I had a similar problem on my T40 with a projector (looked like an
800x600 window inside the projector's 1024x768 desktop), and found that
adding "extern_disp" and "intern_disp" lines to the Device section of my
XF86Config worked. Here's the section for my 16Mb Radeon card:
VendorName "Videocard vendor"
BoardName "ATI Radeon Mobility M6"
You might need to tap Fn-F7 a few times to get it to cycle between no
external output, only external output, and both lcd and external.
Hope this helps,
