  Binary package hint: xserver-xorg-video-intel
  
  I have a Dell 510m Inspiron laptop (Pentium M) with a i855 video chipset
  and a 1400x1050 LCD screen. With Ubuntu Hardy it worked like a charm,
  without any hack such as the infamous i195resolution. I just upgraded to
  Jaunty and the resolution is wrong: it looks lower (somewhat 1024x768)
  with still 1400px wide lines wrapping around, in an 'interlacing' style.
  Xrandr and xdpyinfo are sure they're running 1400x1050 and obviously the
  frame buffer is 1400x1050, although it's displayed in a quite unreadable
  "folded" fashion (it's not scrolling, it's wrapping).
  
  I've tried various hacks (using FBDev, explicitly setting Virtual sizes,
  etc) to no avail.
