Today I upgraded to Gazebo-1.8 and DRCSim-2.6 and now I encounter a problem after running "roslaunch atlas_utils atlas.launch". Gazebo fails to start properly and freezes in a gray screen then dies. This the message I get:

  [ WARN] [1369173843.179656077]: The input topic '/multisense_sl/camera/left/image_raw' is not yet advertised
  [ WARN] [1369173843.179814558]: The input topic '/multisense_sl/camera/left/camera_info' is not yet advertised

  [ WARN] [1369173843.179875473]: The input topic '/multisense_sl/camera/right/camera_info' is not yet advertised
  [gazebo-1] process has finished cleanly

Thanks for any help,

My first guess is that you're using a non-NVIDIA GPU. There are reports that the change in drcsim 2.6 to using the GPU for laser scan generation causes gazebo to crash immediately on Intel GPUs.

There's a proposed patch that adds launch files to let you bring up simulation using the CPU-based laser. You might try that.

I have two laptops with Intel GPUs and they both show same issue with launching atlas. I will try to use that patch. Thanks. By the way, how can downgrade to DRCSim-2.5?

All previous releases are [archived](http://gazebosim.org/assets/distributions/). You can download the `.deb` files for specific versions and install them manually with `dpkg`, instead of `apt-get`. If you go back to drcsim 2.5.x, also go back to gazebo 1.7.x and sandia-hand 5.1.13.

I had this problem with the latest (stable) version of gazebo (1.8.0) and drcsim (2.6.1). I also had an error about the connection manager - possibly also related to this question [link].

The solution for me: My laptop has two graphics cards - Intel and NVidia, and it uses optimius to power save. In Ubuntu, only the Intel video card could be used. I installed the nvidia-current driver and then disabled optimus in BIOS, and everything works perfectly.

Agree with both comments above. Additional solution, if the machine has both Intel and NVIDIA GPUs, is to run drcsim through bumblebee:

optirun roslaunch atlas_utils atlas.launch
