Hi,
I installed VirtualGL 2.3.3 on Centos 6.5 64bit
$ yum list installed | grep Virtual
VirtualGL.i386 2.3.3-20131014
installed
VirtualGL.x86_64 2.3.3-20131014
installed
and I have 2 GPU card installed
$ lspci | grep VGA
03:00.0 VGA compatible controller: NVIDIA Corporation GK104 [GeForce GTX
670] (rev a1)
84:00.0 VGA compatible controller: NVIDIA Corporation GK104 [GeForce GTX
670] (rev a1)
In the xorg.conf I have 2 ServerLayout, which connect
"screen 0" to bus 03:00.0 and "screen 1" to bus 84:00.0
Section "ServerLayout"
Identifier "Layout0"
Screen 0 "Screen0" 0 0
InputDevice "Keyboard0" "CoreKeyboard"
InputDevice "Mouse0" "CorePointer"
EndSection
Section "ServerLayout"
Identifier "Layout1"
Screen 0 "Screen1" 0 0
InputDevice "Keyboard0" "CoreKeyboard"
InputDevice "Mouse0" "CorePointer"
EndSection
Then I started two 2D real X server which attached to Screen 0 and Screen 1
respectively.
$ X :0 -layout Layout0 &
$ X :1 -layout Layout1 &
And start a xvfb server as dummy x server
$ Xvfb :2 -screen 0 1024x768x24 &
When run glxspheres using gpu 0
$ DISPLAY=:2 vglrun -d :0 +v +tr /opt/VirtualGL/bin/glxspheres
This one runs well
But when run glxspheres using gpu 1
$ DISPLAY=:2 vglrun -d :1 +v +tr /opt/VirtualGL/bin/glxspheres
This time is very weird, the fps ~= 1
the log shows glXSwapBuffers cost almost 1ms

But when running glxspheres64, both gpu 0 and gpu 1 work well.
What should I do to let 32bit on 2nd GPU works?
Thanks.
