[Paraview] Is it possible to prevent the render window to appear when using a python script?

[Masquelet, Matthieu (GE Global Research)]

OK I feel a bit silly. Is the mailing list indexed in google? I spent 2 hours this morning looking for this and I guess I didn't search directly in the mailing list archive... Thanks for the tips... Rebuilding pv with OSmesa is out of my control right now so I will give the X server solution a shot.

Matthieu,

This question comes up quite frequently on the list, in fact just yesterday. There is Andy's suggestion of reverting to OSMesa for rendering to get rid of the window (at the expense of not using graphics hardware any more):

You might try the solution Pat suggested in case you are using Gnome

I haven't tried it in quite a while, but I reckon using a separate X server as Kevin suggested a few years back should still work, too:
