Hello,
I've got two questions without answer, maybe because I don't found it in the
documentation, or maybe because I just don't understand it in the doc.
First, I'm trying to use VirtualGL on a server without plugging a screen on
the graphic card.
I already configured vgl with vglserver_config, and with this, I'm able to
use VGL without the need to open a session before.
But if I try with no screen plugged on the graphic card, I just get the
classical "[VGL] ERROR: Could not open display :0." (same with xdpyinfo
-display :0 ).
So how can I be able to use the capabilities of VGL without screen ?
The other question is related to the use of multiple GPUs with Xinerama. The
VGL doc says :
VirtualGL can redirect the OpenGL commands from a 3D application to any 3D
graphics card in the server machine. In order for this to work, however, all
of the 3D graphics cards must be attached to different screens on the same X
server using Xinerama. They can then be individually addressed by setting
VGL_DISPLAY to (or invoking vglrun -d with) :0.0, :0.1, :0.2, etc.
So, I want to do this, obviously without any plugged screen, and then I need
xinerama to create/attach the displays I suppose.
How to do this then ?
Thanks for answers guys, and don't hesitate to request more informations !
Have a nice day.
Philippe.
