Dex won't boot on Ubuntu 15.10. It dies with the following message:

I know the game only has a 32 bit version, and I have installed all the appropriate drivers, and have up-to-date graphics drivers for my Nvidia 770GTX.

I have tried just booting the game directly with and without the -force-open-gl flag. It dies with the highly similar message:

Trying to start GamepadConfigTool.x86 and GamepadConfigTool.x86_64 yields the same error, as does launching the game directly with the -t flag.

Can anyone offer any suggestions?
