Estou tentando executar aplicativos webgl no meu navegador, mas sempre que eu tento, nada acontece, então eu pesquisei e descobri que extras ubuntu-restricted-extras podem ser instalados para habilitar o webgl. Um dos meus amigos instalou o pacote em seu sistema e conseguiu executar o aplicativo webgl que eu estava tentando executar. Quando eu tentei instalar o pacote usando o ubuntu software center, o download parou e eu tive que matar o processo.
