Ajustes de brilho e contraste não funcionam. Uso o totem.Ajuda ai gente!?!

:heeeelllllooooo: Olá. Acabei de instalar o ubuntu 8.04 numa pcchips a15g tudo está ok com excessão do totem. Os controles de brilho e contraste não tem qualquer efeito. Já dei os seguintes comandos:

sudo wget http://www.medibuntu.org/sources.list.d/hardy.list -O /etc/apt/sources.list.d/medibuntu.list

wget -q http://packages.medibuntu.org/medibuntu-key.gpg -O- | sudo apt-key add - && sudo apt-get update

sudo aptitude install ubuntu-restricted-extras nautilus-script-audio-convert totem-xine cpdvd regionset x264 gqmpeg mp3gain mjpegtools libdvdread3 mpeg2dec vorbis-tools id3v2 mpg321 mpg123 libflac++6 ffmpeg cdda2wav toolame libmp4v2-0 lame lame-extras libmad0 libjpeg-progs libmpcdec3 libquicktime1 flac faac faad sox toolame ffmpeg2theora libmpeg2-4 uudeview flac libmpeg3-1 mpeg3-utils mpegdemux liba52-0.7.4-dev a52dec gstreamer0.10-ffmpeg gstreamer0.10-fluendo-mp3 gstreamer0.10-fluendo-mpegdemux gstreamer0.10-gnonlin gstreamer0.10-pitfdll gstreamer0.10-plugins-bad gstreamer0.10-plugins-farsight gstreamer0.10-plugins-ugly gstreamer0.10-sdl gstreamer0.10-plugins-bad-multiverse gstreamer0.10-schroedinger gstreamer0.10-plugins-ugly-multiverse rar unrar unace p7zip p7zip-full p7zip-rar arj unzoo lha mencoder libxine1-plugins libxine1-ffmpeg

sudo update-alternatives --config totem escolhi o totem xine mas parece ter ficado dividido, asteristico marcando para um e sinal de + para outro.

sudo apt-get install totem-xine
sudo apt-get remove totem totem-gstreamer

ai depois desse, excluiu todo o totem.

Estranho pois no outro pc que tinha apliquei o tutorial e funcionou de primeira, e usava o totem xine.

Como fazer para usar apenas o totem xine e brilho e contraste funcionarem ? Será que tem relação com o xorg?
Obrigada!
