I went back pretty far, into the 4.x versions, and still had the same
results, so I'm guessing this isn't kernel-related. Any suggestion on
what else to try?

Strangely enough, it was my power adapter causing the problem. I don't

Sorry for the delayed response. Fn+Space turns the keyboard backlight and
Thinklight on, but does nothing for the screen brightness. Please also see
this report: https://bugzilla.kernel.org/show_bug.cgi?id=51131
Aaron at the end says we're depending on Nvidia for brightness control. Is
this true?
This is still an issue in 12.10, kernel 3.5.0-21-generic. I can
reproduce it by simply closing the lid on my Thinkpad T530. I have mine
set to only turn off the screen when the lid is closed and not suspend.
I can confirm that Adolfo's workaround of dropping to a terminal fixes
the issue.
