** Description changed:

  Binary package hint: xserver-xorg-video-intel
  
  This happened after upgrading my system from karmic to lucid.
  
  I can't use my external monitor at full resolution (1920x1080) the
  maximal available resolution is 800x600 :-S.

  DP1 disconnected (normal left inverted right x axis y axis)
  
  but, in xorg log i can see my monitor proper resultion:
  (II) intel(0): Modeline "1920x1080"x0.0  148.50  1920 2008 2052 2200  1080 1084 1089 1125 +hsync -vsync (67.5 kHz)
  and there is a weird message:
  (II) intel(0): Not using default mode "1920x1080" (monitor doesn't support reduced blanking)
  What is this? can't i force somehow to use this mode?
  
  Btw, i tried an another monitor, (its an older LCD panel, and i can use its maximal resolution 1680x1050)....
  And the weird thing is everything worked fine before update to lucid... 
  
  When i booting up my machine with connected external monitor, it is not usable too, monitor says "invalid hsync value" :-S
  (i use encrypted rootfs i havent tried the booting without splash... i'll try it...)
  
  I'm not sure about whether its a xserver-xorg-video-intel problem, maybe
  it is some DRM/kernel related issue...
