Ugg, so imo X is really to blame here.  It's doing the right thing at close
time when it receives a hotplug event (detecting available outputs) but at open
time it's not bothering to restore the LVDS config.

This is actually why we don't do any reconfiguration in the kernel at event
time and why the console works fine; trying to do anything other than just
blindly restore the last config at open time is just guesswork.  If X is going
to listen for events it also needs to handle them correctly.

That said, doing load detect shouldn't affect the configuration, so we may have
to remove the drm_helper_disable_unused_functions() from our load detect code,
or use your patch from comment #13 to pick up changes correctly.
