The monitor profiler in LPROF also supports the use of a measurement file 
generated by a color meter or a spectrophotometer.  If you have a way to take 
measurements then LPROF will generate a very accurate monitor profile.  If 
you have any ideas about how to improve the rough monitor profiler please 
post these to the LPROF tracker on sourceforge as the development team is 
very much interested in this kind of feedback. 

As Kia-Uwe Behrmann has pointed ArgyllCMS will create measurement files using 
several instruments so it is possible to do all of this stuff in Linux.  Just 
a little more difficult than in other OS's at this point in time.
