After further reading, I understand that 'nvidia-xconfig' can be used to
configure a "headless" configuration. I did NOT do this because I was not
aware of it. However, I am not sure that would help me resolve the
original issue with XINERAMA extension.
To generate my xorg.conf I did two things.
1. Run "nvidia-xconfig" without any parameters
2. Modify xorg.conf manually add 4 "device" stanzas with BusID for each
device. Xorg would fail to start with "unknown device" error before that.
Now Xorg starts great.
In case its helpful, here is my complete xorg.conf
# cat /etc/X11/xorg.conf
# nvidia-xconfig: X configuration file generated by nvidia-xconfig
# nvidia-xconfig: version 340.32

Subject: [VirtualGL-Users] Xinerama inside TurboVNC
Hi All,
I have following setup:
1 x GPU server (remote) w/ two NVIDIA Tesla cards running CentOS 6.6
NVIDIA 240.30 drivers installed
VGL 2.3.3 installed
TurboVNC 1.2.2 installed
My thin client is Windows 7 with TurboVNC client running.
I have tested that VGL runs Ok by running glxspheres64 and Google Earth.
The application I'm having problem running is Unigine Heaven benchmark.
I launch the application like this:
# vglrun ./heaven
The error I get is following:
Xlib: extension "XINERAMA" missing on display ":1.0".
X Error of failed request: BadRequest (invalid request code or no such
operation)
Major opcode of failed request: 138 (RANDR)
Minor opcode of failed request: 8 (RRGetScreenResources)
Serial number of failed request: 10
Current serial number in output stream: 10
AL lib: ALc.c:1879: exit(): closing 1 Device
AL lib: ALc.c:1808: alcCloseDevice(): destroying 1 Context(s)
Display 1:0 is my TurboVNC session. It seems XINERAMA extension is missing
inside my VNC X11 display. I don't know how to enable it.
I have tried to enable XINERAMA inside of my system X11 display ":0" by
adding following to xorg.conf
option "xinerama" "on"
This works fine. I can see in Xorg.0.log file that Xinerama is enabled.
But, even after restarting TurboVNC session, the Xinerama extension is
still missing inside VNC. There does not seem to be any obvious way to
include the xinerama extension with "vncserver" command when creating the
VNC X11 display.
I'd appreciate any help/suggestions to help me resolve this issue.
Thanks in advance,
Ben
