My Acer Aspire 5336 laptop has the same problem. It occurred in Ocelot but was cured by editing etc/default/GRUB. After upgrading to Quetzal it recurred and I don't know what to do to fix it. Booting Quetzal leads to a complete blackout. It is possible to boot up in recovery mode, but only in 768 x 1024 video and simple graphics. The approach in the post above gives the same result. Who can help?
