rviz error. segmentation fault (core dumped)
trying to run step 5 in introduction to tf tutorial http://wiki.ros.org/tf/Tutorials/Introduction%20to%20tf rviz doesn't open and i get the following error
IBUS-WARNING **: Unable to connect to ibus: could not connect: connection refused. Segmentation fault (core dumped)
what isn't working?
UPDATE I deleted the ibus folder from .config/ and now i don't get an ibus warning BUT rviz still doesn't open

Found Solution: https://github.com/ros-visualization/rviz/issues/975
the solution was update the graphics library: http://ubuntuhandbook.org/index.php/2018/01/how-to-install-mesa-17-3-3-in-ubuntu-16-04-17-10/
Now my rviz program runs.

I'm not having a problem with the ibus warning anymore but now I just get a warning about accessibility bus. what is that?

RViz issues are typically caused by missing GPU drivers, faulty GPU drivers, or running in a virtual machine (or under WSL on Windows 10).
What sort of hardware do you have?

I'm using Xubuntu 16.04. I have a laptop that i dual booted with Windows and Xubuntu. Running Rviz through Xubuntu of course. Anyway to update the GPU? It has worked previously with my laptop but haven't gotten it to work this time around.
