Vc esta usando o Ubuntu 64bits? esse sintoma pode ser porque vc nao instalou o flash nativo para 64bits, se for esse o caso, de uma olhada
http://ubuntuforum-br.org/index.php/topic,66098.msg370033.html#msg370033 se vc desativar o compiz vc consegue colocar em tela cheia sem travar? Faça alguns testes clicando na janela do flash e desativando a aceleração de hardware, veja se retorna alguma coisa.
