How to reset settings without launching the game? (Linux)

[workforce]

I'm running the game on an asus eee pc laptop with linux mint 14 installed. I foolishly changed the game to use one of the openGL renderers and now the game runs  painfully slow. It takes somewhere between one and two minutes to draw a single frame! Is there a way to reset the game to default settings? I have tried uninstalling (complete uninstall) and re-installing but it didn't work.

You should find your settings in one of these folders, just delete the options.cfg and it'll be reset to default.

options.cfg was located in ~/.config/openxcom.

deleting i worked perfectly. Thanks for the help!
