I did a 'sudo apt-get dist-upgrade' a couple of weeks ago in Ubuntu 12.04 and was no longer able to boot into my system (Dell XPS 15z), getting the following error on a black screen that doesn't go anywhere:
On the grub boot screen I was able to select 'Previous Linux versions' and boot with 3.2.0-32 successfully.
After the latest upgrade (today) to 3.2.0-34, I thought the problem might have been fixed, but it gives the same error upon startup. But booting with 3.2.0-32 still works. How can I fix this so that I can keep up to date with the updates?
This may also be related: when installing Ubuntu 12.04 for the first time on this hardware I got some similar problems and resolved them as suggested on the forums by doing the following, but those settings still apply in the grub configuration:
Code:
