I've found that this xorg.conf file allows 1024x768 on the internal monitor=
=20
when nothing external is attached and either a single virtual desktop=20
comprising both monitors (Xinerama=3Dyes) or two independent, but adjacent=
=20
desktops (Xinerama=3Dno). It works on a T40 (radeon M7) running XFree86 4.=
2,=20
4.3 and Xorg 6.7 and 6.8.
