Hello everybody!
I am trying to set up a VirtualGL server to render 3d volume objects. It
needs a lot of graphic memory and I would like to distribute the load in two
graphic cards. I have been reading another post where it was questioned
before but, leaving asside other issues, it sais that I just need to
configure two different X servers in my PC to get my server work. Ok, I have
set up two different xservers with the nvidia-settings tool but when I
execute the program like this: $vglrun -display :0 ./VolumeViewer Bunny.pvm
and everything runs as expected but when I try the same with the display nº1
it does not work at all: if I execute $vglrun -display :0 ./VolumeViewer
Bunny.pvm I just get [VGL] ERROR: Could not open display :1. I have tried
everytinhg I know. I would like to know if is there anyone that could help
me with my problem.
My xorg.conf file is the following:
Section "ServerLayout"
