yesterday,this problem occur,and i try to restart my PC so many time but problem still there. today,when i use the ubuntu(10.04) ,the "Update Manager" pop a window to tell us to update,i do so. then i try to run rviz again,awesome it works!!

ok,i still don't how the problem is solved,but it works anyway.

When I run the command

$ rosrun rviz rviz

It fails with:

The program 'rviz' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadLength (poly request too large or internal Xlib length erro'.
(Details: serial 17 error_code 16 request_code 153 minor_code 17)
(Note to programmers: normally, X errors are reported asynchronously;
that is, you will receive the error a while after causing it.
To debug your program, run it with the --sync command line
option to change this behavior. You can then get a meaningful
backtrace from your debugger if you break on the gdk_x_error() function.)

It seemed to happen out of nowhere. It was working before.

hi all, how to use door_handle_detector (http://www.ros.org/wiki/door_handle_detector) to detect a door or a handle?

i plugin kinect in the PC,and try this command in terminal:

roslaunch door_handle_detector door_closed_40.launch

(there are lots of *.lauch ,

bag_detector.launch
door_closed_39.launch
door_closed_40.launch
door_closed_alex.launch
……

i don't konw which one to use ,so i random select one to see what result will be)

BUT,i get ERROR as follows:

FATAL] [1318863811.703771799]: Failed to open file: /opt/ros/diamondback/stacks/pr2_doors/door_handle_detector/test/door_closed_40.bag (Error opening file: /opt/ros/diamondback/stacks/pr2_doors/door_handle_detector/test/door_closed_40.bag) [rosplay-6] process has died [pid 21335, exit code 1]. log files: /home/mochen/.ros/log/2d2db2aa-f8d1-11e0-8185-00218545f6b8/rosplay-6*.log

-------------------------ths to David , added ------------------------------ (just use an kinect to detect door or handle,without other camera sensor or laser)

roslaunch door_handle_detector door_handle_detector_vision.xml

get an error:

core service [/rosout] found
ERROR: cannot launch node of type [stereo_image_proc/stereoproc]:
Cannot locate node of type     [stereoproc] in package [stereo_image_proc]

the program doesn't crash down,it still running,some info in terminal as follows: **process[handle_detector_vision-2]: started with pid [2447] (0): /opt/ros/diamondback/stacks/pr2_doors/door_handle_detector/bin/handle_detector_vision (1): stereo:=narrow_stereo (2): __name:=handle_detector_vision (3): __log:=/home/myname/.ros/log/ebf7adc4-f923-11e0-8cd6-00218545f6b8/handle_detector_vision-2.log but wait for a long long time,it is still loading the /opt/ros/diamondback/stacks/pr2_doors/door_handle_detector/data/handles_data.xml .

so waht is the problem now,how to solve it?ths!

use Kinect,ubuntu 11.04 ,ROS version is diamondback,PCL1.2.

[rospack] couldn't find dependency [mapping_msgs] of [skeletal_tracker] THE problem is it lacks mapping_msgs package !!

solution :

1.just download mapping_msgs(http://www.ros.org/wiki/mapping_msgs),via :

svn co https://code.ros.org/svn/wg-ros-pkg/stacks/motion_planning_common/trunk/mapping_msgs

,and then :

rosmake mapping_msgs

2. when building mapping_msgs ,it throw problem that it lacks : [rospack] couldn't find dependency [geometric_shapes_msgs] of [mapping_msg

download geometric_shapes_msgs,and then rosmake it.all will be ok !!

enjoy it !!

my system is ubuntu10.04 (32bit) ,installed with ROS( diamondback) and openni_kinect.

i want to use the mit kinect demo,then i fellow the guide from http://www.ros.org/wiki/mit-ros-pkg/KinectDemos/dback

1. BUT in step 6 ,i get a WARNING as follows:

 WARNING: Skipped command line arguments: ['ni'] because they could not be resolved to a stack name or a package name.

2. again i get a ERROR in step 7,
