Pessoal, aconteceu uma coisa muito estranha com meu computador. Minha 
placa de vídeo estava funcionando bem certinha, podendo me comunicar em 
videoconferência com o gnomemeeting. De ontem para hoje, ela parou de 
funcionar. Chequei o meu syslog e verifiquei o seguinte (é meio extenso, 
mas peço que tenham paciência):

Penso que quando ela (placa de captura de vídeo) estava funcionando, 
ontem, da última vez...
