So it is not just me then..
It seems like they are on the bug report, i guess i should have posted one myself when i encountered the problem
Lets hope someone finds a solution, I will probably spend some time on it, not sure when though...

There seems to be some issues with using SDL2/PySDL2 on Linux, but Windows and Mac OSX seems unaffected. There's a few issues that we have seen, but we missed the "Config device mapping" bug
I've added an issue for it
here and I've just pushed a workaround fix for it.
The others we found are:
- Opening OS dialogs crashes the application, there's a workaround for opening the Browse dialog for the bootloader
- Crashing when closing the application (issue)
All of these happen during calls to libraries, so the best we have been able to do right now is working around the issues. When we have more time we will investigate it more.

Fatal Python error: (pygame parachute) Segmentation Fault
Abort trap: 6
This happen if I have the crazyradio 2 connected or disconnected. Any thoughts?
It seems that this is an old client since the pygame exception parachute is catching the exception. Could you update to the latest one? To get a better error message try bootloading the Crazyflie (menu
Crazyflie->Bootloader and
Initiate cold boot). The error is probably caused by permission issues when opening the Crazyradio USB device. For fixing this have a look at adding the UDEV rules we use in the Bitcraze VM (info
here).

Yes it was an old client
I had first cloned the repo from bitbucket, then realized it had moved over to github. Should of known something was up since the last commit in the bitbucket repo was from 2013

The latest version in the repository on master should fix this error (among others). SDL2 is not used on Linux anymore, the devices are accessed directly by /dev/input/js*. If you feel up for it then pull the latest version and try it out, if you find any issues let me know.

Happened to me too when installing via setup.py. I think there's a package definition missing in there, as it works when starting locally from source.

There are some
new commit to the client now that hopefully fixes the linux problems.

Shouldn't `cfclient.utils.joystick` be added to the setup.py `packages` argument to fix the error reported above?
