On a Lenovo T400 laptop with the GM45 Express Chipset, xrandr shows this puzzling non-existent "monitor": DVI1 connected (normal left inverted right x axis y axis) 1024x768 60.0 800x600 60.3 640x480 59.9 This is true regardless of whether or not an external monitor is connected. Worse, if I open the "display preferences" this phantom monitor shows up as "Unknown". I now know what to expect, but this is frankly confusing.
That it exists at all is because there's an optional dock for that machine with a DVI connector. That we think it's connected is, well, wrong. What's the full xrandr output for this machine?
This is when an external monitor is connected and active: Screen 0: minimum 320 x 200, current 1920 x 1200, maximum 8192 x 8192 VGA1 connected 1920x1200+0+0 (normal left inverted right x axis y axis) 550mm x 344mm 1920x1200 60.0*+ 1280x1024 75.0 1152x864 75.0 1024x768 75.1 60.0 832x624 74.6 800x600 75.0 60.3 640x480 75.0 60.0 720x400 70.1 LVDS1 connected (normal left inverted right x axis y axis) 1440x900 60.2 + 50.0 DVI1 connected (normal left inverted right x axis y axis) 1024x768 60.0 800x600 60.3 640x480 59.9 DVI2 disconnected (normal left inverted right x axis y axis)

But when I choose to maximize a window it fills the 1024xsomething area and the window decorations/edges are corrupted. Turning off the 2 fake DVI? appears to fix both of these problems.
I snapped my x200 into it's docking station but still have NO external monitor attached. things look a little different.
