Hello, all

I am new in ROS system.
I started to subscribe this mailing list this month,
so my problem might be solved already.
The problem is quite common, and I think it's better ask it to professionals.

The problem I have is already mentioned in "No OpenGL Support" in following URL.

http://www.ros.org/wiki/rviz/Troubleshooting

I installed ROS system on a Vmware virtual machine with Ubuntu 9.04 distribution.
The virtual machine is on Windows XP Professional SP3.
My laptop is lenovo X61, which has Mobile Intel(R) 965 Express Chipset Family as a video card.

The version of the virtual machine is...

# uname -a
Linux ubuntu 2.6.28-18-generic #60-Ubuntu SMP Fri Mar 12 04:40:52 UTC 2010 i686 GNU/Linux

And when I execute "rviz", I got an error.

# roscore
# rosrun rviz rviz
rviz: OgreGLSupport.cpp:57: virtual void Ogre::GLSupport::initialiseExtensions(): Assertion `pcVer && "Problems getting GL version string using glGetString"' failed.
/opt/ros/boxturtle/ros/bin/rosrun: line 35:  7245 Aborted                 $exepath "$@"

As the web page suggests, I turned on "3D graphics acceleration" in the virtual machine setting,
(there is a setting for the acceleration in VMware workstation)
and I checked whether 3D acceleration is working.
and I got

# glxinfo | grep render
direct rendering: Yes

in the virtual machine. It seems to be OK, but the rviz still give the same error.
I tried to fing a driver of the video card. (Mobile Intel(R) 965)
However, I couldn't find it for Ubuntu.
Do you know any suggestions? or is there actually a driver for that?

In the virtual machine, the video card is still recognized as following.

# lspci | grep VGA
00:0f.0 VGA compatible controller: VMware Inc Abstract SVGA II Adapter

Is this a problem?
I am also quite wondering if my xorg.conf is OK.

# less /etc/X11/xorg.conf

...(some comments)...

Section "Device"
    Identifier    "Configured Video Device"
EndSection

Section "Monitor"
    Identifier    "Configured Monitor"
EndSection

Section "Screen"
    Identifier    "Default Screen"
    Monitor        "Configured Monitor"
    Device        "Configured Video Device"
EndSection

(END)

I don't know if this is enough information to solve this problem.
Any advices are welcome, solution for any other video cards is also welcome.

Thanks in advance.
