Some times passed from my previous mail, but I just right now try VirtualGL
2.2beta and discover a thing I never take care before :
I must launch a user session on my Ubuntu VirtualGL server to be able to
render from the server's graphic cards.
For example :
machine_A is the client.
machine_B is the server.
machine_A > vglconnect u...@machine_b
machine_B (with an open user session) > vglrun my_application
Result :
[VGL] NOTICE: Automatically setting VGL_CLIENT environment variable to
[VGL] 172.17.40.17, the IP address of your SSh client.
Polygons in scene: 62464
Visual ID of window: 0x21
OpenGL Renderer: GeForce GTX 295/PCI/SSE2
That's OK, the rendering is on the GTX 295 and the display is watchable on
the screen of machine_A
Now :
machine_A > vglconnect u...@machine_b
machine_B (on login screen) > vglrun my_application
Result :
[VGL] NOTICE: Automatically setting VGL_CLIENT environment variable to
[VGL] 172.17.40.17, the IP address of your SSh client.
Polygons in scene: 62464
No protocol specified
[VGL] ERROR: Could not open display :0.
So it warns me he can't open the display on the screen of machine_B.
Then I tried this :
machine_A > vglconnect u...@machine_b
machine_B (on login screen) > vglrun -d $DISPLAY my_application
Result :
[VGL] NOTICE: Automatically setting VGL_CLIENT environment variable to
[VGL] 172.17.40.17, the IP address of your SSh client.
Polygons in scene: 62464
Visual ID of window: 0x21
[VGL] WARNING: The OpenGL rendering context obtained on X display
[VGL] localhost:10.0 is indirect, which may cause performance to suffer.
[VGL] If localhost:10.0 is a local X display, then the framebuffer device
[VGL] permissions may be set incorrectly.
OpenGL Renderer: GeForce Go 7300/PCI/SSE2
It does the render, but on the machine_A graphic card.
Then, I don't understand how to render without any user connected to
machine_B.
Thanks for you help guys.
