Mint issues after update

view story

http://www.linuxquestions.org – The Story So yesterday I update Mint, it said something about not everything could be downloaded or accessed or something. I figure I'll update what I can anyway. Sounds good, right? Haha... Next time I go to boot up the computer, I see the login screen for the first time (before the monitor would say "no signal" after the BIOS screen for a couple minutes and then I'd be at the desktop screen). I think this is pretty cool, Mint now gets along with my monitor. I get a message about my session lasting less than 10 seconds after trying to log in. Not so cool. I click on details (HowTos)
