Thanks a lot for that tip! Yes, that indeed was the problem.<br>
<br>
I was just wondering....why does the GPU rendering have to depend on
the monitor at all? Since the GPU cards are doing the processing (at
least as far as i know)...is there any way in which one can remove this
monitor dependency altogether? <br>
Also, if it is not possible to do gpu rendering without a monitor, then
is it impossible to use the gpu's present in a cpu+gpu cluster(with
headless nodes)?<br>
<br>
I also tried xvfb, but it seems that it does not use the graphics cards
at all, and i got terrible graphics.<br>
<br>
Thanks again,<br>

Hi Pratik,<br>
<br>
I have had some similar issues when my desktop screen resolution was
higher than the server display resolution. Do you know what the display
resolution is set to on the server side? I was able to check the server
side resolution using xrandr command. The issue was fixed by increasing
the server display resolution in the xorg.conf. This could be one
possibility for what you are seeing.<br>

everyone, <br>
This is my configuration(PV v.3.10.1): <br>
Server: desktop with 4 NVIDIA tesla C1060 cards; Client is a laptop. <br>
To make use of GPU rendering, i start an Xserver on a free display like
so(i cannot use the :0 display, also i cannot use $DISPLAY. if i use
the $DISPLAY option, the server disconnects as soon as i load data from
paraview): <br>
<br>
startx -- :14 <br>
<br>
and my .xinitrc contains <br>
<br>
exec xdm <br>
<br>
so that xdm executes on the Xserver that is started. <br>
once this is done, i simply run <br>
<br>
mpirun -np 4 pvserver -display localhost:14.0 <br>
OR <br>
pvserver -display localhost:14.0 <br>
<br>
<br>
Everything goes fine, client connects to server etc. But when the
actual visualization is done, a strip at the top (roughly 1/3 of
screen) is blanked(see the attached image). A curious thing that i
observed was that when i change the orientation, rotate the object etc,
the LOD actor seems to render properly(meaning that i can see the whole
picture), but after i let it settle then this clipping takes place.
Only a few weeks back the rendering seemed to have happened perfectly,
so i don't know why it is suddenly behaving this way now. <br>
<br>
Thanks in advance for the help. <br>
