Thanks. Apparently, the driver only detects the internal display in both
cases. You're saying neither case works with this config file? Does it
make a difference if it's already docked on bootup? Or if you use Option
"MonitorLayout" "TMDS" when docked?

You may want to look at
https://bugs.freedesktop.org/show_bug.cgi?id=3621 . Unfortunately, it
looks like LVDS+TMDS is still not working with the superpatch referenced
Speaking of upstream bugzilla, you may want to report this problem there
as well, assuming it hasn't yet.
