show_bug.cgi?id=603640</a> </pre>
