[ros-users] [Discourse.ros.org] [Next Generation ROS] Rviz2 - Qt - problem creating accessible interface

[Arunava Nag]

I have been exploring AA (Ardent apalone) release. 
**Rviz2 is not showing any interface.**

when i launch **rviz2** in the terminal:

    [INFO] [rviz2]: Using FSAA from GL_ARB_multisample extension.
    [INFO] [rviz2]: Texture: Warning: Loading 1 faces(PF_R5G6B5,8x8x1) with 3 hardware generated mipmaps from Image. Internal format is PF_R5G6B5,8x8x1.
    Problem creating accessible interface for:  rviz_rendering::RenderWindow(0x2463020) 
    Make sure to deploy Qt with accessibility plugins.

Thats the error I am getting. My rviz2 interface looks like this:

**RVIZ2**

_I tried troubleshooting  re-installing the qt libraries , qt creator._ 

Also, I was trying out the [dummy_robot](https://github.com/ros2/ros2/wiki/dummy-robot-demo) demo and I have to do:

`ros2 run ros1_bridge dynamic_bridge --bridge-all-2to1-topics` 

for terminal 2 section in wiki. 
It will not work for me as shown in the wiki: 

`dynamic_bridge --bridge-all-2to1-topics`. 

[_I tried building ros_bridge1 separately using ament build and checked the CmakeLists as well the custom_executable section._ ] 
Additionally in Rviz (ROS1) it throws error with the RobotModel visualizatin .

**Error In Rviz1**:

    [ WARN] [1513236342.717209109]: OGRE EXCEPTION(6:FileNotFoundException): Cannot locate resource package://rrbot_description/model/meshes/hokuyo.dae in resource group Autodetect or any other group. in ResourceGroupManager::openResource at /build/ogre-1.9-mqY1wq/ogre-1.9-1.9.0+dfsg1/OgreMain/src/OgreResourceGroupManager.cpp (line 756)

**RVIZ1**

Any hints or solution would be appreciated.
