I'm using Ubuntu 12.10 with the latest updates.
Pictures with no dark areas look ok. If there are dark areas, then they are
much brighter than in the camera processed jpgs.
If I enable the Zone System plugin with blend:multiplication the dark areas are
looking like in the processed jpg.
I'm working on a HP laptop with proprietary AMD display driver installed.
Sometimes I have an external monitor attached to it.
The output of
xprop -display :0.0 -len 14 -root _ICC_PROFILE
is _ICC_PROFILE(CARDINAL) = 0, 0, 4, 140, 108, 99, 109, 115, 4, 32, 0, 0, 109,
110.
Tested it with no external display attached.
Regards,
Markus

I got some A77 RAW from photographyblog.com and tested it locally on my own
(properly setup) system, where I get a pretty good match with regard to
tonality...

One thing which is easy to miss, is the fact that GNOME Color Manager
autogenerates a profile from the display EDID, which may influence things.
It's easy to see if a profile got set (as detailed in my article):
xprop -display :0.0 -len 14 -root _ICC_PROFILE
