54.0 (64-bit) from Canonical. It actually gets pretty awful -- for 
instance, the search box drops its little menu and that one is 
*transparent* with white text, making it unreadable. Additionally, several 
applications have reversed text and everything else is black background -- 
Settings > Additional Drivers from the main menu is one; particularly bad 
for me is that GThumb, which has no useful Trinity alternative, is also 
black with white text, which makes photo editing (my job) really 
difficult.

Where and how might I do that? Is there a GTK control center app equivalent 
to KControl?

Thanks for your help.
