[Bug 385832] Re: lower reslutions no longer available on LVDS with 2.7.99

[Geir Ove Myhr]

>From the attached Xrandr.txt it doesn't look like the EDID information has been successfully captured. Would you mind adding 
  Option "ModeDebug" "true"
to the "Device" section of your xorg.conf and upload the resulting Xorg.0.log. You may also remove/comment out the other Option lines in that section, as they should all be redundant or meaningless with the new driver. Also, the file ~/.config/monitors.xml.txt might interfere with what the driver normally does, so for testing purposes, it would be nice if you can rename that. Finally, it would be nice if you could comment out the SubSection "Display" in your "Screen" section, just to eliminate that as a source of the problems (it may be necessary for dual-head, but let's simplify as much as possible for testing).

** Summary changed:

- lower reslutions no longer available on LVDS with 2.7.99
+ [i965gm] lower reslutions no longer available on LVDS with 2.7.99 (KMS)

** Description changed:

  Binary package hint: xserver-xorg-video-intel
  
  Since the upgrade to the new intel xorg driver 2.7.99 from xorg-edgers
  on janty and the enabling of kernel modesetting, lower resolution for my
  laptop screen are no longer available:
  
  Current output:
  $ xrandr 
  Screen 0: minimum 320 x 200, current 1280 x 800, maximum 8192 x 8192
  VGA1 disconnected (normal left inverted right x axis y axis)
  LVDS1 connected 1280x800+0+0 (normal left inverted right x axis y axis) 304mm x 190mm
     1280x800       59.9*+
  TV1 disconnected (normal left inverted right x axis y axis)
  
  Before the upgrade also resolutions "1024x768", "800x600" and "640x480"
  were available. That means I can no longer mirror the LVDS with an
  external monitor with lower resolution (like a projector).
