Hi, I bought turtlebot full kit and am trying to move it.
However, I got some errors in this tutorial(Looking at Camera Data : http://www.ros.org/wiki/turtlebot/Tutorials/Looking%20at%20Camera%20Data).
I couldn't launch rviz with Asus EeePC. How do I solve it ?

I'm using Asus EeePC 1215B(This is a default PC for turtlebot).
It has Ubuntu 10.04 and ros electric.
I've already confirmed that turtlebot can be moved by teleoperation(turtlebot_teleop), so I think RobotSetup is correctly done.

I found one of the solution here(http://answers.ros.org/question/2109/rviz-in-ros-electric?answer=3627#3627), but I couldn't understand how to solve it in my case because of different configuration.

Here, I show the log data including four results.
1. terminal error1 : rosrun rviz rviz (on turtlebot laptop)
2. Ogre.log : got by the command "rosrun rviz rviz -l" (on turtlebot laptop)
3. terminal error2 : rosrun rviz rviz (on workstation)
4. troubleshooting : the result I got when I followed this page(http://answers.ros.org/question/2109/rviz-in-ros-electric?answer=3627#3627)

Thanks in advance.

Could you please reformat your posting? For terminal output please prefix all lines with ' ' (four spaces) to preserve its formatting. A blockquote (prefix lines with a '>') is also acceptable. See markdown/syntax for more information.

Thank you for your advice, ipso. I made it and added some info.If it doesn't look good, please say it.

rviz needs a working OpenGL setup, which means you need a proper installation of the drivers of your graphics card. The Radeon of the EeePC 1215B should be capable of running rviz, but it most likely needs the proprietary AMD drivers for it (the open-source drivers don't provide sufficient 3D acceleration as of this time AFAIK).

~~The output of glxinfo you posted indicates that you're currently making use of the default Mesa drivers, which is insufficient for rviz / OpenGL.~~

EDIT3: all wrong, OpenGL was working, OGRE needed OGRE_RTT_MODE=Copy again. See @weiin's answer (and the comments).

EDIT:

//terminal result (on workstation)
turtlebot@turtlebot-laptop:~$ rosrun rviz rviz Error: Unable to initialize 
gtk, is DISPLAY set properly?

Is this in a SSH session from your workstation to the EeePC? If so, this error is 'normal': your SSH session has no access to any running X instances.

EDIT2: Perhaps you should provide some more info on your setup. Which drivers have you installed, and which versions are they? What OS are you running? etc

I don't think the default Mesa drivers are insufficient. My glxinfo output is the same (OpenGL version string: 2.1 Mesa 7.7.1) and I run rviz quite fine. Running 'glxgears' should show whether OpenGL can work on the current drivers

weiin ( 2012-07-08 22:12:02 -0500 )edit

Ok, that's why I added that my comment was 'as far as I know'. Perhaps you could post some more information on your setup (if it is relevant)?

Thank you for your comments, ipso and weiin.

>Is this in a SSH session ... ? Yes, exactly. Thank you, I got it.

>Which drivers ... ? I added some infor the bottom of the above sentences.

I ran 'glxgears' and it worked well.

Based on a google search of your OGRE_EXCEPTION, you will find my previous question having the same exception here. Your glxinfo shows the same as mine when I had the problem (the "shading version" is missing).

When you ssh into turtlebot laptop from your workstation, you will not be able to run rviz (or any other X terminal for that matter) as ipso pointed out. If you insist on having rviz through ssh, you can use ssh -X turtlebot@turtlebotsIP, but note that the update will be slow(er).

Thank you, weiin. I tried followings. (1). "glxinfo | grep direct" and saw LIBGL_ALWAYS_INDIRECT is NO(echo $LIBGL_ALWAYS_INDIRECT result in 1) (2). export the variable = 0 and echo again, however saw it was 1.

moyashi ( 2012-07-09 18:54:26 -0500 )edit

(3)Alt + F2 -> gnome-terminal and did (1), (2). But I got the same results. (4)Alt + F2 -> xterm and did (1), then I saw LIBGL_ALWAYS_INDIRECT is YES. (5)"rosrun rviz rviz" in xterm then I got the error "Texture for pass 0: creating with size 1x1 segmentation fault". Should I update all packages?

moyashi ( 2012-07-09 19:02:37 -0500 )edit

I found the temporary solution here. (http://answers.ros.org/question/12140/how-to-run-rviz-with-ogre_rtt_mode-set-to-copy-or/) "(1)export OGRE_RTT_MODE=Copy, (2)rosrun rviz rviz", then it works well. But I can't understand the meaning. Is it good to avoid the errors?

moyashi ( 2012-07-09 19:31:20 -0500 )edit

I think this http://unix.stackexchange.com/questions/1437/what-does-libgl-always-indirect-1-actually-do explains the direct rendering part quite well. Seems like RViz can only work with direct rendering. Segfault problems/solutions can be found here: http://ros.org/wiki/rviz/Troubleshooting
