Tenho usado o Google Chrome com aceleração de hardware sem problemas e resultados muito bons no meu Dell Latitude E6440 14.04 Xubuntu com GPU Radeon. Ultimamente, (provavelmente devido a alguma "atualização do sistema" que faço regularmente como recomendado pelo Ubuntu), o Google Chrome parou de funcionar. Eu começo isso. Eu recebo o navegador e depois de 5 segundos todo o sistema trava !!! e preciso fazer login novamente.
Como posso fazer o google-chrome funcionar novamente? (modo de segurança, sem GPU?)
Como posso fazê-lo funcionar com aceleração de hardware como antes?
Aqui está o que eu recebi no stderr do google-chrome:
xxx@dellorian:~$ cat c.log
