[Bug 135557] Re: Screen dimensions of external monitor not correct on X server startup (intel driver)

[Bryce Harrington]

** Description changed:

  Binary package hint: xserver-xorg-video-intel
  
  
  External monitor (24'', 1900x1200), connected via DVI (of the docking station) to a
  DellLatitude D830 (15.4'', 1680 x 1050).   The laptop lid closed and BIOS set to 'prefer
  docking station gfx if available.
  
  On the external monitor I see the following bugs:
  
    0)  after booting I see  a KDM login greeter with fonts and icons way tooooo big.
         (Monitor does autoscaling).   See 0th.Xorg.0.log
         I assume that the intel driver uses settings of laptop display instead the external
         monitor settings.
     1) then after login I can set with krandrtray to 1920x1200, but fonts are still too big.
         While pixel number is corrrect  now , the screen dimension (in mm) used is still of
         the laptop display  and from the external monitor.   See 1st.Xorg.0.log, 1st.xrandr.log,
         and 1st.xdpyinfo.log
  
  When I then login the KDM login greeter looks perfect (# of pixels and size) and after
  login again  and using krandrtray to switch to 1920 everything looks fine:
