I booted up to Ubuntu today only to find that my resolution has been changed from 1024 x 768 to 640 x something. It's so small, I can't even see the taskbar when I am in FireFox. I tried changing it by going to Preferences > Screen Resolution, but it only gives me an option for 640 and 320. Can anyone help me with this? I know I have the right drivers and everything because I was on it last night and it displayed 1024 x 768. Thanks for any help.
