It's perfectly normal that some tests are skipped, but you obviously do need to set the DISPLAY environment variable appropriately for the piglit run. Something like
DISPLAY=:0 python2 piglit-run.py ...
I meant that some tests are skipped when run remotely, but tested when run locally. ;) I'll try your suggestion.
