[Paraview] Why is pvbatch displaying images?

[burlen]

Hi All,

This question of pop-up windows comes up all the time, so I thought I'd 
report on a second option of configuring a second X-Screen. most of the 
time this will provide better rendering performance vs using OSMesa. 
Once you configure x this way you can launch pvserver/pvbatch on the 
second screen (eg. DISPLAY=:0.1 pvbatch ...). it seems that most recent 
graphics hardware (intel, ati, nvidia etc) can do this(link below). I've 
been using this on my workstation with nvidia and it works well. 
nvidia-settings was able to configure X for me. On other hardware it may 
be called Zaphod-heads. http://en.gentoo-wiki.com/wiki/X.Org/Dual_Monitors
