everything went fine during install to the best of my knowledge,
on reboot my ubuntu was shot ,

loading bar popped up, loaded,
then got a flashing underscore,
it eventually gave me a couple errors, including an i/o buffer and something else,
but i forgot what it was.

15 minutes of sitting at a screen repeating those errors
and ubuntu finally opens
with a failed to initialize HAL warning

my resolution is also maxed at 1024x768.
everything was 1600x1200 before.

any idea how to get my system back to how it was ?
and then ill worry about linux mce.

thanks
