[VirtualGL-Users] VirtualGL on Sun Ray

[Jeroen De W. <jer...@in...>]

Hello,

We are trying to configure a Sun Ray server to interact with VirtualGL.
We wonder if it is possible to have VirtualGL use the graphical 
acceleration hardware of a Linux machine and send the rendered images to 
the Sun Ray Server Software?
Or if it is possible to have VirtualGL use the graphical acceleration 
hardware and send the rendered images directly to the Sun Ray Client?

We've tried to set up the desired situation by running vglclient on the 
Sun Ray session and setting the following environment variables:
VGL_DISPLAY=:0.0
VGL_CLIENT=:11.0 (11.0 is the display number used for the Sun Ray session)
DISPLAY=:0.0

When we execute vglrun to accelerate glxgears: vglrun -c 1 glxgears, we 
get the following error:
[VGL] pbuffer--
[VGL] 111: Could not create Pbuffer

It should be noted that when we do not set the DISPLAY environment 
variable to :0.0, the vglrun software tries to connect to display :11.0, 
even though VGL_DISPLAY is correctly set

We've also tried not using vglclient, and thus not using compression 
(compression would only slow things down, since we're running the Sun 
Ray Server on the same machine as the virtualGL server), but we get the 
same error...

Any help would be most appreciated

Kind regards,
