I'm using the package gnuplot-x11 4.6.6-2 from Ubuntu.  I used the attached
scripts do_plot.m and run_do_plot.m to test x11, qt, and wxt terminals. 
For me, they all produce solid lines regardless of the linestyle.  If I
install the package gnuplot-qt 4.6.6-2, then gnuplot-x11 is automatically
removed, but at least the qt terminal will then show linestyles correctly. 
The 'wxt' terminal isn't recognized in this case, and 'x11' still doesn't
respect the linestyle.  It appears to be a visual thing only (although that
is still bad).  When I print the plot the line has the correct linestyle.

This doesn't affect me personally, I've moved up to gnuplot 5.0.3 to escape
the weirdness with 4.X.  This makes me agnostic about whether this gets
resolved for the release.
