    boot issues: Grub? on 12.04 LVM w/ disk encryption

    All, any help resolving this boot issue would be great!

    my assumption is that there is an issue with grub, but i'm not really sure.

    OS:
    Ubuntu 12.04 LTS 64bit running full disk encryption
    Background:
    I ran updates and a video driver update and rebooted.
    system came up and prompted for crypto password and then booted to a blinking cursor.
    I was still able to SSH to the box so I assumed that the video driver caused X to not load. ran through a tut. to remove video driver and reinstall X. then rebooted

    at this point system wouldn't boot at all. monitor screen would display "unsupported video format" and would go into sleep mode.

    I assumed that somehow grub was messed up and ran through a boot repair which provided this: http://paste.ubuntu.com/6904979/

    not sure where to go from this point.
    I get a grub menu on boot, but after picking an option I come to the same blanks screen with "unsupported video format"

    from a live-usb I am able to mount and unlock LVM partitions. all data and file structures seem are present.

    where to go from here?? I'm just not sure.
    any suggestions?

    thanks in advance,
