To me it does; I think the issues sound likely to be at least very
closely related, so for now I'll hold off on filing my issue as a
separate bug.  Tormod, please let me know if you think otherwise.

I should also mention that as my LVDS has a max resolution of
1400x1050 (i.e. lower than the max resolution of the external
monitors), I'm doing "xrandr --output LVDS --off" whenever I switch[1]
to using the external monitors -- so that might be why I'm not seeing
any "nonsense".
