This is a graphics driver problem.  If you are running Chimera on one 
machine and displaying on another then the graphics driver (or Mesa) on 
either machine could cause the problem, or they just aren't able to talk 
to each other. First thing I would try is install 1.5.3 (if you removed 
it) and see that it still works.  You can have Chimera 1.6.2 and 1.5.3 
installed at the same time.  Just put them in different directories.  I 
don't know of any difference between Chimera 1.6.2 and 1.5.3 that would 
explain why one would work and not the other.  You could also try the 
Chimera daily build.

Does Chimera crash when you load data or just when you start up? If it 
starts you should use Help / Report a Bug  so we know your graphic 
driver and other system info.
