[IDV #XBM-123122]: Fwd: Error IDV amb Xvfb

Hello Víctor.

So to summarize, this problem is specifically isolated to -trace flag. Out of 
curiosity, why do you run the IDV with the -trace flag? If the trace option is 
important, I would suggest trying the trace tag in the ISL, and omitting the 
-trace flag from the command line, although it is possible this solution will 
still fail. See 
http://www.unidata.ucar.edu/software/idv/docs/userguide/frames.html for 
details. Let us know the results of this experiment.

Best Wishes,

Unidata IDV Support
