@JohanTriHandoyo
I can't reproduce this with RC1, see the gif animation below.
The Quadro FX 4800 has less than 2GB RAM? Maybe that is the issue. You can find the requirements here: https://www.blender.org/download/requirements/

We require a .blend file and simple steps to reproduce the problem.

Here's the .blend file. I also try it on my Ubuntu 18.04.2 LTS machine with GTX 1080 graphic card, create a new file, still the same result. No stroke appears on the surface. The steps are exactly like the .gif file Christina posted, except that i use ctrl-left click to create the curve. Thanks!

The problem only occurs when you try to activate the operator by the property editor.
The image_paint_poll returns false because the context is not a 3Dview (and makes sense, which 3D view to choose?).

The problem could be mitigated if the operator was normally called in when clicking on the 3D view (as already works with any other Stroke Method).
Here a solution to run the operator when clicking:

diff --git a/source/blender/editors/sculpt_paint/paint_curve.c b/source/blender/editors/sculpt_paint/paint_curve.c
index d9fd194e96f..893aa20238f 100644

       break;
   }
 
-  return OPERATOR_FINISHED;
+  return OPERATOR_FINISHED | OPERATOR_PASS_THROUGH;
 }
 
 void PAINTCURVE_OT_cursor(wmOperatorType *ot)

@brecht, can you take a look?

I don't think clicking should draw the curve, much too easy to misclick when editing the curve. Enter key can already be used for drawing.
