so i turn off my laptop and many hours later boot up and now my un/pw doen't not work in the login window. and yes i know im typing it correct and my keys arent sticky and no caps lock and such. only thing thats changed is i have ubuntu set to automatically d/l all updates and i have all the proposed ones enabled so there were a couple today that were ready to install but i have no idea what they were but can that even cause my login info to not work? i dont even know where to begin to fix this issue because it would be nice to have use of my OS but now im stuck booting into the xp partition, good thing i didnt go all in with ubuntu. anyone have ideas?
