    11.10 to 12.04 now no video display

    So I just finished taking my old HP ProLiant ML350 G3 Tower from 11.10 to 12.4 and now I have no video. Just my monitor with the ever so annoying "Cannot Display This Video Mode" msg. Anyone have any suggestions before I take it back to 11.10?

    You moved to 12.04 How?
    I mean, did you use the 12.04 live cd and do a new install or are you talking dist upgrade?

    Have you tried adding nomodeset to the boot arguments ?

    Got it fixed.
    @carl4926 Thanks for the nomodeset recommendation, but i couldnt even get grub to load.
    To answer your questions though, the upgrade that caused the problem was the distribution upgrade.

    The fix finally came after about 4 hours of combing through various forums with no luck.
    I decided to try to reproduce rather than just do a clean load of 12.4.

    I did a clean load of 11.10. Downloaded the 12.4 Desktop Live CD and tried the upgrade with it, and got the same result.

    Finally after the 3rd reload of 11.10, I decided to try the Alternate Installer DVD and upgraded using nomodeset option, rebooted and now I have video.
