I'm seeing similar, but for me it happens after logging in from screen-lock,
possibly after laptop was suspended (but not always).  Usually it's both
monitors (laptop and external), and the Brightness sliders usually match the
actual brightness.  But today, for example, both monitors were dim, the laptop
slider was at 0%, but the external slider was at 100%. So the external slider
position did not match the actual monitor brightness.  

When I moved the sliders, each monitor reacted correctly.  So far, moving the
sliders always corrects the problem for me.  

It would be useful if a dev could suggest some things to check to help with
diagnosis.  Is there something in syslog?  Something to check in dbus?
