I'm running Ubuntu 12.04 on a Dell E6230 with full disk encryption (not just homedir) as setup by the installer. In order to get the touchpad to be recognised and enable two finger scrolling I installed the linux-image-generic-lts-quantal package using apt which apparently has the required fix. The 3.5.0-40 kernel provided by that package doesn't boot. I supply the passkey for the disk but the boot stops. The last line printed to the console with graphical boot disabled is:
Stopping save kernel messages
How do I debug or fix this? Thanks!
The standard 3.2.0-53 kernel boots fine (but I don't have a fully usable trackpad).
