Bug description:
  Description:	Ubuntu precise (development branch)

  N: Unable to locate package pkgname
  Error message box came up. System freezes. I had to reboot the computer several many times. When I start up Ubuntu 12.04 from the Grub boot menu. I get a error with the start up with the 'splash'. I have a Gateway 19" Widescreen High Def Monitor. Product Number: FPD1976W. From before, I couldn't see the Grub menu when starting up the computer. I would see Frequency Out Of Range.
