I have a Pavilion dv6 laptop with a 1920x1080 display, running Ubuntu 11.04. This evening, after installing the latest updates, I can't set the screen resolution higher than 1280x1024. How do I troubleshoot this?

I figured out the problem. While trying to fix an unrelated problem, I made some changes outlined in comment 27 of https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/699802. Backing out those changes fixed my screen resolution.
